SUP-WRNK thermocouples sensors is mineral insulated construction which results in thermocouples wires that are surrounded by a compacted mineral insulation (MgO) and contained in a sheath such as stainless steel or heat resisting steel. On the basis of this mineral insulated construction, a wide variety of otherwise difficult applications are possible.
Sensor: B, E, J, K, N, R, S, T
Temp.: -200℃ to +1850℃
Output: 4-20mA / Thermocouple (TC)
- Wide application in measurement
Small diameter thermocouple is very usefull for the place where space is at premium. Mineral insulated construction is resistant to high pressure and also used at wide range of temperature from-200°C to +1260°C.
- Quick response
Mineral insulated thermocouples have small heat capacity due to the small sheath size, the small thermal mass is highly sensitive to change in temperature and gives a very fast response.
- Easily bent for installation
The ability to form mineral insulated thermocouples on a radius twice the sheath diameter makes for simple and on-the-spot installation into complex configurations.
- Long Iife span
Contrary to conventional thermocouples which suffer from deterioration of electromotive force or wire disconnection, etc., mineral insulated thermocouples wires are insulated with chemically stable magnesium oxide, thus assuring a longer service life.
- Excellent mechanical strength and pressure Resistance
The composite construction is resistant to extreamely high vibration levels, and by choosing appropriate sheath material, it is reliable to use in corrosive atmospheres and abnormally high or low temperatures. Though it has small diameter, it can withstand about 350 MPa at a temperature of 650°C.
- Custom sheath outer diameter available
Sheath outer diameter sizes between 0.25mm and 12.7mm can be provided.
- Custom long length
Length are available up to a maximum of 400m. Maximum length is dependent upon the sheath outer diameter.
