Rtd Pt100 3 Wire Wiring Diagram

rtd pt100 3 wire wiring diagram

The three wire configuration provides a compensation loop that can be used to The 3-wire circuit makes it possible to compensate for the line resistance both in its amount and also in its temperature variation.

It is called a PT because at 0 deg C it will measure ohms. 3.

3 Wire RTD Sensor

At ambient it will be around ohms. 4.

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 schematron.org L1 and L3 are in separate arms of the bridge,resistance is canceled. 3-Wire RTD with compensation Advantage: •IDAC generates the sensor excitation and the reference voltage. •Noise and drift of the Ref voltage are correlated and therefore canceled.

•Voltage drop across the line resistance are compensated. •Allows complete utilization of the input range, no offset caused by the RTD itself.

Disadvantage. The RTD wire is a pure material, typically platinum, nickel, or copper.

The material has an accurate resistance/temperature relationship which is used to provide an indication of temperature. As RTD elements are fragile, they are often housed in protective probes.
