Mineral insulated metal sheathed thermocouples

Mineral-Insulated Metal-Sheathed (MIMS) thermocouples were successfully introduced many years ago into temperature measurement technology.

The standard versions are mainly used in the range between -270 °C and +1200 °C. They combine the advantages of high flexibility and easy handling in an extremely wide temperature range. They are supplemented by high-temperature MIMS thermocouples for operating temperatures of 2000 °C and above.

Inconel 600 is mainly used as sheath material, a nickel-based alloy. This material can easily be welded and soldered, it possesses extremely good resistivity characteristics also at higher temperatures and is resistant against most ambient conditions.

The thermocouple is often the type K (NiCr-Ni) acc. to IEC 60 584-1. Widely in use are also types L resp. J (both Fe-CuNi) and in the higher temperature range the noble metal types S R and B, which are platinum/rhodium alloys. The thermocouple wires are embedded in a compact insulation of high-purity MgO and enclosed by a metal sheath of a nickel/chromium/iron alloy or of stainless steel. The compact insulation fixes the wires securely so that no damage can occur because of strong vibrations or high bending loads. Also short circuits between the wires or between wire and sheath are virtually impossible.

Type AL - MIMS TC with cable

Type AL - MIMS TC with cable

In the design AL the connection cable is hard-wired. The transition sleeve has a diameter of 6 or 8mm, depending on the type of cable. The standard length is 50 mm. The cable type (conductor cross section, insulation structure, screening) can be choose from a wide range.

Standard is a screened cable with individually Teflon-insulated wires and jointly PVC-insulated, with a cross section of 0.25 mm. Max. temperature at the sleeve = 85 °C.
