Rtd operating principle
WebEach signal conditioner must be perfectly adapted to the sensor with which it will be used. Sensors have vastly different requirements based on their operating principles, which the conditioner must be adapted to. For example, a strain gage (aka strain gauge) signal conditioner must provide excitation voltage to the strain gage sensor. And ... WebDifference between Thermistor and Resistance Temperature Detectors (RTD) Both devices work on the same principle that a constant current flowing through the resistor, and its changing resistance due to change in temperature, is measured as a voltage drop across it.
