Resistive Sensor Structure
Sep 27, 2018

Structure: consists of two basic parts: the resistance element and the brush. The motion of the brush relative to the resistance element can be linear motion, rotation and spiral motion, so the linear displacement or angular displacement can be converted into the resistance or voltage output with which it is a function.

The structure and material of the potentiometer

(1) resistance wire: constantan wire, platinum iridium alloy and kama wire, etc

(2) electric brush: metals such as silver, platinum iridium and platinum rhodium are commonly used

(3) skeleton: the commonly used materials are ceramic, phenolic resin, laminated rubber and other insulating materials. There are many structures of the skeleton, and rectangles are commonly used.
