Fluke Defines Terms Associated With Vibration

Fluke provides a basic glossary of vibration terms for those involved in equipment maintenance and vibration diagnosis. Vibration is said to be one of the earliest indicators of a machine's health. Understanding why vibration occurs and how it manifests itself is a key first step towards preventing vibration from causing trouble in the production environment, according to the company. Acceleration is the rate of change of velocity often depicted as 'g' or in 'mm/s2' in the metric system and 'in/sec2' in the English system. Acceleration is not constant but will vary through the vibration cycle, reaching maximum levels as velocity reaches its minimum. This is typically when a particular mass has decelerated to a stop and is about to begin accelerating again. Next, an accelerometer is described as a transducer whose electrical output responds directly to acceleration. Accelerometers typically cover a much wider frequency range, along them to pick up signals n

The duplex filter system, which utilises a combination of stainless steel wedge-wire and mesh filter screens, is designed to offer high product security as well as a consistently filtered product. Axium's range of 316L stainless steel Pure-Screen wedge-wire filters is being used throughout the confectionery, food, beverage, cosmetics, and pharmaceutical industries. It is ideally suited for liquid viscous products such as chocolate, yoghurt, butter, soft cheese, creams and sauces as the wedge-wire filter elements remove unwanted particles and blend and mix any non-dissolved materials in suspension, resulting in a consistently smooth product throughout

Solidworks Aids HTO Axial Diesel-Engine Design

Shepherd's High Torque Output (HTO) axial diesel engine, designed using Solidworks 3D CAD/CAM software, quadruples the torque of a traditional crankshaft engine while consuming half the fuel. Said to be more powerful and environmentally friendly, as well as cheaper to build and run, it has fewer parts than a traditional diesel engine, no intricate castings or complicated machining and can be assembled by hand. Its low operational rev range also means fewer combustion events occur when the engine is idling or running under a normal load. Solidworks has saved Shepherd costs by allowing the company to quickly and accurately design the parts required for the engine. In the coming months the company hopes to use Solidworks' simulation functionality to determine whether the parts it are using will be able to withstand the forces of the torque produced from the engine. The HTO engine can be used in all types of cars, trucks, heavy earthmoving equipment and, if it is scaled up, in th

PI Alignment System Enables Accurate Positioning

The F-206.S Hexalign system can be used in complex, high-accuracy positioning and alignment tasks where independent, high-precision motion in six degrees of freedom is required. The six-axis alignment system from PI provides 6D motion with 33nm resolution and advanced alignment software for optics and photonics components. It includes an advanced parallel kinematics controller/driver featuring vectorised motion with arbitrary pivot-point capability, as well as an extensive software package. The parallel-kinematics design with a virtual pivot point and vector-based 6D motion-controller means that the F-206.S system differs from conventional stacked multiaxis positioners. Due to the reduced moving mass - only one common lightweight platform for all six actuators - the system can respond and settle much faster. It is also said to be considerably more compact and accurate than conventional multi-axis stage stacks. Its parallel-kinematics design and advanced, digital 6D controller minimis

Air Motor Provides Positioning For Bagging Machine

To complete its design of a system to bag-up meat and cheese and apply appropriate label information, packaging machine manufacturer Greydon used the Huco Dynatork piston air motor. The Greydon Bagaire Taped Bag Loader utilised the motor for efficient bag opening and filling, and also for code dating with inkjet or contact printers. The machine presents the bags by winding up a leader tape and pulling the bags up from the table. Shop air is used via an air amplifier to blow open the bag for manual filling by the operator, who simultaneously breaks the bag away from the tape. The Huco Dynatork motor advances the bags quickly and stops them precisely in exactly the same location for opening and printing. As it is available with an acetyl housing, this motor is able to withstand the most caustic acids and chlorinated sanitisers used in the food and pharmaceutical industries. In operation, air up to 100lb/in2 is supplied to each of three pistons in turn via an integral rotary valve. The

