Temperatures up to 2000°C and above
Tempsens offers special Ultra high temperature thermocouples for high temperatures upto 2300 °C for highly corrosive and/or reducing atmospheres. These thermocouples are offered in either Pl atinum/Rhodium (t ypes R, S , or B) Tungsten/Rhenium (types C or D) elements, with a variety of insulations and sheath materials. Depending upon the sheath material selected, these thermocouples are used in inert, oxidizing, reducing or vacuum conditions. The maximum temperature is based on the lowest max. temperature of the element, insulation and sheath material. The use of high-temperature sheath materials in an oxidizing atmosphere is possible only to a limited (low) temperature. Excluded from this are sheath materials of platinum alloys. The table on page 4 of this product information serves as an indication. To a large extent these thermocouples are used in Temperatures up to 2000°C and above aeronautics, research laboratories and in industry. Ultra High Temperature Thermocouples Ÿ Custom - tailored designs available for many applications Ÿ Suitable for oxidizing, reducing, Ÿ Neutral atmospheres and vacuum Ÿ Pressure-/vacuum-proof bushings available in many forms Ÿ Transition elements variable within a wide range Ÿ Profile thermocouples available on request Ÿ Calibration at high temperature in Inert or vacuum atmosphereSpecial Advantages :In the case of long thermocouples it can be advantageous for cost reasons to have a transition to a different material – e.g. Inconel or stainless steel. The insertion length of the part exposed to the high temperature can be dimensioned as requested. also compensating cables can be used after the transition sleeve.For special applications it is possible on request to mount several thermocouples into a common protection tube. The position of the measuring points for profile thermocouples can be chosen within a wide range.These thermocouples are supplied with tracable calibration and material certificates, in case required each of the thermocouple can be calibrated in specific inert or vacuum atmosphere.
