AL-3 Monitor Optimises Analogue Signalling Devices

IFM Electronic has introduced the AL-3 monitor, which complements analogue signalling devices by allowing the user to set switchpoints and compare or combine values and scaling ranges. The AL-3 monitor is a programmable, two-channel analogue threshold relay with two inputs for analogue standard signals (0/4...20 mA). It picks up the current signals on separate inputs, compares them with the set limit values and switches the outputs according to the set switching functions. The input signals can be scaled to the measuring range of the sensor or transmitter so the measured values are indicated on the front display corresponding to their physical unit. The AL-3 features an output relay with changeover contact and a transistor output for each channel. The user can monitor values that exceed or fall below the limit values and window function. In the comparator operating mode, a differential pressure can, for example, be determined from the two input signals, monitored and provided as an an

Schunk Intec Designs Three-Finger Centric Grippers

Schunk Intec has created the PZB-plus series of three-finger centric grippers with a central bore designed as a fitting. The central-bore feature is equipped with female threads for customer-specific add-ons and can be used as an ejector or to supply material. The PZB-plus can also be used to monitor the handling or assembly process with a camera system or to pick up workpieces and centre them using the fitting during the gripping process. There are also threads integrated on the upper face of the gripper and on the cover plate to facilitate mounting customer-specific add-ons. The PZB-plus is available in two different stroke-length versions; the smaller stroke results in approximately double the gripping force. The six sizes, ranging from 64mm to 200mm, are fitted with multi-tooth guides, as is the case in the PGN-plus and PZN-plus ranges. Compared with the PZB series, the PZB-plus can pick up 100 per cent-higher torques in directions at right angles to the gripping motion. This make

Aalborg Releases Direct-Reading Flowmeters

Aalborg Instruments has introduced direct-reading scales for Models P, S and T flowmeters. Direct-reading flow-tube scales are designed for a specific gas or liquid at a given temperature and pressure, valid only for the associated units of flow. Flow rates for a specified set of parameters are clearly indicated in specific engineering units, such as ml/min or scfh. Using correlating tables and graphs to determine flow rates is no longer necessary. NIST-traceably calibrated for specific liquids and gases, these units are ideal for OEM applications and processing industries. Direct-reading scales are available for argon, carbon dioxide, helium, hydrogen, hydrogen chloride, methane, nitrous oxide, oxygen and propane.

The Freja 306 features extended Hi-Current outputs, rugged construction and a wide operating temperature range, making it ideal for field use. It is suitable for use as a stand-alone device, or in conjunction with a PC running the Freja WIN software package. In either case, the operation of the instrument is straightforward and intuitive, with Freja WIN adding the benefits of a highly intuitive graphical user interface, as well as enhanced options for automated testing. The outputs of the Freja 306 can be configured as 3 x 15A plus 3 x 35A, or as 1 x 100A. The outputs with a 35A rating are particularly useful when testing 5A relays, while the capability of these outputs of generating up to 50V eases the testing of many types of electromechanical relay. The Freja 306 also provid

Windcon 3.0 Features CAN-Bus Interconnectivity

SKF has launched Windcon 3.0, the third-generation version of its wind turbine condition monitoring system. SKF Windcon 3.0 is designed to enable wind farms to extend turbine maintenance intervals, manage resources more effectively, and avoid downtime. The new Windcon system features CAN-bus interconnectivity to a number of systems typically found in modern wind turbines, such as centralised lubrication, blade monitoring, and gearbox oil condition systems. These elements can be remotely monitored at any maintenance centre with internet access, using SKF Webcon software. Using vibration sensors mounted on a turbine's main shaft bearings, drive train gearbox, and generator, SKF Windcon 3.0 collects, analyses, and compiles a range of operating data that can be configured to suit a wind farm's specific requirements. The collected data enables root cause failure analysis to eliminate recurring failures and keep costs down. A brochure is available to accompany the solution, which ex

