Resistance Temperature Difference. Used in thermocouple technology.
one way is to use RTD sensor put inside the motor windings. The RTD sensor is connected to an electronic thermal overload relay. This type of relay can provide running temperature of the motor, on the electronic thermal over load relay display panel. RTD sensor is a wire wound resistor that changes resistance depending on the temperature

The sensor can either be an RTD, resistive thermal device or a thermocouple. In the case of RTD, the resistance of the device changes with the temperature. This resistive value is sent to a calibrated meter or gauge. A RTD device is far more accurate than a thermocouple. Plus or minus .1 of 1%. In the case of a thermocouple a small voltage is created by the device which varies with the temperature. This is sent to the reading device or gauge. Plus or minus 2 0r 3 degrees.
for temperature sensing i will suggest a RTD or A THermocouple. for temperature sensing i will suggest a RTD or A THermocouple.
RTD stands for resistance temperature difference.There are three types of RTD i.e 2 wire,3 wire and 4 wire.A PT-100 RTD is generally used in industry to determine temperature.It`s one end sense temperature and hence due to this resistance of metal changes.This change in resistance is calculated and temperature is calculated through a formula: R=r(1+@^t) where ^ = .03692

Resistance Temperature Device
a temperature control system relies upon a controller, which accepts a temperature sensor such as a thermocouple or RTD as input. It compares the actual temperature to the desired control temperature, or setpoint, and provides an output to a control element. The controller is one part of the entire control system. these are found in the interior climate control system, and in engine cooling system.
It depends on which type of sensor you are referring to. Say if its a temp sensor like RTD, an open sensor will show a very large value of resistance and failed sensor may show any resistance value(and not according to a chart value corresponding to the temp for type of RTD). If its a pressure sensor, its output values would be outside the measurement range.
