Insulate or terminate the unused white lead in a manner that prevents shorting to the ground.

RTDs with 3-wire connections are the most used of the 3 solutions presented. The presence of an additional wire in relation to the above system is precisely to 

RTD wiring configurations. There are three types of wire configurations, 2 wire, 3 wire, and 4 wire, that are commonly used in RTD sensing circuits.

return wires only), and over- and under-range detection and indication. IMPORTANT The module accepts input from RTDs with up to 3 wires. If your application requires a 4-wire RTD, one of the two lead compensation wires is not used, and the RTD is treated like a 3-wire sensor. The third wire provides lead wire compensation.

Rtd wiring diagram R1, r2, and r3 are fixed l3 resistors; Connect the positive extension wire to the positive rtd wire and the negative extension wire to the negative. The 2 wire rtd configuration is the simplest among rtd circuit designs. In this uncompensated circuit, lead resistance l1 and l2 add directly to rt. Get 3 Wire Rtd Wiring Diagram

Fluke data acquisition models are designed to measure RTD inputs (Resistance Temperature. Detector) or PRT probes with a 4-wire connection. A 4-wire.

3 Wire RTD Wiring Diagram. In this circuit there are three leads coming from the RTD instead of two. L1 and L3 carry the measuring current while L2 acts only as a potential lead. No current flows through it while the bridge is in balance.Since L1 and L3 are in separate arms of the bridge,resistance is canceled.

In this type of configuration three lead wires would come from the RTD. So in this three-wire configuration, two wires would carry the measuring

Two, Three and Four wire measurement techniques have been developed for measuring accurately the resistance of resistive temperature detectors (RTD).

Ratio-Metric 2-Wire RTD application Advantage: •Very simple RTD connection. •IDAC generates the sensor excitation and the reference voltage. •Noise and drift of the Ref voltage are correlated and therefore canceled. •Only one current source no mismatch. •Up to 7 RTDs are possible Disadvantage: Voltage drop across the line resistance.

4-wire construction is used primarily in the laboratory where close accuracy is required. In a 4 wire RTD the actual resistance of the lead wires can be determined and removed from the sensor measurement. The 4-wire circuit is a true 4-wire bridge, which works by using wires 1 & 4 to power the circuit and wires 2 & 3 to read.
