Products - MgO Type Thermocouples          Return to Product Index

MgO type thermocouples have a compacted ceramic powder insulation with
an outer metal sheath.



Temperature vs. Diameter and Material Table. Temperature limits are higher than those of Miniature or Probe styles. Any flexing should be in an arc of a reasonable radius - to tight an arc may cause failures in the thermocouple element. Generally more expensive than Miniature of Probe styles. Jab-style Jacks are standard.

Grounded junctions (G) are standard, but for Ungrounded (U) or Exposed Junctions (E) change the "G" to "U" or "E" in the part number.

For Dual elements insert "D" after "4" in part number. Example: 18K4DS9

Thermocouple Types E, J, K, T - Plug only
Thermocouples normally have the Plug on the thermocouple and the Jack on the Extension Wire, however,
they may be made either way.

Grounded junctions (G) are standard.

Thermocouple Types E, J, K, T - Plug and Jack 
Jab Style plug is standard where "3" is indicated in the part number.
Example: K3 = K1 + K5 (see Plug and Jack section for pictures and descriptions).

Thermocouples normally have the Plug on the thermocouple and the Jack on the Extension Wire, however,
they may be made either way. Grounded junctions (G) are standard.

Thermocouple Types E, J, K, T - Transition Fitting (TR)

Provides a Transition Fitting  to protect the joining of the extension wire to the swaged thermocouple.
Usually smaller gauge thermocouple wires are joined to larger gauge extension wires. Connection is
not as mechanically strong as use of plugs and jacks or weatherproof heads. For other diameters
consult factory. Grounded junctions (G) are standard, coiled relief spring is optional. 

Insert length of metal sheath (Y) and total length (X). 3 inch leads are standard.

Thermocouple Types E, J, K, T - Transition Fitting (TR) and Flexible Extension (FE)

Provides a Transition Fitting  to protect the joining of the extension wire to the swaged thermocouple.
Usually smaller gauge thermocouple wires are joined to larger gauge extension wires. Connection is
not as mechanically strong as use of plugs and jacks or weatherproof heads. For other diameters
consult factory. Grounded junctions (G) are standard, coiled relief spring is optional. 

Insert length of metal sheath (Y), Total length (X), and Flexible Extension length (Z). 3 inch leads are standard.
