Mineral insulated thermocouple
max. 1250 °C | TC MI PS Terwin Instruments Ltd.

The TC MI PS Series of Thermocouples consists of a range of Minerally Insulated
Thermocouples which are terminated directly onto either a plug or a socket that has contacts of
thermocouple material. They are available in a range of sheath materials, a variety of sheath
lengths and diameters.
Having a maximum temperature of 1250°C they are suitable for many applications.
An indication of suitable applications is given below.
316 stainless steel - Excellent corrosion resistance often specified for food and
medical applications.
321 stainless steel - Good corrosion resistance and high ductility. Widely used in
industry.
310 stainless steel - Good corrosion resistance at high temperatures and
recommended for use in sulphurous atmospheres.
600 Inconel alloy - Good resistance to oxidation and extremely corrosive
atmospheres at high temperature. Not recommended for use in sulphurous
atmospheres.
Nicrobell - Recommended for use with type N conductors. Nicrobell is a Ni/Ch/Si
alloy that is suitable for use in reducing, oxidising and vacuum atmospheres.
