Waterproof PT100 Sensor With 3 Wire Braided Lead
This durable sensor is waterproof and resistant to oils. It can be used to measure temperatures between -200 and 450 degrees Celsius. Suitable for insertion into materials such as metals. The compact sensing probe makes this a great solution for areas with limited mechanical access.
The sensor wiring is protected by a high quality sheath. The cable cores are terminated to U shaped crimps with around 80mm of cable exposed — ready for connection to temperature controllers, temperature transmitters, or dataloggers. This sensor can also be used with PLCs which have a suitable analogue input.
Includes calibration wire for compensation of overall cable length. Suitable for replacement of existing 2 and 3 wire PT100 sensors, including our own range of PID Temperature Controllers and Electronic Thermostats.

Frequently Asked Questions
Q. Is this suitable for wash-down or outdoor environments?
A. Yes — the sensor and cable sheath are waterproof and oil-resistant, suitable for damp, wash-down, or exposed installation locations.
Q. Can this replace a 2-wire PT100 sensor?
A. Yes — simply don't connect the calibration wire, and it functions as a standard 2-wire sensor.
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.
