    Tips: Connection methods of Pt100 RTD sensor
    Pt100 RTD sensor usually has two-wire and three-wire connection methods. The two-wire connection is to connect a wire to both ends of thermistor. This connection method is simple with low cost. But it will bring additional error as the lead resistance becomes one arm of the bridge. Although with each change of 10 degrees centigrade, PT100 only changes 0.39 ohms. But the lead wire of industrial field thermistor is usually long and the lead resistance will certainly affect the result of the measurement. Therefore, Pt100 of two-wire connection is only suitable for short distance application. It is necessary to use three-wire connection in the application of long distance. The three-wire connection is to lead one line at one end of thermistor and the other two lines are led at another end. When the thermistor matches with the measuring bridge, lead resistance is connected to two arm of the bridge circuit, which eliminates the influence of the lead resistance and improves the measurement accuracy.

    In this video, ATO will show you how to use RTD PT100 with transmitter and temperature controller to measure temperature.

    Existing reviews of RTD Sensor with transmitter, Pt100, 2 Wire
    The sensor works just as the my original one did!
    I lost my original RTD sensor, but this set pf RTD sensor with transmitter is a perfect replacement. The sensor works just as the original did, and the sensor is accurate. Price is excellent as well.
