Frequently Asked Questions

Q: What is a PT100 thermocouple temperature sensor and how does it work?

A: A PT100 is a type of Resistance Temperature Detector (RTD) made from platinum. It works by measuring the change in electrical resistance of the platinum element as temperature changes — at 0°C its resistance is 100 ohms, increasing predictably as temperature rises. This makes it highly accurate and stable compared to standard thermocouples, and ideal for precision industrial temperature monitoring between -200°C and 600°C.

Q: What probe and cable length should I choose?

A: The right probe length depends on how deep it needs to be inserted into your medium (pipe, tank, or machinery). Common choices are 50mm for shallow installations and 150–200mm for deeper immersion applications. For cable length, select based on the distance between your sensor installation point and your temperature controller or data logger — options range from 1m to 5m to suit most setups.

Q: Is this sensor compatible with standard temperature controllers and PLCs?

A: Yes. The PT100 RTD is one of the most universally supported sensor types in industrial temperature controllers, PLCs, and data loggers. Simply ensure your controller has a PT100 (3-wire or 2-wire RTD) input channel. The M8 × 1.25 screw thread also makes it easy to mount into standard industrial fittings without additional adapters.

Q: Can this sensor be used outdoors or in wet environments?

A: The stainless steel probe provides good resistance to moisture and corrosion, making it suitable for many industrial and semi-outdoor environments. However, for fully submersed or high-pressure liquid applications, verify that your specific installation meets the sealing requirements of your system. The fiberglass-insulated cable is rated for high-temperature environments.
