Electrostatic voltmeter

Click here to enlarge image

Model 542 electrostatic voltmeter provides DC, stable (0 drift) measurement of electrostatic voltage in the range of 0 to ±20 kV using a noncontacting chopper-stabilized remote-positionable sensor probe. When operated online, the unit can identify the failure or ineffectiveness of electrostatic discharge (ESD) countermeasure equipment or techniques by providing audible and visual indications of voltage build-up beyond user-adjustable positive and negative limits. A 20¥4 alphanumeric LCD screen displays the present measured voltage, the positive peak voltage value, the negative peak voltage value and additional menu information.

Piezoresistive PCL sensors offer measurement from 5 mbar to 75 mbar full-scale (FS). According to the manufacturer, offset errors, warm-up and long-term stability, and position sensitivity are reduced when compared to conventional compensation methods. The sensor uses a silicon, micro-machined, stress concentration enhanced structure to provide a linear output to measured pressure. The output of the device is ratiometric to the supply voltage, and operation from any DC supply voltage of up to +16V is acceptable.
