Areas of Expertise

For over 60 years, Conax Technologies has served as a leading source of temperature sensors, compression seal feedthroughs for power, and thermocouple wire feedthroughs for temperature and instrument leads in the Furnace and Autoclave industry. We are the industry leader in the design and fabrication of temperature measurement devices. We offer: • Standard Thermocouple Assemblies for operating temperatures up to 2300° F (1260° C) • High Temperature Thermocouple Assemblies for operating temperatures up to 4200° F (2315° C) • Resistance Temperature Detectors (RTDs) for operating temperatures up to 1472° F (800° C) Conax is the originator of soft sealant technology that, when combined with mechanical compression, results in a remarkably secure seal on wires, probes, and electrodes passing through a pressure or environmental boundary. We offer single electrode and power lead style feedthroughs to cover virtually any need. Our high-pressure and high-temperature power and instrument feedthroughs are engineered for process control in glass lamination, composite bonding, material testing, sterilization, vacuum processing, vulcanizing, curing and more. Conax also offers instrumentation feedthroughs that are available with or without factory installed lead wire. All are available with vacuum and ANSI type mounting flanges in virtually any style you need.

Conax has developed stainless steel sanitary flanged temperature sensors and compression seal fittings that are ideally suited to sanitary applications within the food and beverage industry. Industry leaders have relied on our sliding contact thermocouples for years to ensure hermetic heat sealing in packaging operations.

Conax designs and manufactures accurate, reliable temperature sensors that are used for: • Fusion draw processes that are used in creating chemically strengthened glass, such as Corning® Gorilla® Glass • Float-glass production • Glass melter operation • Forehearth temperature measurement and control

Conax is your single source for solving the world’s energy storage problems. Our high performance electrical feedthroughs make green energy storage an economic reality.

Temperature sensors for cryogenic applications and compression seal fittings feature our soft sealant technology for process control. We have also originated custom-designed solutions for some of our clients’ toughest challenges, including: • A sensor assembly capable of immersion in a cryogenic fluid and withstanding liquid motion forces inside storage tanks • Heavy-duty cast iron pipe clamp thermocouple for liquid nitrogen tanks that stands up to field abuse • A customized compression seal fitting that allows customers to measure liquid nitrogen at cryogenic temperatures in the range of -400°F (-240°C) with the highest accuracy possible in limited physical space

Conax is the originator of soft sealant technology that, when combined with mechanical compression, results in a remarkably secure seal on wires, probes, and electrodes passing through a pressure or environmental boundary. Our compression seal fittings are perfectly suited to devices used in level control and gas detection, providing a secure, reliable seal for wires entering pressure boundaries and connecting sensors and instrumentation devices.

Conax designs and manufactures the industry’s most comprehensive temperature sensors and compression seal fittings for a broad variety of applications. We provide solutions that span the upstream, midstream and downstream sectors of the oil and gas industry, including:

Conax is a leading source for Thermocouple and RTD temperature sensors, compression seal fittings, instrument feedthroughs, retractable analyzer sample probes, retractable chemical injection quills and Class 1, Division 1 wire conduit seals. We have developed customized solutions for a number of highly specialized client challenges, including: • Ultra-high pressure compression seal fittings with 65,000 PSI operating pressure rating • Redundant seal assemblies for probes and instruments inserted into gas or liquid processes • A temperature sensor assembly with an SASIC (Hexoloy) protection tube that can withstand extreme high temperatures and can be rotated 180° to double the life of the sensor • Single and multiple bore split internal compression seal fittings to seal long, down-hole temperature sensors; split internal design allows for the surface assembly at the well-head flange of the seal to fit over the installed sensor’s termination

Conax is the U.S. distributor for Sterisensor™ and Sterimaster™ load probes that are used for FDA required processes and temperature control. The environmental conditions found in pharmaceutical autoclave chambers are extreme for any equipment. These conditions are a major cause of sensor failure in chamber/load probes due to the ingress of moisture into the sensor and the unacceptable leakage of steam/condensate through the bulkhead connection. Designed to withstand these extreme environmental conditions, the Sterisensor’s engineered moisture seal prevents the ingress of moisture, which is the leading cause of failure. Similarly, the Sterimaster Chamber/Load Sensor has been specially engineered to withstand these conditions and offers a reliability factor surpassing anything previously obtainable. Every weld undergoes NDT examination and each completed assembly is leak tested.

Conax has a history of supplying both temperature sensors and vacuum seal fittings and feedthroughs used in the production of solar cells.  Typical products and applications include:

• Redundant thermocouple sensor probes with dual-seal capability to prevent a vacuum leak into the ingot furnacing chamber for polycrystalline wafer production
• Customized sensor/flange assemblies to facilitate quick replacement of sensors during maintenance cycles
• Process control thermocouples utilized inside the deposition chamber for thin-film solar panel production
• Thermocouple wire feedthroughs to pass temperature sensor reading from within the vacuum chamber to external instrumentation
• Electrode feedthroughs to bring power into the vacuum chamber to power heating elements

Conax provides temperature sensors and compression seal fittings and feedthroughs for bearings and bearing housings. Our designs are engineered to help ensure early failure detection and prevent unplanned downtime to reduce your maintenance costs and enhance safety. Using the soft seal technology pioneered by Conax, we’ve engineered our fittings to seal securely on the individual insulated leads of bearing temperature sensors. We have also designed compression seal feedthroughs for cryogenic power applications.

Expanding our focus in the growing Semiconductor industry, Conax now has in-house capabilities to design and manufacture quartz sheaths for temperature sensors. Many of the temperature sensors used inside process chambers need a semiconductor-grade quartz sheath to protect them from the chemicals and temperatures present. Conax identified this as an area in which we can better serve our customers. By producing the sheaths in-house, we maintain greater control over quality and supply; and we can provide our customers with the quality products they need faster.

Conax engineers temperature instrumentation and compression seal fittings that are ideal for laboratory testing and measurement, concept development in academia, and high technology environments.

Conax provides lube oil sensors, stroking piston sensors, bearing temperature sensors and compression seal fittings up to Class I, Division I, explosion-proof applications. All of our temperature sensors and compression seal fittings are specially designed for the specific application.
