RTD (Resistance Temperature Detector) - Honest Well
www.honest-well.com.twRTD (Resistance Temperature Detector) RTD (Resistance Temperature Detector) are sensors used to measure temperature by correlating the resistance of the RTD element with temperature. Most RTD elements consist of a length of fine coiled wire
Measuring Temperature with RTDs – A Tutorial
newton.ex.ac.ukA resistance-temperature detector (RTD) is a temperature sensing device whose resistance increases with temperature. An RTD consists of a wire coil or deposited film of pure metal. RTDs can be made of different metals and have different resistances, but the most popular RTD is platinum and has a nominal resistance of 100ÊΩ at 0°ÊC.

www.chromalox.comA temperature sensor, usually a thermocouple or RTD (resistance temperature detector), measures the temperature inside the furnace. The output of the temperature sensor is fed to a temperature controller such as the Chromalox 2104. The controller compares the temperature to the setpoint and outputs a control signal to the SCR power regulator.
