Thermocouple types and assemblies
Industrial Thermocouples
Available types include Type R, Type K and selectable J/K assemblies, with pipe, sanitary and weatherproof-head models. Check each product's construction and measurement details against the intended measurement point.
Browse products by assembly style in the thermocouple head-type and thermocouple transition-type categories.
Thermocouple MI
MI J/K thermocouple with listed sheath, diameter and grounded or ungrounded junction options for furnace, oven and heat-treatment measurement.
R Type Thermocouple
Pt/Pt-Rh13% high-degree measurement thermocouple.
Catcon Thermocouple
K-type thermocouple listed for supported automotive engine and CNG gas testing contexts.
Pipe Temperature Thermocouple
Contact thermocouple with a curved plate for pipe-surface temperature measurement; Type J/K, grounded/ungrounded junction and SS304/SS316 sheath options are listed.
Tri-Clover Thermocouple
Tri-Clover assembly with selectable J/K types and grounded or ungrounded junctions, listed for supported sanitary and clean-in-place food, dairy, beverage and biopharmaceutical processes.
Weatherproof-Head Thermocouple
Weatherproof-head assembly with selectable J/K types, simplex or duplex construction and SS304/SS316 sheath options.
Choosing a thermocouple
Check the product's element, junction, sheath, mounting, cable route and connection against your measurement point and instrument. Confirm any required range or approval for the complete assembly.
Compare thermocouple assembly styles
Head-type assemblies
Browse connection-head constructions where the head, process connection and insertion dimensions are part of the installation. Check the individual model's junction, sheath and assembly options.
Head-type thermocouples →Lead-wire and connector probes
Compare transition-type probes by cable route and termination. The J-type MI quick-disconnect model has a connector; other constructions use lead cables or handles.
Transition-type thermocouples →Surface and sanitary formats
Pipe and surface probes measure through contact with the outside surface. Tri-Clover assemblies use a different process connection. Choose around the point and mounting, not only the sensor type.
Surface-contact options →Which thermocouple types can I compare?
The range includes Type J, Type K and Type R. Type and construction are separate choices: confirm the complete assembly's operating requirements, dimensions and instrument input.
What should I send for a replacement?
Send the existing part number or drawing, type, junction, sheath diameter, insertion length, connection, cable length and quantity. Include normal and maximum process temperatures and the receiving instrument. Separate the thermocouple type from the assembly style in your enquiry: a J or K element can have different mounting and termination arrangements. Ask for each quoted line to identify both, including any proposed substitution. The manufacturer overview explains manufacturing and quality documentation.
