C-Temp International offers mineral-insulated, plastics industry, and cut-to-length thermocouples. Mineral-insulated parts are manufactured from 0.010" to 0.5" diameter, with a variety of sheath materials such as 304SS, 310SS, 316SS, Hastelloy X, Iconel 600, Iconel 601, Iconel 702, molybdenum, and tantalum.

Watlow carries an array of thermocouples. General application styles include adjustable spring type thermocouples that fit a large range of hole depths and bend to any angle, and armor style thermocouples with stainless steel hoses that offer additional lead protection in demanding applications. Mineral-insulated thermocouples come in the basic cut and stripped style, wafer head Style AS, and thermowell-compatible Style AT.

Convectronics designs an array of thermocouple types to meet almost any application need. Bare wire thermocouples are available in 6 standard configurations. Fixed and adjustable bayonet thermocouples are offered in standard J, K, T, and E base metals. Other types include nozzle, bolt style, metal sheath/MI, paddle, lug and washer, bearing, ribbon, sabre, refractory metal/ceramic, and noble metal thermocouples.

Thermal Devices offers multiple thermocouple designs for various industries. Plastics industry thermocouples come in a variety of braided or armored leads, from 48" to 96", while variable depth, armor-style thermocouples come in type J standard, lengths from 48" to 144", and stainless steel armor leads standard. Surface mount thermocouples are offered in type J and ring lug style, as well as in 72" and 120" sizes. Another type is the MgO thermocouple for temperatures to 2,200 degrees Fahrenheit, and for even hotter temperatures, an ultra-high temperature thermocouple made from platinum.

Three main types of thermocouples are offered by National Plastic Heater Sensor & Control. Plastics industry products include adjustable depth bayonet thermocouples, fixed bayonet thermocouples that are straight or bent 45 or 90 degrees, and compression fitting thermocouples that are straight or bent 45 or 90 degrees. Next, melt bolt thermocouples feature an assortment of options, from standard plug or standard jack, to Flex Armor and Bx connector. Finally, industrial process thermocouples come mineral-insulated standard, with choice of 1" stripped end, plug, process head,or open terminal disk, as well as straight, 45-degree, or 90-degree probe with insulated leadwire.

Heat and Sensor Technology provides a variety of MgO insulated thermocouples, including leadwire, standard connector, miniature connector, snap-cover connection head, and screw-cover connection head styles. They also make plastics and packaging industry thermocouples such as the spring adjustable depth, flex-armour adjustable depth, fixed bayonet, rigid tube, spade, washer/lug, melt bolt (fiberglass or MgO), and pipe clamp styles. Lastly, industrial thermocouples include oil seal and sanitary models. Each of the three categories can be manufactured standard or custom.

Pyromation thermocouples are made for a wide range of applications, be they industrial, general purpose, or hazardous. For example, the FD08 penetration-style thermocouple is used to monitor the internal temperatures of meat, fish, poultry, dough, and other foods; made from full hard drawn 304SS, the materials are FDA compliant for use in sanitary applications.  Another option, the industrial ID01 straight base metal thermocouple, is provided in many styles, from bare to duplex-insulated element, to insulated junction, twist weld, or tig weld. Within the full line of Pyromation thermocouples, temperature measurement is possible between -200 and +2,316 degrees Celsius.

M & M Control features Pyromation thermocouples and components for use in high temperature, heavy industrial processes including heat treating, forging, smelting, melting, utility and waste boilers, incineration, and cogeneration.  Leads are generally made from fiberglass, and sheaths are normally 304 stainless steel. Most assemblies are temperature rated up to 900 degrees Fahrenheit.
