Hermetically Sealed Wire Thermocouple & RTD Sensors

Featured Product News

An IP67 wire sensor that is hermetically sealed for use in corrosive or wet environments.

This versatile multi-purpose sensor has been specifically designed for use in and to protect against corrosion in harsh or wet environments. It has a quick response time and can be easily cleaned. The impermeable PFA insulated flexible wire thermocouple provides exceptional resistance to oils, fluids, gases, and chemicals and is electrically isolated.

The tip contains the sensing connection, which is weld-sealed to give a continuous PFA coating along the entire length and provide an atmosphere that is airtight and moisture-proof.

Available in IEC, ANSI and PRT calibrations, in 1,2 or 5m lengths, with bare tails or thermocouple plug termination.

Technical Resources

We offer comprehensive reference guides for users of thermocouples, PRTs and thermistors and associated instrumentation.

Detailed enough for engineers and scientists, it is also suitable for technicians and students. Written with practical bias, the guides contain considerable reference data and basic theory and is therefore of great value as a training aid for those entering the field of temperature measurement and control.

The broad scope of the guides includes detailed temperature sensor guidance, sensor theory and practice and comprehensive applications guidance. The guides describe temperature control, transmitters, instrumentation and data acquisition and a reference section carries that has a wealth of data on thermocouple and platinum resistance thermometry.

The emphasis is on practical aspects, but the basic theory and applications aspects will be of particular interest to students and apprentices.
