MALVERN, PENNSYLVANIA - June 3, 2005 - Vishay Intertechnology, Inc. (NYSE: VSH) announces the release of Vishay Transducers GLT Web Tension Systems. Designed to meet the needs of paper, film, foil converting, and printing equipment manufacturers, the new, low-tension GLT Web Tension Systems precisely measure winding, rewinding, slitting, coating, laminating, and printing zone to ensure premium process performance.
GLT Web Tension Systems combine an easy-to-install Vishay Transducers PS-1010T web tension transmitter and precision Vishay BLH Model GLT transducers to provide reliable, repeatable, web tension measurement at a reasonable price.
The PS-1010T web tension transmitter is a signal conditioner/amplifier for single-zone web tension measurement that eliminates low- tension signal drift. The galvanically isolated analog output signal accurately tracks web tension force signals for precise brake/clutch control or remote panel meter display. Features include compact, lightweight DIN rail Snap Track installation; independent zero and span adjustments; galvanically isolated 0 V to 10 V, 4 mA to 20 mA output signals; and low power (24 VDC @ 125 mA). It filters electrical noise caused by AC drives, servo motors, and switching devices.
GLT transducers eliminate drift and frequent recalibration problems encountered with conventional half-bridge, semiconductor type load cells. In fact, GLT specifications are twice as accurate as those of competitively priced semiconductor load cells. Full Wheatstone-Bridge, temperature-compensated, SR-4 strain gage construction provides precision performance with high signal stability and negligible drift. GLT outline dimensions are identical to existing equipment, thereby enabling simple, drop-in replacement. Factory calibration with matching output signals significantly simplifies installation while ensuring long-term calibration reliability.
GLT transducers are available in 20-lb, 50-lb, 100-lb, 200-lb, and 500-lb ratings, and operate over a temperature range of -40 degrees C to +105 degrees C. Rated output is 2.0 mV/V +/-0.25%, while non-linearity and repeatability are 0.25% and 0.02% RO respectively.
While ideally suited for a very wide range of installations, GLT Systems perform superbly in applications with high roll weight/low tension ratios and/or wide rangeability requirements.
