Advanced Energy is now offering its Trek Model 875 Electrostatic Voltage Sensor which, unlike other electrostatic voltage sensors currently available, can perform electrostatic monitoring without touching the product being measured and is insensitive to distance (within the specified range).

Source: Advanced EnergyTrek Model 875 can monitor electrostatic charge in a continuously moving production process, for the manufacturing of many products including semiconductor devices, flat panel displays, textiles, packaging, electrophotography, pharmaceuticals and electronics — processes in which electrostatic charge buildup can disrupt the production process or cause significant damage to the product being manufactured.
Elisabeth Pederson, general manager of Advanced Energy's Trek product group explained that the Model 875 builds on the company's existing market experience with "field nulling" electrostatic voltmeters. “Customers that manufacture products in a moving production process will use various techniques to mitigate the buildup of harmful electrostatic charge. The Model 875 continuously measures the process, providing a real-time monitoring of charge build up. This allows the manufacturer to take swift action to significantly reduce the risk of field failure and process issues.”
Model 875 features several other advantages. It is packaged in an industry-standard 35 mm width DIN rail enclosure, which makes it easy to integrate with any manufacturing line. Further, Advanced Energy’s probe design automatically helps to alleviate particle contamination on the sensor through the continuous motion of its chopper-stabilized operation enabling it to maintain high accuracy and speed.
Model 875 has a measurement range of +/-500 V DC or Peak AC, speed of response of less than 25 mS, and an accuracy of +/- 0.5% of full-scale. Detailed technical specifications are available here.
