The Model RB-100 Linear Potentiometer Readout is designed to read Geokon’s range of Model 1500 Linear Potentiometers. The unit utilizes a high resolution, 4.5 digit LCD digital voltmeter with circuitry to power and read out the potentiometers. A three wire ratio-metric system is used to minimize errors caused by long lead lengths and varying temperatures. In use, a regulated voltage is applied to the ends of the potentiometer resistance element and the position of a wiper, that rides along the element, can be determined by the voltage measured at this point.
