The Review of: Replacement PT1000 Temperature Sensor 3 Wire Durable Replace Parts Accessories 12V 24V for 2kW 5kW Diesel Parking Heater Review

A PT1000 temperature sensor is a type of resistance temperature detector (RTD) commonly used for precise temperature measurements. Let’s break down the details:

  1. PT1000 Sensor Basics:

    • The PT1000 stands for a Platinum RTD with a resistance of 1000 ohms at 0°C.
    • Unlike traditional PT100 sensors, PT1000 sensors have a higher nominal resistance, which compensates for added wire resistance errors.
    • They are known for their accuracy, stability, and repeatability.
  2. Wiring Configuration:

    • The PT1000 sensor typically uses a 3-wire configuration.
    • Two wires connect to either side of the platinum resistor (as expected).
    • The third wire is also connected to one end of the PT1000.
    • If your RTD amplifier supports 3-wire sensors, it will drive the resistor with the first two wires and measure voltage differences to account for any wire voltage drop.
    • If your RTD amplifier only supports 2-wire sensors, simply leave the third wire disconnected.
  3. Temperature Range:

    • The PT1000 sensor you mentioned is designed for a temperature range of -90°C to 500°C (or -70°C to 260°C).
  4. Applications:

    • PT1000 sensors find applications in various fields, including refrigeration, heating, ventilation, automotive, and machine building.
    • They are especially useful in scenarios where accuracy and minimal self-heating are critical.
