PT100 Sensor 3 Wire, 5mm Dia 50-200mm Length Stainless Probe 400C Max (2M Lead)

Prewired PT100 Sensor, 3 Wire Type Our PT100 sensors are suitable for general industrial use. Fitting is possible into solid bodies (drilled hole) or free air. They offer reliable and accurate measurement. Installation is simple to achieve, using the M8 threaded end portion to secure the sensor in place. Connections are prewired to U-shaped crimps which can be reterminated as required. This is a universal product, compatible with any 2 or 3 wire PT100 input — including our own range of PID Temperature Controllers and Electronic Thermostats, as well as third-party PLCs, dataloggers, and general measurement tools. Select the appropriate probe length from the drop-down box. Type: PT100 (positive coefficient resistance type) Operating Temperature: -50~400℃ Probe Diameter: 5mm round probe Probe Length: 50mm, 100mm, 200mm measuring portion Cable Internal Insulation: Fibreglass Features: M8 outer thread, protective spring Length: 2M overall inc. braided cables 3 Wire PT100 Datasheet Download PT100 Sensor FAQs Q. Can this sensor be used to replace a 2 wire version?A. Yes, simply do not connect the calibration wire. Q. What is the purpose of the 3rd wire in a 3 wire PT100 sensor?A. Long cable lengths will add to the overall resistance and can give an inaccurate reading. The 3rd wire is used to measure the resistance of the leads. This allows for compensation in the final calculation, i.e. greater accuracy. Q. How can you identify the calibration wire?A. With a multimeter you will find continuity between two of the cable cores. Either one can be used for calibration. Q. When are PT100 sensors preferred to thermocouples?A. PT100 sensors are better for general industrial measurements up to around 500°C, because they offer greater accuracy, long term stability, and noise immunity. Q. Can PT100 sensor cables be extended?A. Using the three wire type PT100, it's possible to extend above 100M. For very long distances over 200M, we recommend one of our temperature transmitters to convert the signal to 4-20mA. Q. Which controllers is this compatible with?A. Any device with a 2 or 3 wire PT100 input — popular pairings include the Novus N1030-PR PID controller and the Novus N322 PT100 thermostat, or browse our full PID Temperature Controllers and Electronic Thermostats ranges. Industry Applications General Industrial Temperature Measurement — accurate readings up to 400°C in solid-body or free-air mounting. PID Controller & Thermostat Retrofits — universal PT100 input compatibility across our controller and thermostat ranges. Long Cable Runs — 3-wire design compensates for lead resistance over extended distances.
