Bayonet Adaptors

Pipe Clamp Adaptors for Bayonet Type Thermocouples | Extension Cable Assemblies
Spring-Loaded Bayonet Cap Type Thermocouples are used in conjunction with bayonet adaptors. After inserting the thermocouple sheath through the adaptor the spring is compressed and locked by the cap pushing the sensing junction tight against the surface being measured for increased accuracy and faster response time.

Pipe Clamp Adaptors for Bayonet Type Thermocouples

Spring loaded bayonet cap type thermocouples are used in conjunction with bayonet adaptors. After inserting the thermocouple sheath through the adaptor the spring is compressed and locked by the cap pushing the sensing junction tight against the surface being measured for increased accuracy and faster response time.
Pipe Clamp adaptors permit thermocouple placement without the drilling and tapping of holes to attach the adaptor.
