4 wire rtd configuration temperature sensor. It should be noted that the circuit is very sensitive to the rtd lead resistance. A 4 wire rtd adds a fourth wire and works as a true bridge circuit.

A 4 wire rtd is the sensor of choice for laboratory applications where accuracy, precision, and repeatability are extremely important.

The bridge requires four connection wires, an external source. A 4 wire rtd is the sensor of choice for laboratory applications where accuracy, precision, and repeatability are extremely important. This 4 wire configuration allows constant compensation for any lead wire issue. •idac generates the sensor excitation and the reference voltage.
