Description

 ET231 Series surface thermometers with bayonet lock are intended for measuring temperatures in solids, on bearings and moulding tools, for example in the plastics industry.

Thanks to the conical shape of the measuring tip, these temperature probes are suitable for use in  cone-shaped bores.

The rugged pressure spring acts as a cable protector and ensures a uniform pressure between the measuring tip and the bottom of the hole. The sensor provides good heat transfer through adjustable spring pressure. The fitting length can be altered by rotating the bayonet lock. 

The sensor is normally a Pt100 temperature sensor to EN 60 751, Class A in 3-wire circuit. Versions with  thermocouples, Pt1000, PTC or NTC sensors are available on request.
