TC with protective armatures
Against chemically and mechanically harsh environments thermocouples are mounted inside protective armatures. The optimum design depends on the individual application.
The alternatives are straight thermocouples, angular thermocouples (preferred for salt baths, metal melting plants, etc.) and thermocouples with exchangeable measuring inserts.
The protection tubes are made of ceramic or metallic highly temperature-resistant materials. The thermocouples are available in different mounting techniques, e.g. screw-in, weld-in or plug-in, with connection flange, or other.

Mineral Insulated Thermocouples are manufactured from mineral oxide insulated metal sheathed cable. Mineral Insulated Cable consists of thermocouple wire insulated by compacted magnesium oxide surrounded by a metal sheath. TCP's Thermo-Pak M. I. Cable is manufactured to exacting standards from the highest quality materials available to ensure accurate and reliable performance with long life. Mineral insulated thermocouples are more durable, faster responding, longer lasting and capable for use at higher temperatures than ceramic insulator or fiberglass insulated thermocouples because the wires are encased and protected by compacted insulation and the metal sheath. Maximum operating temperatures of thermo-pak manufactured thermocouples are determined by the wire calibration type and the sheath alloy selected.

Thermistors tend to be more accurate than RTD's and thermocouples, but they have a much more limited temperature range because of their marked non-linearity.
A Thermistor capitalizes on the fact that the electrical resistance of a material changes as its temperature changes. Thermistors rely on the resistance change in a ceramic semiconductor, with the resistance dropping non-linearly with a temperature rise.
Thermistors can be a low cost solution to temperature measurement. They tend to have large signal outputs and their small size permits fast response to temperature changes. UE Thermistors are used to measure temperatures from -45° to 260° C (-50° to 500° F)

Thermocouples can measure temperatures over wide ranges, inexpensively. They are very rugged, but they are not as accurate as RTDs and thermistors.
A thermocouple is basically two strips of wires of dissimilar metals. These metal wires are joined at one end and the voltage is measured at the other end. Changes in the temperature at the juncture induce a change in electromotive force (emf) at the other end. As the temperature goes up, this output emf of the thermocouple rises, though not necessarily linearly.

Mineral insulated thermocouples are widely used for temperature measurement in many applications. To their essential characteristics -sensing element, insulation, protecting sheath material and connection- those thermocouples add unique properties such as bending possibilities (to suit any environment) and a wide range of dimensions (from miniaturization to great lengths). The bare ends termination offers flexible and direct connection possibilities.
