Pt100 Temperature Sensor Connection Diagram. The addition of a third wire connected to one side of the measuring element helps to compensate for the lead resistance. Where do those wires go pt100 1.
Because a very small change in resistance happens with each degree in temperature the. A pt100 normally has 3 wires. Pt100 temperature sensor wiring diagram.
When wiring with two wires first jumper across a1 and b1and a2 and b2 respectively then connect pt100 sensors and to the rtd module according to the following diagram on the left.
It is very important that each of the three wires used in the measuring circuit are equal in terms of both conductor size and length. It is very important that each of the three wires used in the measuring circuit are equal in terms of both conductor size and length. A1b1 a2b2 and c1c2. 3 wire pt100 rtd sensor wiring system.
