RTD Types

2 Wire RTD

Using the 2-wire method, the two wires that provide the RTD with its excitation current and the two wires across which the RTD voltage is measured are the same.

 

3 Wire RTD

In a three wire RTD one of the wires is connected to one side of the temperature element and the remaining two wires are connected to the other side of the element.

4 Wire RTD

The optimum form of connection for RTDs is a four-wire circuit. It removes the error caused by mismatched resistance of the lead wires.

What is an RTD?

Resistance Temperature Detectors or resistive thermal devices (RTDs), are temperature sensors that exploit the predictable change in electrical resistance some materials with changing temperature.
