Ceramic Sheathed Vacuum Thermocouples
Type 40/41 assemblies incorporate an integral Spectite® seal and are ideal for vacuum furnace applications. The Spectite® vacuum seal is rated to 5 x 10-6 torr with low leak rates (better than or equal to 1 x 10-6 scc/sec. under 1 Atm @ 20ºC). These thermocouples can be supplied to all recognised standards and tolerances when combined with our UKAS calibration services. They are available in simplex and duplex junction styles with an optional test sensor hole for calibration / survey work. A wide range of support tube fittings for attachment into the process is available.
  • Vacuum seal rated 5 x 10-6 torr
  • Low leak rates
  • Integral Spectite® seal on internal wires maintains vacuum even if sheath is damaged
  • Wide operating temperature range up to 1600°C
  • Wide range of attachments for process installation
  • Simplex and Duplex versions available
  • UKAS and In-House calibration options available to all major international and industry specific standards
  • Flexible tagging options available for clear traceability

2 Sheath Material Operational Properties Max.
Temperature
IAP Impervious Aluminous Porcelain Ideally suited for use with base metal thermocouple conductor combinations. Has a very low temperature coefficient of expansion thus giving excellent resistance to thermal shock. Offers high strength and high resistance to flux and slag attack. Suited to kiln applications where low contamination requirements preclude the use of a metal sheath. NB. Requires support at high temperature if horizontal. 1400°C
IRA Impervious Recrystallised Alumina Ideally suited for use with precious metal thermocouples at high temperatures. Provides a fair resistance to thermal shock. High degree of inertness to chemicals. Ideal for reducing carbonaceous atmospheres and offers a high resistance to alkaline and other fluxes. 1600°C

INSULATED
Hot junction insulated from sheath. Gives floating output with typical insulation resistance in excess of 100 megohms

EXPOSED
Fastest response mainly for the measurement of air temperature in ducts. Restricted to a maximum operating temperature of 300ºC
