Thermocouple Temperature Transmitters

Conax Technologies offers a wide variety of temperature transmitters to meet your precise application needs. Transmitters provide an economical alternative to running long lengths of multi-conductor shielded cables for RTDs or specially compensated, shielded extension-grade wire for thermocouples. The output is less subject to distortion/interference from external electrical noise... (read more)

Thermocouple Wire

Conax Technologies’ Con-O-Clad® Mineral Insulated Metal Sheathed Thermocouple Cable is manufactured using high performance/exotic alloys for critical applications where performance under extreme temperatures or severe environmental conditions is required. We can custom design Con-O-Clad to your specifications. (read more)


Thermowells are pressure-tight receptacles that extend the life of a temperature sensor in environments where the sensor is not chemically compatible with the process media or the sensor does not have the mechanical strength to withstand the process flow or pressure. Thermowells also facilitate removing, changing, checking, or replacing sensors without draining the process system. (read more)