PDU2M Added To Belt-Driven Linear Motion System

Hepcomotion has introduced the PDU2M to its Profile Driven Unit (PDU2) belt-driven linear motion system. The company said the PDU2M delivers a 200 per cent increase in moment load capacity and 1000 per cent uplift in moment load stiffness compared to a standard PDU2. Direct load capacity is also 50 per cent greater. In practice this means, for example, that designers can use a single PDU2M unit as a horizontal axis in an X-Z system, where previously two PDU2 units working in parallel would have been required to provide the necessary rigidity and strength. Key to this capability is the high-performance Hepcomotion Herculane wheels that are mounted on adjustable eccentric studs. These wheels run virtually friction-free on the inside of the profile, providing stable support for the carriage plate. Felt wipers sweep debris from their path. The unit is available with a number of carriage designs to allow the quick and easy construction of multi-axis systems with a minimal requirement for b

Segway Transporter Uses Novotechnik Sensor

The steering system of the two-wheeled Segway Personal Transporter (PT) utilises an angular position sensor from Novotechnik to aid balance and acceleration of the vehicle. The second-generation PT is a self-balancing transportation device with sophisticated motion and stabilisation technology that uses the rider's natural body movements to propel and steer the vehicle. The vehicle can hit 12.5mph and covers a range of 24 miles. The Segway PT uses its Leansteer steering system to allow the riders body movement to guide the vehicle, while the Segway Smart Motion (SSM) controller uses the same information to maintain motion and direction with complete dynamic stability through its balance sensor assembly (BSA), which has integral solid-state rate gyro and tilt sensors. In operation, the rider simply moves forwards, backwards and to each side to propel and steer the PT in the corresponding direction while the control system ensures that bumps, camber or uneven slopes, which may affec

Ansys Application Enables 3D Structural Analyses

SMC has appointed Idac to develop a macro that will allow SMC engineers to predict the deflections and stresses seen by the telescopic communication masts the company manufactures. SMC is regularly required to design and manufacture telescopic communication masts, which are customised to handle customer-specified load configurations. The deflections of the mast must be kept within a very tight tolerance for proper operation. Stresses also need to be kept within specified limits. SMC required an automated procedure to analyse different design configurations based on a number of predefined design variables under a given set of loads. This would require a set of input design variables to be supplied by a 'user' to the Ansys software, which would then create the Finite Element (FE) Model to be analysed, solve the FE Model and post-process the results into a set of text files and graphical plots for final assessment by SMC. Idac was required to develop a macro that would allow SMC

Balluff Reveals Flush-Mountable C-Slot Sensor

Balluff has expanded its range of miniature BMF magnetic field sensors with the BMF 204K, a flush- mountable C-slot sensor with integrated holding. With a length of just 20mm, it disappears in the C-slot without protruding. This makes it ideal for use in short-stroke cylinders, mini-grippers and other space-critical applications. Installation of the BMF 204K is easy: the integrated holding element allows you to slide the sensor into the slot, position it and turn a screw to tighten. It features high accuracy, short over-travel distances and low hysteresis. The sensor is optimised mechanically for the Festo C-slot, but also fits other slot styles such as SMC. It is available in a cable version with IP67 plastic housing and PNP normally-open output, and pigtail versions with M8 connector and cable lengths of 0.3 and 0.5m. BMF sensors detect individual positions, such as end of travel on pneumatic cylinders, wear-free and precisely and can 'see' the permanent magnets installed on

SMAC Creates Tapping Process For Watch Maker

SMAC has developed a linear/rotary actuator, the LAR35 series, as a tapping process for a watch manufacturer in Switzerland. The tap diameter is 0.38mm; the part has a diameter of 3mm and is 0.25mm thick. The LAR35 series has a 50mm stroke and is mounted vertically with the shaft looking down. The custom tip is attached to the shaft end of the actuator to hold the tap.The shape of the parts can be varied so that the customer can hold the part to tap manually, while the fixture is being developed. SMAC's patented soft-land capability allows the tool to land on the part gently, move back 0.1mm, start the rotation, press the linear axis with a small force, check any variation on torque on the rotary motor to avoid failure and check the linear position when the tap reaches the required position. The same procedure takes place in reverse. For the SMAC LAR series, linear and rotary are combined in one unit. With all SMAC actuators, force, speed and position are fully programmable.

