RTD Assemblies

III RTD Assemblies

Conax Technologies’ wirewound platinum RTD assemblies feature a wirewound element encased in either a stainless steel or Inconel 600 sheath. The RTD’s nickel leadwires are supported and insulated throughout the sheath with densely compacted high-purity magnesium oxide. This allows the sensor to be bent like a thermocouple except in the tip portion that contains the element.

Thermocouple Assemblies

III Thermocouple Assemblies

Conax thermocouple assemblies represent the culmination of 60 years experience in the design and manufacture of temperature sensors. Conax thermocouple have proven their durability and reliability in applications ranging from large industrial processing plants to highly specialized laboratory testing and validation.

Application-Specific Temperature Sensors

III Conax Power Generation Temperature Sensors
High Performance Fittings

Conax offers a wide range of OEM parts for various power generation applications. All temperature sensors are designed, machined and assembled in the USA using the finest materials and workmanship available. Sensors can also be manufactured and improved for any turbine manufacturer for HP or LP sections and bearing monitoring.

III Conax Furnace & Autoclave Temperature Sensors

For more than 50 years, Conax Technologies has served as a leading source of temperature sensor and pressure/vacuum sealed fittings feedthroughs for the Furnace and Autoclave Industry.

III Conax Semiconductor Temperature Sensors
Conax Semiconductor Fittings

Conax Technologies manufacturers a wide variety of temperature sensors including thermocouples, RTDs and thermistors. For the semiconductor industry, the most popular type of sensors we manufacture is thermocouples which are typically used in high temperature (up to 1200oC) and highly corrosive (ex. Hydrochloric acid) environments.

Mineral Insulated Cable

III Mineral Insulated Cable
Conax Furnace & Autoclave Fittings

Conax Technologies manufactures our exclusive mineral insulated (MgO) Con-O-Clad® bulk material for single and multiple pair wires. This is available in all ASTM base metal thermocouple calibrations in sizes from 0.040″ to 0.375″ diameters. Other non-standard material combinations may be furnished for special requirements.

Mounting Methods

Termination Styles

III Conax Termination Styles
High Performance Fittings

Conax offers an assortment of termination styles and terminal heads for multiple environment and application uses.


III Conax Thermowells
High Performance Fittings

Thermowells are pressure-tight receptacles that extend the life of a temperature 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. The use of standardized thermowells throughout a plant permits easy relocation of sensors.
