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 20mA) 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.
