While the "Tube Temp" design has attracted many imitations, the Tube Temp's patented "Knife-edge" thermo-junction provides accurate readings unmatched by any competing product.

The "Tube Temp" is the Most Accurate Measurement Device for Fired Heater and Industrial Boiler Tubes on the Market Today

TCP's "Tube Temp" thermocouples are ideal for the reliable measurement of tube wall temperatures in fired heaters which is important for prolonging tube life and ensuring safe and efficient operation. Accurate tube wall temperature measurement allows the operator to adjust operating conditions to limit tube wall temperatures below allowable limits while maximizing product flow.

The "Tube Temp's" construction offers outstanding advantages for the temperature measurement:

No special supports required within the heater fire box because of the inherent high temperature strength of the sheath materials.

Minimum radiant heat blockage "shadow effect" due to a small diameter when compared with pipe and insulator systems.

TCP's "tube Temp" thermocouple is one-half inch (.500") diameter with a sheath wall thickness of nominal .120" (except Hastelloy material). The insulating material is highly compacted magnesium oxide and the conductors are nominal #14 B & S Gauge. A fused junction provides a direct, totally metallic heat transfer path from the tube wall to the sensor. Readings are unaffected by hot combustion gases.

Many standard configurations of the "Tube Temp" are available to fit your application. The following pages outline calibrations, lengths, junction style, sheath material, wrap-around angles, and other information necessary for selecting the appropriate "tube Temp" model. "Tube Temp" thermocouples can be designed and factory formed to suit nearly any custom installation or application.
