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.
