Web the temperature sensor pt100 is widely used for temperature measurement below 650 °c due to its small size, high accuracy and good stability. Pt100 3 Wire Temperature Sensor Circuit Diagram A Pt100 temperature sensor is a type of resistance temperature detector (RTD) that uses a platinum element to measure temperature. 011°c resolution. A Pt1000 measuring element in class A also offers good measurement accuracies in a 2-wire connection and represents an economical alternative to 3- or 4-wire connections for machine building. This is one of the ideal choices for measuring higher temperature readings which the other temperature sensors such as LM35 and others. Cn0287 Circuit Note Analog Devices. With a temperature sensor with a Pt100 sensor element, we recommend that you install the 3-wire circuit. Temperature Measurement Accuracy 0. 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. Copper / Constantan.
