Thermocouples with
Protecting Tubes
Specification
Description
Straight Assemblies
These thermocouple assemblies include
an element which consists of thermo-
couple wires, double bore ceramic in-
sulators, terminal block, protecting tube
and terminal head. Constructed of high
quality materials to meet the high
Honeywell standards, these ther-
mocouples provide the solution to
temperature sensing problems in ap-
plications worldwide.
Mounting Attachments
Metal Tube
Terminal heads are available in two
types: screw cover (weatherproof)
shown in Figure 1 and general purpose.
Both types have 1/2-inch conduit con-
nection and the screw cover head is
also available with 3/4-inch connection.
Mounting bushings and adjustable
flanges are also available.
