Eaton Switchboards Assist In Flour Mill Upgrade

Switchboard supplier EMS has selected switchboards in Eaton 's Moeller Modan range to assist in the completion of an upgrade to a Heygates flour mill in Tring, Hertfordshire. The task of upgrading the electrical equipment in the mill posed two key challenges. The first was that the space available to accommodate the new switchboards was extremely limited. The second was that, as the mill operates continuously and downtime is costly, it was necessary for Heygates to be able to carry out maintenance and fault-finding work on, for example, individual motor starters, without shutting down the whole plant. EMS knew from its work on previous projects that switchboards from Eaton's Moeller Modan range would provide a complete and cost-effective solution to both problems. While the Modan switchboards are available in a variety of configurations, for this application the engineers chose the Modan W. Because Modan W uses withdrawable and removable plug-in units, function modules can be

Rotary Position Sensors Added To ST350 Series

Sensor Systems has added a range of Hall-effect rotary position sensors to its ST350 series. The company said the sensors simplify customer use by providing the CANbus outputs needed for new-generation control systems.

PK40 Pump Has No Seals, Glands Or Valves

Pump Engineering has announced that the Ponndorf PK40 compact double-head hose pump is now available. The Ponndorf PK40 high-pressure twin unit is capable of providing flows up to 15,000 litres/hr at pressures up to 15 bar. The versatile, self-priming, pumps offer the advantages of peristaltic pumping, which are particularly relevant to the food-processing and water-treatment industries. For example, shear-sensitive, delicate liquids or those containing solids remain unaffected by the pumping process. The absence of seals, glands and valves reduces the likelihood of component failure and resulting downtime, sometimes associated with demanding pumping applications, such as those involving abrasives and other similar aggressive media. Cleaning and washing is also simplified because only the hose has contact with the process fluid, therefore quick and effective cleaning is achieved simply by flushing through the hose. The pump is fully reversible and is supplied with a selection of hos

Laser Welding Suits Precision-Welding Processes

Laser Lines has explained the key advantages of laser welding. Nylon welding processes are split into two categories: low-energy-density, and high-energy-density processes. Low-energy-density processes are those such as traditional arc and resistance welding technologies that rely on heat conduction through the material from a surface point to provide melting. High-energy-density processes using lasers create a heating filament, known as the keyhole, which penetrates the depth and offers 2D line heating, causing a highly efficient heat transfer into the weld joint. The key advantages of laser welding are a small heat-affected zone (HAZ), accurate control of heat input, and the ability to direct the beam precisely to the weld point. This means reduced thermal distortion, the ability to weld close to heat-sensitive parts, and precision welding capabilities. Major applications for sub-kilowatt lasers are in precision-welding and heat-sensitive welding processes, such as hermetic sealing

Ascent Now Automatically Ensures X-Robust Designs

Real Intent 's Ascent functional verification product now includes an automated solution to ensure X-robust designs, available through the Ascent Path-Based Verification (PBV) product. Explicit and implicit X sources (X assignments in RTL and non-resettable flops, respectively) in the designs can lead to many challenging issues for design verification, such as masking real design errors and causing RTL-to-netlist simulation mismatches. Depending on coding styles, simulation results can be X-pessimistic, which lead to unnecessary unknown values; or X-optimistic, which result in known values when they should have been unknown. Design and verification teams write properties to trap Xs or instrument two-value simulation with random initialisation to avoid X ambiguity in order to detect design errors. However, these approaches take a considerable amount of manual and computational resources without offering the complete confidence of X robustness. Ascent PBV offers a multi-faceted sol

Orchid Converts Bayer Pixel Data With Cyclone FPGA

Converting CMOS imager Bayer-pattern pixel data to RGB pixel data can be readily accomplished using low-cost FPGA technology devices. Pixels within modern CMOS image sensors are typically arranged in a Bayer colour pattern. Image data is scanned from left to right and from top to bottom. Each scanned raw pixel is actually a monochrome colour element, either red, green or blue. Inherent characteristics of the human eye make it advantageous to have twice as many green pixels as red or blue ones. To render a CMOS imager's output human-viewable, a conversion from the Bayer image-data format to an RGB image-data format is necessary. A common method of converting Bayer image data to RGB data is the bi-linear-interpolation method, in which a 3 x 3 Bayer-pixel matrix is mathematically combined into a single pixel with separate red, green and blue data-component values. Thus a 3 x 3 matrix of monochrome pixels is transformed into a single pixel with three component values. The mathematics

MCP4728 Quad DAC Features Non-Volatile EEPROM

Microchip has released the MCP4728 digital-to-analogue converter (DAC), a 12bit Quad DAC that includes non-volatile EEPROM, enabling the DAC's configuration to be loaded automatically during power-up. The on-board EEPROM, coupled with an internal voltage reference, four-channel architecture and rail-to-rail precision output amplifier, enables the MCP4728 DAC to reduce the size and component cost in a variety of battery powered and power-constrained applications. Through the integrated I2CTM serial interface, designers can configure the MCP4728 DAC's input codes, configuration bits and I2C address bits. This configuration information is stored in the non-volatile EEPROM and therefore retained after power is removed, making it available immediately after power is re-applied and reconfiguring the DAC during power-up. The architecture of the MCP4728 also allows each of the four channels to be individually shut down, thereby reducing power consumption to as low as 40nA, helping de

Linear Offers LTC3569 Synchronous Buck Regulator

Linear Technology 's LTC3569 is a triple-channel, high efficiency 3MHz synchronous buck regulator. It delivers 1.2A of continuous output current from one channel and 600mA from each of the other two channels. Using a constant frequency current-mode architecture, the LTC3569 operates from an input voltage range of 2.5 to 5.5V, making it ideal for single-cell Li-Ion/polymer or multicell alkaline/NiCad/NiMH applications. Each of the three output-voltages are independently programmable by lowering the feedback voltage of each channel from 800 to 425mV (in 25mV increments) by toggling the EN pin, enabling dynamic adjustment of each channel's output voltage. Additionally, each of the 600mA regulators can act as slave power stages to each other or to the 1.2A channel to support higher currents, providing additional design flexibility. The LTC3569's switching frequency can be programmed between 1 and 3MHz or set at 2.25MHz, enabling the designer to optimise efficiency while avoid

HDMI Active Enhances Viewing And Sound Quality

Chord has introduced the HDMI Active, which enhances picture and sound quality. This product features heavy gauge silver-plated oxygen-free signal conductors. Signal attenuation has been reduced with the use of 26AWG conductors. Overlapped foil shielding around all critical signal paths minimises crosstalk. Double outer foil and high-density braid combine to minimise the levels of external interference. The exciting aspect of the Chord HDMI Active is the inclusion of a high-frequency filter on all lengths. The filter reduces the intra/inter channel skew between the four pairs of TDMS signals. The HDMI Active cable improved all aspects of the picture in tests using Denon, Arcam, Yamaha and Playstation 3 DVD and Blu-ray players. When compared with the Chord HDMI Silver plus 1.3, the Chord Active produced a more detailed, dynamic and musically coherent sound. The improvement in performance was such that in tests, participants consistently chose a 15-metre Chord Active HDMI cable over a
