rtd pt100 3 wire wiring diagram - What is a Wiring Diagram? A wiring diagram is a straightforward visual representation of the physical connections and physical layout of your electrical system or circuit. It shows how a electrical wires are interconnected which enable it to also show where fixtures and components may be coupled to the system.

Three-wire. Four-wire. Two-wire measurement: This is the most basic type of connection for an RTD device. It is used in very simple, cheap applications. They minimize cost at the expense of accuracy. The main problem with two wire measurement is that there is no accounting for the resistance, or even change of resistance in the sensing leads

of feet long. The 3-wire RTD uses 1 additional wire and the 4-wire RTD uses 2 additional wires to compensate for the wire resistance. Generally speaking, field devices have inputs for 3-wire sensors to provide sufficient compensation of the wire resistance. However, by "pulling" 3 wires to a 2-wire or 4-wire RTD you can achieve the same

3-Wire configuration. In the image above, an RTD, symbolized as Rpt, is connected with three wires with each wire having a resistance of R1, R2, and R3. The resistance as seen from wire 3 and wire 2 is Ω1 = R2 + Rpt + R3 and the resistance seen from wire 1 and 2 is Ω2 = R1 + R2. By subtracting Ω2 from Ω1 we get the final resistance of Ω1

RTD, as in a connection head, errors are negligible. 2-wire circuit Shown is a 2-wire RTD connected to a typical Eo Wheatstone bridge circuit. Es is the supply voltage; Eo is the output voltage; R1, R2, and R3 are fixed L3 resistors; and RT is the RTD. In this uncompensated circuit, lead resistance L1 and L2 add directly to RT. 3-wire circuit
