Frequently Asked Questions
Q: What is a PT100 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 — PT100 sensors have a resistance of 100 ohms at 0°C. They are known for high accuracy, stability, and a wide measurement range, making them a preferred choice for industrial and scientific temperature monitoring.
Q: What cable length should I choose for my application?
A: This PT100 sensor is available in five cable lengths: 0.5M, 1M, 2M, 3M, 4M, and 5M. Choose a length based on the distance between your measurement point and your temperature controller or data acquisition system. Longer cables (3M–5M) suit larger equipment or installations where the controller is mounted away from the probe. Shorter cables (0.5M–1M) work well for compact setups like 3D printers or small appliances.
Q: Is this PT100 sensor compatible with common temperature controllers?
A: Yes. This 3-wire PT100 RTD sensor is compatible with a wide range of temperature controllers, PLCs, and data acquisition modules that support PT100/PT1000 RTD inputs. Always verify that your controller supports a 3-wire PT100 configuration before connecting.
Q: Is the probe truly waterproof?
A: The probe itself is constructed from stainless steel and is waterproof, making it suitable for liquid immersion and wet or high-humidity environments. However, the cable and connector end should be kept away from direct water exposure unless your installation includes additional sealing.