Oscilloscopes For High-Frequency Power Measurement

Yokogawa has revealed that the G4 power measurement option on its digital and mixed-signal oscilloscopes can be used to carry out high-frequency power measurements in switched-mode power supplies. These measurements can now be carried out with greater accuracy using a de-skew correction signal source, along with voltage and current probes, in conjunction with the G4 option. Although power management using an oscilloscope is fundamentally less accurate than using a digital power meter, it offers much higher bandwidth. It is particularly suitable for measuring high-frequency switching losses in switched-mode power supplies. It also provides a power management capability using a general-purpose product that has other uses - an option that may be more acceptable to users who are not ready to invest in a true power meter or have limited budgets for test equipment. The de-skew correction signal source is an accessory that is specifically designed to maximise the measurement accuracy of osc

Thyssenkrupp To Produce B-Pillars For Compact Cars

Thyssenkrupp Umformtechnik has received an order from a German automotive manufacturer to produce B-pillars for more than 100,000 cars annually by tailored tempering. Thyssenkrupp's tailored tempering process was developed on the basis of hot-forming technology. The safety-relevant components are to be used in compact cars. The use of hot forming in car manufacturing is currently on the increase, according to the company. The process permits weight savings of up to 30 per cent in car components. Hot forming uses special manganese-boron steels. The sheet material is heated to 880-950C and is then formed into a component and cooled rapidly in the die. This produces components with strengths of up to 1,500MPa. These strengths are higher than those produced even with the strongest steels used for cold stamping. The components are lighter because the high strength of the material means that they can be designed with thinner walls and without additional reinforcements. While convention

Access to the design features can be hidden to prevent operators from making changes to the project. Projects in Ion Vision are said to be quick and simple to set up. All definitions, such as aliases, alarms or trend variables, are done in tables, allowing the user to export and import data, search and replace values, sort through the definitions or make global changes using the Express Edit feature. Ion V

Torque Sensors Aid Tidal Turbine Development

Non-contact torque sensors from Sensor Technology are playing a key role in the development of commercial-scale in-stream tidal turbines produced by technology company Openhydro. The Irish company is using these sensors, which are based on surface acoustic wave (SAW) technology, to measure rotational speed and frictional forces in a simulator for the turbine bearings. Openhydro designs and manufactures marine turbines to generate renewable energy from tidal streams. The company aims to deploy farms of tidal turbines under the world's oceans, where they will generate electricity with no cost to the environment. This method of producing electricity is said to have many benefits. For instance, as the turbines are submerged, they are invisible and they produce no noise. In addition, since they are submerged at a considerable depth, they present no hazard to shipping. The tides are completely predictable, which means that the energy output of the turbines is equally as predictable.

Rittal Introduces Rain Canopies For Enclosures

Rittal has expanded its AE Compact Enclosure range with rain canopies to combat potential weather-related problems. Although most of the company's AE Compact Enclosure range is rated to IP66, it was not designed for outdoor use. The introduction of stainless-steel models improved the protection against moisture and airborne contaminants. Following requests for a fully weatherproof version, Rittal introduced a series of rain canopies for the enclosures. Made from 1.4301 stainless steel, the canopies provide water run-off to the rear. They cover the join between the door and the enclosure itself, preventing water build-up on the seal and the possible reduction in effectiveness following freezing during sub-zero temperature periods. To prevent wind-driven rain from collecting, the canopies also cover the sides and rear of the enclosure at the top. A secondary function of the canopies is to shield the top of the enclosure from direct sunlight, thus reducing the solar temperature gain

Metalflex Hose Transfers Corrosive Media

The C Flex stainless-steel flexible hose from Metalflex Industrial Supplies can transfer a variety of media including corrosive liquids and gases. The hose is said to save space by reducing the bend radii that can be applied to it. This reduces the space envelope in which the hose is fitted. This convoluted hose core is manufactured from either 321 or 316 stainless steel. The convolutions are of closer pitch than standard cores and therefore have more flexibility, according to the company. Bend radii can be reduced by up to 25 per cent, thus saving space for the installer. The hose core can be used at working pressures of up to 10bar, which can be increased by covering the core in either a single or double metal braid cover. A double-braided hose can operate at pressures up to 275bar. The braiding, available in 304 or 316 stainless steel, also offers protection from external environmental conditions. For additional protection against corrosion, overbraids can also be supplied in Mo

