Thermocouples Straight - Metal
Single Metal Protection Tube | 90° Bend | SH Head
Straight thermocouples utilize metal protection tubes. They are used to monitor temperatures for heat treating, salt baths, casting, or hot dip galvanizing. These thermocouples have a single metal protection tube. A variety of high temperature alloys can be used for the tube. Sturdy construction keeps the thermocouple from loading damage. Threaded bushings can be welded to the protection tubes.
Construction
Example: The part number describes the thermocouple giving the gauge, type of wire, construction, tube length and mounting device, if any. The part number 8K4-1012XH-24-AF signifies an 8 gauge, Type K complete assembly, 1/2” NPT extra heavy 24” long #10 alloy (32% nickel - 215 chromium) tube, a 1/2” Adjustable Flange and a screw cover head. Other combinations of thermocouples and tubes can be specified depending on your application.
! Note: If you would like to order a Type E, J, or N assembly, just substitute the “J” with an E, J, or N in the part numbers listed on this page.
Straight Thermocouple Configurations
Part Numbering System Examples
To change the standard type K thermocouple calibration. Substitute the K in the part number with the desired Type E, J, K, N, or T, calibration.
Example: 8K4-734XH-12 = Type K Thermocouple
Example: 8J4-1612XH-12 = Type J Thermocouple
