High Temperature Thermocouple with Die Cast Alloy Angled Terminal Head

High Temperature Metal Sheathed Thermocouples (Type 27)

Send Enquiry Request Info Data Sheet

These high temperature thermocouples are used in applications where other thermocouples would fail due to excessive heat or severe environments. Utilising specialist exotic sheath materials such as Platinum 10% Rhodium, Molybdenum and Tantalum they can be used in service temperatures up to 2300°C. The combination of conductor, insulation material and sheath must be carefully selected to suit your process environment, service temperature and installation requirements (i.e. whether the probe is flexible or not). Our experienced sales team are on hand to assist where needed, so please do not hesitate to contact us if help is required.

Typically used with high temperature thermocouple types R, S, B, C and D
Temperatures up to 2200°C (continuous use) or 2300°C (short term use)
Semi-Rigid (mineral insulated) and Rigid (tube) styles available
Terminated in a die cast alloy angled terminal head with grub screw
Calibration service for oxidizing and inert environments is available up to 1600°C
