Mineral insulated resistance thermometers without an extra protection tube (52-WOS) are used for general temperature measurement up to 600°C, on rare occasions up to 800°C. They are suited for surface temperature measurement as well as measurements of liquids and gases
This series has no extra protection tube and are often used when a fast response time of the sensor is desired. Diameters from 2 mm up to 10 mm are mineral insulated possible. These mineral insulated thermometers allow the use of a compression fitting.
Depending on the connection type (2-wire, 3-wire or 4-wire – in turn depending on the required measurement precision and connector length), resistance thermometers consist of 2, 4 or 6 copper feed lines (inner conductors), surrounded by a thin metallic protective mantle, usually made of high-grade steel.
The inner conductors are firmly press-fitted and insulated in ceramic powder. The precision resistor inside the sensor tip is connected through the inner conductors.
As a result of their structure, mineral insulated resistance thermometers have the following advantages:
