Sheath resistance thermometer without 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
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:
- Small physical dimensions with maximum flexibility for temperature measurement at sites with difficult accessibility (diameter 1,5 – 6,0 mm)
- Short response time for exact measurements of temperature variations
- Optimal protection for the sensor system against corrosion, oxidation, phyiscal damage and chemical contamination as a result of the enclosed structure
- The enclosed structure also facilitates application of these sensors without additional protective fitting
