Sheathing thermocouple
Sheath thermocouples have been used very successfully for many years in the field of contact temperature measurement. They offer advantages due to the large temperature range from -200° to +1200°C and in the easy and flexible handling with mechanical insensitivity. The thermocouples have very short response times, are easily bendable and vibration-resistant, as the thermocouple wires are embedded in a compact insulation of MgO.
They have an outer sheath of stainless steel or Inconel. This material is easy to weld, has excellent strength properties even at higher temperatures and can withstand most environmental conditions. The most common thermocouples are type K according to IEC 584-3. Almost all type classes such as T and J or N and S are available from Electronic Sensor.
Different diameters, lengths and types (e.g..: J, N, S, L, B, T, E) on request.