Precision Micro Develops Etching Process

A team at Precision Micro has developed a process to make Elgiloy, an austenitic super alloy, 'etchable'. Elgiloy is based on cobalt and is an erosion and corrosion-resistant stainless steel. Photo etching is a manufacturing technology that produces intricate, burr free, stress free, high-precision profiles by a process of controlled erosion. On the face of it, Elgiloy and photo etching should be incompatible. This was the case until the process development team at Birmingham-based Precision Micro came up with a process route that the company claims has solved the problem. 'The solution does not just involve a combination of etchant chemicals,' said Bob Crutchley, director. 'A methodology has been developed, whereby a treatment is applied prior to etching and a catalyst is introduced during the etching process itself,' he added. The process utilises standard photo resist materials and chemicals that have no exceptional hazard risk. It is designed to enable engi

Noax Unveils Electrically Isolated Plug-In Module

Noax Technologies has added an electrically isolated RS 232 plug-in module to its range of industrial PCs. With the module, port data is transferred using a powerful data coupler instead of a direct electrical connection. The electrical connections between the Noax industrial PC and the peripheral devices that are connected to the port are isolated in order to ensure that all components are effectively protected from interference voltages. With this development, the IPC specialists from Germany are targeting industrial machine control applications. Under certain adverse conditions (for example, with poor power supply systems, neutral reference levels or high differences in potential), the RS 232 connection may transfer unwanted currents between the machine and the industrial computer. The damage caused may range from disruption of the data transfer to hardware failure. Noax said that this electrically isolated port module guarantees a high level of reliability for data transfer as wel

The range also includes 5, 12, 15 and 48V models.

Ultrasonic Inspection Detects Pipeline Defect

Ultrasonic inspection involves transmitting sound waves of short wavelength at high frequencies to identify flaws, measure the thickness of materials or detect corrosion. Conventional ultrasonic testing equipment sends a pulsed beam of high-ultrasound from a handheld transducer, which is placed upon the surface of the object being tested. This wave is disturbed and then partially returned from spots with internal imperfections or from the back of the material wall. Capturing and analysing the return sound can show the amplitude of the pulse and the duration taken for return to the transducer. By measuring this sound, a skilled operator can identify the location and orientation of imperfections and the wall thickness. Acceptance criteria define whether or not the indication is a defect. Ultrasonic testing is now being used more often for inspection than the traditional balance between radiographic testing and ultrasonic testing - especially for pipelines. SGS has good experience of fai

High Z vs Low Z - Optimized Drive Reactors

Line Reactors enhance the performance and protect variable frequency drives by providing impedance. Impedance, or Z, in an electrical circuit is a measure of the total opposition to current flow. “Low Z” line reactors provide a lower amount of impedance, while “High Z” line reactors provide a higher amount of impedance. This article addresses the use of line reactors on the line side of variable frequency motor drives, not the output side of drives. When to use “Low Z” Line Reactors? Variable frequency drive applications where a reactor is desired to prevent the possibility of drive problems associated with minor line voltage surges. Drive damage or fault conditions are not expected but could result. In virtually all applications, an inductor in front of the drive can be a measure of protection to extend the service life of the drive. Many low horsepower “micro” drives are proved as a low cost option for motor speed control or perhaps phase conversion. These are cost effective entry-l

