Measuring Temperature with RTDs – A Tutorial
If you are using lead lengths greater than 10 ft, you will probably need to compensate for this lead resistance. The preferred RTD measurement method is to use a four-wire RTD. One pair of wires carries the current through the RTD; the other pair senses the voltage across the RTD. Because only negligible current flows through the sensing wires ...

It is still a quarter bridge circuit, since only one of the four bridge resistors has been replaced by the RTD. However, one of the lead wires has been placed on the R 2 leg of the bridge instead of the R 3 leg.. To analyze this circuit, assume that R 1 = R 4, and R 2 = R 3 initially, when the bridge is balanced.Recall the general formula for a Wheatstone bridge:

Temperature Sensor : Various Types with Examples
Another type of sensor is a thermistor temperature sensor, which is relatively inexpensive, adaptable, and easy to use. It changes its resistance when the temperature changes like RTD sensor. Thermistors are made from manganese and oxides of nickel, which make them susceptible to damages. So, these materials are called ceramic materials.
