Test & Measurement
Test probes position sensor supplies exact measurements
Now available from Peak Test Services are a range of test probes which features a built-in position sensor system designed to provide an exact measurement of the distance travelled by the probe in contacting the test item. They are designed for measuring parameters such as pin lengths, component heights or the depth of drill holes in wire harnesses and connectors.
The PS21/G series incorporates a small integral potentiometer that is screwed together with the contact probe and receptacle.
When a voltage is applied, a 3-wire circuit acting as potential divider provides either a voltage or a resistance that is linearly proportional to the travel of the probe and can thus be used by the test system to provide a distance measurement.