Smith & Wesson Uses Enovia PLM

Smith And Wesson , manufacturer of firearms and safety/security products, has chosen Enovia PLM to improve the efficiency of its product design and development process. This will enable employees across the globe to collaborate on designs and share up-to-date product information. Smith and Wesson will use Enovia to create a centralised database allowing common parts identification and more efficient capture and reuse of its institutional knowledge. Initially started as a process to replace the company's paper-based systems, Smith and Wesson opted to go forward with Enovia Engineering Central to manage all of its engineering change requests and orders (ECR/ECO), automate business processes and create a centralised database. Since then, the company's phased adoption of PLM has evolved to where each additional process enhances the ability of virtually any user to more efficiently accomplish tasks such as engineering changes and frame marking identification. Its implementation has

Bentley Uses Aesthetica Simulation Software

Bentley Motors has implemented Icona's perceived quality simulation software, Aesthetica, at its design and manufacturing plant in Crewe, England. It is being used to streamline and improve the process of achieving consistently high perceived quality in the company's vehicles without negatively impacting development timescales and manufacturing costs. The software has been introduced to help overcome the difficulties of getting all stake-holders in the vehicle design and development process - styling, engineering, quality and manufacturing personnel - to agree at the most appropriate stage in the development process on the assembled conditions to which the Class A surfaces should adhere. Jim Shaw, manager of concept engineering at Bentley, said: 'The practicalities of getting everyone involved to agree the gap and flush conditions ahead of the Class A surfacing process meant there was a reluctance to commit to them early enough in the design process. 'This was resultin

SGS Completes LNG Design Verification

In just four months, SGS Industrial Services has completed the design verification of three cryogenic liquefied natural gas (LNG) tanks in accordance with Canadian code CSA Z276-01. Canaport LNG in Saint John, is a consortium between Irwing Oil, New Brunswick and Repsol, Spain, constructing the first LNG receiving and regasification terminal in Canada. After four years under construction, the Canaport LNG terminal should begin operations in the second quarter of 2009 and supply natural gas to the Canadian and American markets. With its three large LNG cryogenic tanks, the first Canadian LNG terminal has a capacity of one billion cubic feet or 28 million cubic meters of natural gas per day and represents a capital investment of CAD750m (GBP413m). A project of this magnitude requires a strong international team in order for it to be completed in such a tight timescale. SGS Canada contributed to this success with its experienced team of engineers and professionals. In four months, SGS su

Hi-Line Unveils Compressed Air Filter Units

A range of compressed air filter units from Hi-line has been designed for the removal of oil, water, particulates and gaseous aerosols from compressed air systems. The die-cast filter housings are produced from high-grade aluminium with external and internal surfaces being alu-chrome treated. They are also subject to a tough epoxy baked-on paint finish in 'compressed air blue' - RAL 5015. These treatments are designed to provide long-term protection, even when subject to the harshest operation conditions, ensuring a long service lifetime. Optional electronic or pneumatic differential pressure gauges can be fitted as required. The oil/water condensate is removed via a highly efficient robust brass drain assembly with the built-in capability to attach a 6mm dia nylon condensate discharge line. The filtration elements use pleated filter media that combines maximum efficiency with very low differential pressure drop. They are available in several grades to accommodate particle rem

Hytrol Uses Tolomatic Rodless-Style Actuators

Tolomatic is supplying rodless-style actuators to Hytrol Conveyor Company, a producer of conveyor systems, as a space-saving solution. Engineers at Hytrol needed a space-saving solution for designing a diverter for an overhead pull-off system that would divert 150lb boxes to a different conveyor line. Manufacturing and packaging facilities may move and sort tons of bulk on conveyors, but the sorters, diverters and pull-offs that route products to their next destination must be as trim as possible to make the most of valuable floor space. Jackie Smith, application engineer at Hytrol, said: 'Our conveyors are used to move products down the line, divert them to the next station in the manufacturing process or, if a product is defective, divert them to a reject line. 'When we needed to design a diverter that was more compact and could be simply integrated into our systems, we decided that we needed to employ a different type of actuator.'.
