CONTRINEX New Fiber-Optic Amplifier With Alphanumeric Display

Advantages Of Numeric Displays
Fiber-Optic Amplifiers are an integral part of many application areas. They have developed from what were originally simple devices into complex multi-functional switches packed with all kinds of features. One of these features is the numeric display, which is primarily used for visualizing the signal received and allows the device to be adjusted not only by instinct, but according to a reproducible measured value. This results in considerable advantages, particularly in critical applications.

Problems Of Conventional Devices
In general, the use of numeric displays is not just limited to visualizing the value of the signal received. Conventional high-end devices also allow excess gain, minima and maxima, timer and counter values to be displayed. Although this is useful, its practical use is fairly confusing. Granted, there is no shortage of operating instructions describing the extensive functions in detail. But who wants to study voluminous and sometimes…

Kepco BOP Models For Driving Inductive Loads

Kepco has announced the availability of its 200W and 400W bipolar operational power supply (BOP) models optimised for driving inductive loads. The modified BOP units are designed to operate in a stable manner in current or current limit mode for loads up to 1 Henry. They are also stable with any R-L series load combination.

All specifications of the unit in voltage mode are unchanged from the standard model. In current mode the bandwidth of the BOP is reduced modestly. Correspondingly, the rise-and-fall time of the unit is increased (model dependent). Further, it is possible to reduce the bandwidth in current mode, in a predictable way, using one customer-installed component on the rear programming connector of the BOP.

This option makes the BOP more suitable for a variety of applications such as motor testing, testing of magnetic components (coils, speakers, and so on), industrial applications with inductive loads, driving CRT coils, cryogenic applications and powering correcting magne…

MAX11040 Simultaneous-Sampling ADC Launched

Maxim Integrated Products has introduced the MAX11040 four-channel 24-bit simultaneous-sampling ADC. Developed to enable simplicity in system design, up to eight MAX11040 devices can be daisy-chained to provide a sampling capacity of up to 32 channels. The MAX11040 achieves this high capacity and scalability with a cascadable SPI/QSPI/Microwire interface, which eliminates the complexity of using individual chip-select inputs to control each ADC.

Because all eight MAX11040 devices can be accessed using only a single chip-select input, from the host processor's point of view, the control logic remains the same regardless if there are only four or as many as 32 channels. The MAX11040 provides compensation for phase shifts caused by resistor dividers, transformers, or filters at the analogue inputs through a programmable delay of 0-333 microseconds.

Together with a minimum of 90dB of SINAD and 91dB of SFDR, these features make the MAX11040 ideal for industrial power-grid protection equi…

Bulte Launches Self-Locking Nylon Nuts

Bulte Plastics has launched a series of plastic self-locking nuts. The lock nuts are suitable for applications that require extra security as they eliminate backlash without sacrificing efficiency. The company said this type of nut is more effective than standard hex nuts because it includes a no-threaded part that closes around the thread, creating a lock between the two threads.

Self-locking nuts are being used as a secure fastening nut for joining many kinds of parts. They are manufactured from natural Polyamide 6.6 that, when combined with steel screws, provides low drag torque and smooth operation throughout the life of the assembly (preferably not reusable). They also save weight over the conventional steel/nylon lock nuts.

The cost-effective plastic nuts are used in a variety of industrial applications, including: electronic and electrical equipment; construction; furniture; and medical industries; which require properties such as strength, corrosion resistance, oil resistance, l…

Stallion 3D Enables 3D CFD Analysis

Hanley Innovations has announced the availability of Stallion 3D, an all-in-one 3D compressible flow analysis software package for Windows XP/Vista PCs. Stallion 3D allows users to enter single or multiple CAD drawings (saved in the .stl file format) into the program for a 3D computational fluid dynamics (CFD) analysis. In addition, components such as wings, cylindrical shapes and closed bodies can be added to the analysis using the built-in geometry engine.

Users can position and rotate any of the components to match a desired test setup. The built-in pre-processor automatically detects the immersed boundaries and generates a Cartesian grid for the entire flow field. Users are not required to explicitly identify the components or their locations during the grid-generation process. The cut cell approach at the boundary is not used in Stallion 3D. Boundary conditions are satisfied using a novel ghost cell method that supports first, second or higher order flow solvers.

The scheme is unst…

Compair Compressor Uses Variable-Speed Motor

Airchannel has installed a Compair L132 SR rotary screw compressor at Potters Ballotini to meet new compressed-air requirements. Potters Ballotini recently installed a new bagging line at its Barnsley production facility to handle increased volumes and, as a result, air consumption increased from 400 CFM to 800 CFM. To meet this need, and to maximise efficiency, a new compressed-air solution was required.

As the appointed service provider to Potters Ballotini, a key challenge for Airchannel was to align the fitting of the new compressor in conjunction with the arrival of the bagging equipment from Italy to ensure there was no loss of production. From initial consultation to final installation, the project took less than three months.

