Electrostatic voltage sensor

The new TREK Model 875 electrostatic voltage sensor is designed for in-line monitoring of electrostatic charge build-up, which if left unchecked disrupts manufacturing processes and/or causes product degradation and early life failure of semiconductors and other charge-sensitive components. Manufacturers of electrostatic-sensitive devices can monitor production lines and other manufacturing processes in real time, enabling process adjustments. Model 875 features a measurement probe with automatic calibration technology, which maintains accuracy and speed even as the distance between the non-contacting probe and the monitored surface changes, unlike measurement technologies that require fixed-probe-to-surface spacing. Designed with DIN packaging, the sensor’s enclosure mounts on a 35-mm DIN rail. Other features include a voltage measurement range of ??500 VDC or peak AC, accuracy of ??0.5 percent, speed of 25 ms, and low noise of 2.5 percent of full scale. Buffered output voltage and current monitors (4???20 mA) are provided for remote monitoring and alarm purposes. The unit is powered by 24 VDC.
