Trek 875


Electrostatic Voltage Sensor Designed for Inline Monitoring of Electrostatic Charge Build-Up

The Trek® 875 electrostatic voltage sensor is used to monitor static charge levels within manufacturing equipment such as conveyors, handlers, and other tools. The Trek® 875 features an automatic calibration technique to maintain high accuracy and speed over wide variations of the spacing between the non-contacting measurement probe and the surface under test. Other features include a voltage measurement range of ±500 VDC or peak AC, accuracy of ±0.5%, speed of 25 ms, and low noise of 1% rms of full-scale. Buffered output voltage and current monitors (4 to 20 mA) are provided for remote monitoring and alarm purposes. The instrument is powered by +24 VDC and is housed in a standard DIN package to enable standardized mounting.


  • Accuracy is independent of probe-to-measured surface spacing
  • 4 to 20 mA current monitor
  • Voltage monitor with an accuracy better than ±0.5% of full-scale


  • Select from two available probe types, side view and 45° angle
  • Mount the enclosure on a 35 mm DIN rail
  • Use TTL digital enable input and TTL fault warning flag output


Messbereich: 0 to ±500 V