The Compair L132 SR recommended by Airchannel uses a variable-speed motor, which allows air supply to match the varying production demands. Additional benefits include more air on demand, reduced noise and a smaller footprint. A Domnick Hunter dryer was inc…

Newport Spectra-Physics Expands Hippo Laser Family

Newport Corporation's Spectra-Physics Lasers Division has added the Hippo 532-14 to its Hippo family of Q-switched diode-pumped solid-state (DPSS) industrial lasers. The Hippo 532-14 provides 14W of 532nm output at 100kHz with a short pulse width of less than 30ns.

Used for solar thin-film scribing applications, the laser is suitable for the high-speed, multi-beam scribing of P2 and P3 layers in thin-film a-Si and CdTe photovoltaic structures. Scribe speeds in excess of 12m/s have been achieved on tandem-junction a-Si P2 layers with isolation lines 65 microns wide and 2.5 microns deep. Features of the Hippo 532-14 include its short pulse width (less than 30ns at 100kHz) and high peak power (up to 16kW at 50kHz). Both help to reduce undesired thermal effects such as heat-affected zones, material recast and the micro-cracking of a substrate.

The pulse-to-pulse stability of the Hippo 532-14 at higher pulse repetition rates (up to 200kHz) translates to good scribe consistency at high pr…

Precision Micro Invests In Laser Direct Imaging

Atlas Compressor Aids Norfolk Waterway De-Silting

An Atlas Copco compressor is at the heart of an aeration system that is being used to de-silt the Denver Sluice on the River Great Ouse, near Downham Market in Norfolk. The system is using compressed air to agitate the water and overcome the build-up of silt against the tidal doors that protect the river's guillotine gates. The sluice controls the water levels over parts of the fens and prevents high tides from flooding low-lying areas.

Over the past couple of years, the Environment Agency has had to dredge up to 4m of silt from in front of the gates and downstream of Denver Lock, because only a limited amount of water had been allowed to flow from the three 'eyes' of the sluice as a result of a prolonged period of dry weather. The decision to bring the 'eyes', which include the upstream guillotine gates, back into full service was hampered by the inability to move the silted-up tidal doors (mitre gate type) protecting them.

Rob Barker, project manager from the Envir…

MPS 32 Tool Changer Adds 40mm To Robot Arm

The MPS 32 from Staubli's connectors division provides efficient and secure tool changes for all types of robot arms, reducing the need for investment in additional robots. Its compact size minimises any loss of daylight and adds 40mm to the robot arm. Increasing the utilisation and productivity of automated manufacturing cells frequently requires several operations to be completed by robots, all within the production cycle time.

The end of arm tools required during the cycle can range from drilling or grinding heads to grippers or gauges. Additional operations usually require additional robots; but with the facility to quickly and automatically change the tools on a robot arm, the need for a second or even third robot is eliminated, reducing the capital investment required, improving payback and often reducing the overall cell footprint. Staubli's range of automatic tool changers are specifically designed for these types of applications and the introduction of the MPS 32 exten…

RDP Introduces SD Series Of Amplifiers

RDP Electronics has developed a range of IP65-rated inline signal-conditioning amplifiers that are suitable for mounting close to transducers in wet and grimy locations. For instance, the amplifiers are suitable for the conditions experienced on machines used in many process industries. Signal conditioning is required to boost or convert transducer output to a level and format for monitoring or data-logging purposes.

As it is important to ensure that the connecting low-voltage cable is kept as short as possible for a better-quality signal and noise immunity, the amplifier needs to be mounted close to the transducer. Thanks to the IP65 design utilising a compact, robust die-cast aluminium housing, also providing interference screening from electrical noise, the SD series of amplifiers can be located near to the measurement position in situations that may be wet, dusty or dirty.

RDP amplifiers are available for both DC or mains-supply input and are suitable for use with a range of LVDT tr…

Phantom v640 provides detailed high-speed images

Vision Research has introduced the Phantom v640 Cinemag camera, for industrial, military and research and development applications that demand ultra high-speed imagery with maximum detail. It offers a recording speed of more than 1400 fps at its full resolution of 2560 x 1600 pixels. For higher frame-rates, users can reduce the camera's resolution, increasing the speed. At a reduced resolution, the Phantom v640 offers a maximum frame rate of 300,000 fps.

This camera can also record at more traditional frame rates for normal use - as low as 10 fps. For example, when recording at 1920 x 1080, users can achieve frame rates of 10 fps, increasing to more than 2700. At maximum resolution of 2500 x 1600, the wide aspect of the Phantom v640's CMOS imaging sensor allows users to keep a moving target in the frame for a longer time than possible with traditional square imaging sensors. The camera's peak quantum efficiency (QE) has been improved to 60 per cent.

The improvement in QE is …
