Conax Technologies

Techni Measure offers feedthroughs, thermocouples and RTD sensors by Conax Technologies. Thermocouples and RTDs are both used for temperature measurement, but they differ in how they work, their temperature ranges, accuracy, response time, and cost. RTDS measure temperature by detecting changes in the resistance of a metal, while thermocouples measure temperature by generating a voltage proportional to a temperature difference between two dissimilar metal junctions.

Feedthroughs

Conax Technologies’ range of compression sealing glands and feedthroughs are designed to reliably seal probes or power/instrumentation wires that pass through a pressure or environmental boundary. A choice of seal and body materials are available to cover a wide range of pressure, temperature and medium types.

Thermocouples

Thermocouple operation is based on the fact that when wires of two different materials are joined together at one end and placed in a temperature gradient, a thermoelectric voltage is observed. Various materials are used to obtain the best output for any given temperature range, and these are described by the ISA letters T, J, E, K, etc. Various sensor elements, sheath materials, probe constructions and mounting styles are available.

RTD’S

TD’s are based on electrical resistance changes through a material that changes in proportion to temperature. The resistance increases with increasing temperature and the most common material is Platinum. Various sheath materials, probe constructions, and lead wire output options are available.
