Thermocouple 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.
