Trek’s new Electrostatic Voltage Sensor, Model 875, is designed for in-line monitoring of electrostatic charge build-up, which if left unchecked would disrupt manufacturing processes and/or cause product degradation and early life failure of semiconductors and other charge-sensitive components. Used to monitor static charge levels within manufacturing equipment such as conveyors, handlers, and other tools. Trek’s Model 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 V DC 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 unit is powered by +24 V DC and is housed in a standard DIN package to enable standardized mounting.
