    Tips: Differences between sheath RTD sensor and general thermal resistance
    The sheath RTD sensor is the thermal resistance that is soldered and sealed thermistor temperature-sensing element in the sheath wire, which consists of metal casing pipe, insulation material and metal wires. The metal casing material of sheath wire is usually stainless steel. The lead wire is usually copper conductor or silver conductor, and the insulation material is usually magnesium oxide.
    There are many characteristics of sheath RTD sensor compared with the general thermal resistance.

    1. The external diameter of thermistor can be small, so its time constant is small and reaction speed is fast.
    2. It has bendability and is suitable for temperature measurement of complex structure and small equipment.
    3. It has good vibration resistance and impact resistance.
    4. It has long service life.

    In this video, ATO will show you how to connect RTD sensor to temperature controller and how to use RTD sensor to measure water temperature.

    Existing reviews of RTD Sensor, Pt100, Sheath, 3 Wire
    Wiring Complexity
    The 3-wire configuration, while beneficial for accuracy, can be a bit more complex to set up and troubleshoot compared to simpler 2-wire sensors.

    Precise RTD sensor
    I ordered this RTD sensor for a temperature controller. It was easy to connect and worked great. It is accurate and so far it is water proof. I would buy it again.

    ATO Responded
    Yes, you only need to specify the required specifications/dimensions of the Pt100, 3wire RTD sensor you buy.
    3 wire RTD sensor Pt100
    The accuracy of PT100 RTD sensor is good, and the error at 170℃ is about 0.2℃. So it will continue to be used with no problem.
