Accessories for Factory & Mill

Thermocouple Accessories

Ultra Electronics offers a wide variety of hardware and accessories, including heads and blocks, plugs and jacks, tube adapters and compression fittings. Our hardware is offered for efficiency, convenience and added value.

Heads: Iron, steel, aluminum, explosion proof, mini-aluminum and polymer.





Blocks: Numerous configurations of single and dual ceramic blocks designed to fit various heads.









Connectors: Plugs and jacks (low-temp, ceramic, mini, jab-in, three-pole, dual), Fast-Fix host junction connectors, wafer heads and panel strips.





Ceramic Insulators: Manufactured in a wide range of diameters, bore sizes and configurations, ceramic insulators are available in alumina, mullite and hafnia.





Thermowells are designed to add additional protection to temperature sensors such as thermocouples and RTD assemblies. They isolate the temperature sensor from the application environment, allowing for longer sensor life. Offered in many different materials such as carbon steel, stainless steel, Inconel® and Hastelloy®, thermowells are available in straight bore, tapered bore, weld in and flanged mount.






Metal Protection Tubes: We have a large inventory of raw materials on hand at all times, allowing us to respond quickly and efficiently to your needs. Where corrosion resistance or high temperature resistance is a concern, Ultra Electronics offers protection tubes in various stainless steel grades: 304, 316, 446 and Inconel 600 & 601, in a variety of wall thicknesses. We also manufacture carbon steel and cast iron protection tubes for applications where corrosion resistance is not as critical, but additional protection of the thermocouple is still desired.  We also offer angle assemblies, flanged assemblies and assemblies with a multitude of bushings, nipples or other fittings welded or cemented.





Ceramic Protection tubes are offered in Alumina, Mullite, Silicon Carbide (with & without collar), Molybdenum. Tubes are available in both open and closed ends, adding further protection to your thermocouple assemblies. Tubes are available in a wide range of diameters, bore sizes and lengths to meet your demands.





Insulated thermocouple grade wire, available in standard limits of error, special limits of error tolerances. Our common thermocouple wire gauges include, 8, 14, 16, 20, 24 and 30 AWG, and custom sizes are available upon request. Insulation types include fiberglass, high temperature fiberglass, PVC, Teflon, vitreous silica and ceramic fiber. Calibrations include Type J, K, N, E and T.

Insulated wire Extension Grade is available. We stock a wide variety of wire sizes, insulation types. Calibrations include Types J, K, N, E and T, and common wire gauges include 16, 20, 24 and 30, among others. Wire is also available with protective overbraid for harsh environments, as required.






Bare thermocouple wire is available in a wide variety of calibration types and gauges. Spools are calibrated to industry specifications such as AMS 2750E, CQI-9 and BAC 5621K. We can also calibrate to your specific requirements.
