WebThe way a 3-wire RTD works is by pushing a fixed current through lead 1, then through the RTD element, and then back to the device through lead 2 or 3 but not both. There will be a certain voltage drop (due to Ohm's law) in each of these steps of the current path. The idea is that there is a certain voltage drop on lead 1 due to the resistance ... WebRTD Wiring Configurations- 2, 3 & 4 Wire. RTDs are used to measure the temperature of the process, bearings, and motor windings. RTD’s resistance changes with change in temperature and this is used in many applications to measure temperature. RTDs work generally with three RTD wiring configurations – 2- wire, 3- wire , and 4- wire.

RTD Wiring Overview

WebAn RTD works by using a basic principle; as the temperature of a metal increases, so does the resistance to the flow of electricity. An electrical current is passed through the sensor, the resistance element is used to measure the resistance of the current being passed through it. As the temperature of the resistance element increases the ... WebRTD probes can be found in either a 2, 3 or 4 wire configuration.
