Rtd Transmitter Circuit Diagram. Rtd circuits work by sending a known amount of current through an rtd sensor and then measuring the voltage drop across that resistor at the given temperature. The best configuration for a specific application depends on a number of factors however the sensor configuration must match with transmitter otherwise leadwire resistance cancellation circuitry.
From the lead wire reacting with the sensor excitation. 3 wire rtd wiring diagram in this circuit there are three leads coming from the rtd instead of two. Rtd circuits work by sending a known amount of current through an rtd sensor and then measuring the voltage drop across that resistor at the given temperature.
Finally the signal conditioning path for the rtd system will be covered with application circuits from sensor to microcontroller.
