Description of product


For precision temperature sensing, nothing beats a PT1000-S Waterproof 1m 30mm Stainless Steel Pole Probe Temperature Sensor. Resistance temperature detectors (RTDs) are temperature sensors that contain a resistor that changes resistance value as its temperature changes, basically a kind of thermistor.

In this sensor, the resistor is actually a small strip of Platinum with a resistance of 1000 ohms at 0°C, thus the name PT1000. Compared to most NTC/PTC thermistors, the PT type of RTD is much most stable and precise (but also more expensive). PT1000’s is useful to measure temperature in laboratory and industrial processes; and have developed a reputation for accuracy (better than thermocouples), repeatability, and stability.

This high-temperature PT1000 sensor is equipped with a 316L stainless steel shield (try saying that five times fast!) that is good for up to 550°C.

How does the sensor work?

  1. As the temperature in your application changes then the electrical resistance will also change. An increase in temperature will increase the resistance of the temperature sensor.
  2. The measurement is completed by your instrument by applying a small measurement voltage and utilizing a bridge type circuit.

PT1000 features

  1. Based on resistance measurement principles.
  2. Resistor material is Platinum with a value of 1000 ohm at temperature 0°C.
  3. Platinum has a positive resistance-temperature factor; resistance increases with rising temperature.
  4. Resistance variation is a function of temperature: 3.85Ω/°C nominal.
  5. High accuracy and stability compared to thermocouples, silicon-based temperature sensors, or thermistors.