Speed Switch For Refinery Or Gas-Plant Vehicles

The new Revguard speed switch from Chalwyn , an AMOT company, is suitable for vehicles working in refineries or gas plants. The new speed switch continuously monitors engine revolutions per minute (rev/min) and, should the engine rev/min exceed a preset limit, transmits a signal to close the air intake shut-off valve to stop an over-speeding diesel engine. Used on vehicles and stationary engines in the harsh Canadian climate, the compact and durable switches work with both 12V or 24V power and with a choice of speed input options. Encapsulated against fuel, moisture and dirt, they have a -30C to +75C operating temperature range. Engine speed is monitored either via a magnetic pick-up mounted on the engine's flywheel housing or a pulse signal from the alternator. Having automatic reset, a local trip indicator, screw terminals to facilitate installation and an aluminium frame for ruggedness, they are compatible with Chalwyn energised-to-stop SVX valves or an air pressure system com

Transformer Ohmmeter Features Fast Test Technology

Megger's new MTO210 transformer ohmmeter is suitable for measuring the DC resistance of magnetic winding and for checking the operation of on-load tap changers. Incorporating patented Fast Test technology, the MTO210 is said to make it easy to measure the DC resistance of all types of magnetic winding rapidly, safely and accurately. The Fast Test technology has been specifically developed to stabilise the test current in the shortest possible time, thereby reducing test times. Further time-saving features include dual-channel operation, which allows the resistances of transformer primary and secondary windings to be measured simultaneously, and bi-directional current output capabilities that allow users to take advantage of any existing magnetisation in the winding core to aid rapid current stabilisation. When used to check the contact resistance of make-before-break tap changes and voltage regulators, the MTO210 provides a fast indication of pitted or misaligned contacts. As a f

PRT Modules Are Ready To Install For Wind Turbines

The Iglidur PRT modules provide a ready-to-install solution for applications such as in semiconductor and cleanroom applications, assembly lines, wind turbines, production facilities and robots. The Igus slewing ring uses two self-lubricating, low-friction polymer sliding elements in place of the ball bearings - a cost-effective, low noise and highly wear resistant solution that is maintenance free. All housing parts are made of aluminium and use stainless-steel screws. The polymer elements contain solid lubricant so it does not require additional lubrication. The polymer also makes it resistant to chemical aggressors and features moisture absorption and good vibration-dampening properties. The Iglidur PRT slewing ring bearing system is available in a range of sizes, with outside diameters of 20, 30, 60, 100, 200 and 300mm.

SKF Supplies Oil And Wiper Seals For Motorcycles

SKF has won a contract to supply ZF Sachs Italy with 140,000 oil and wiper seals each year, to be used on the forks of high-performance motorcycles. SKF developed a new material to meet the specific requirements of ZF Sachs, featuring a special formulation that allows the seals to provide long-lasting self lubrication during operation. The seals eliminate stick and slip effects to enable high oil retention and prevent contamination from dirt and dust. Laboratory tests proved that the SKF seals could reduce friction by more than 20 per cent in comparison to competing products. As the rider is in direct connection with the front suspension system through the handlebar, the smoothness of the fork movement is said to be highly perceptible. In particular, pilots experienced an improved degree of smoothness that resulted in more accurate and comfortable riding during field tests with the SKF seals.

Procter Launches Modular Machine Guarding System

Procter 's Angel modular machine guarding system is suitable for factories applying lean manufacturing principles where there is often a need to rearrange the production facility to eliminate waste. The Angel system is offered with a range of standard components, although customised components can also be specified for delivery in a matter of days. The system is designed to be attractive and to enhance the visual appearance of the working environment. The company claims that, unlike other perimeter guarding systems, Angel provides complete design freedom in that guarding can be configured to suit any machine or factory layout. This is because the fencing panels can be manufactured to any size and the use of round posts means that panels can be fixed at any angle - not just straight or at right angles. Patented Universal Brackets enable multiple panels to be attached to a single post, which gives greater scope for creating the ideal guarding configuration or combination of guardin
