Thermocouple Assemblies
with Flexible Fiberglass Insulated Leads
A8B Series
These thermocouples are available with either stainless steel or inconel sheaths. Fitted with a transition from the sheath to 36 inches of fiberglass insulated (insulation code 828) flexible leads. Available in thermocouple types E, J, K, and T as a standard assembly. Other thermocouple calibrations as well as various lead wire insulation materials are available upon request.
Maximum service temperature of the transition adaptor is 400 degrees Fahrenheit. Maximum use temperature of the thermocouple is determined by considering the sheath material being used and the thermocouple calibration. Standard units are 12 inches long, units can be made as short as 1-1/2 inches long without any special consideration.
- When ordering, specify Part No. and Length “L” Example: A8B-1-12
- PFA Teflon® encapsulation - good to 450°F, can be added to any probe.
- Duplex and multiple units also available.
NOTES:
- For high temperature (800 degrees Fahrenheit) connectors and miniature plugs and jacks see our F2 and F3 Series.
- All assemblies use magnesia (Mg0) internal insulation. Contact factory if other types of insulation are required.
Thermocouple calibration type N is available in all sizes.
