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
