The Trek Model P0865 is a DC stable, precision electrostatic voltmeter for making noncontacting surface voltage measurements in the range of 0 to ±10 kV DC or peak AC.
Research and industrial applications include charge accumulation monitoring of the LCD production processes, monitoring surface potentials in the electrostatic painting process, research and development in the electrophotographic process, and measuring electrostatic potentials on polymers, rubber, fabrics, and paper.
The Model P0865 employs a field-nulling technique for noncontacting voltage measurement that achieves DC stability and high accuracy even if the probe-to-surface spacing changes. This permits measurements of either stationary or moving surfaces without the need to establish fixed spacing to maintain accuracy.
The Model P0865 patented probe design eliminates the need for close tolerance components. This significantly improves noise and drift performance, both in the presence of contaminating particulates and under conditions of high humidity and wide temperature ranges.
A precision voltage monitor provides a low-voltage replica of the measured electrostatic potential for monitoring purposes, or for use as a feedback signal in a closed-loop system.
The Model 3450 probe assembly includes a sensitive electrode and preamplifier, which is driven to the same potential as the measured value to eliminate arcing there between. A three (3) meter cable permits remote probe positioning. The Model P0865 can be operated on a bench top or, with optional hardware, in a standard 19-inch rack.
