General Industrial Type Assemblies

Industrial Type Base Metal Thermocouple Assemblies are designed to be used in the most severe and demanding environments.  the choice of a specific style is to a large degree determined by the temperature working range, ambient atmospheric or media conditions, as well as the size and shape required for the application.  control requirements such as accuracy and speed of response may also be considerations.

When speed of response is critical, specify the open end construction.  An exposed element is directly subject to corrosion and physical damage; therefore, this style should be used only after consideration of the relative need for the fast response versus thermocouple life.

Another feature for improving response time is the Butt-welded junction.  This design has less mass and therefore faster response time than the Twist-weld which is normally supplied by Barber-Coalman.  The Twist-weld offers greater mechanical strength and longer life.

CAUTION REGARDING OPEN END PROTECTION TUBES
For applications requiring a higher speed of response, specify the open end construction.  Open End tubes should be specified only after consideration of the relative need for fast response versus thermocouple life.  The exposed thermocouple element's life is limited by a surrounding media that is corrosive at high temperatures, and that will allow exposure to physical damage.

Butt Welded Thermocouples
The two common methods of making junction construction are butt-welding and twist-welding.  The twist weld is normally supplied by Barber-Coalmen because of its greater mechanical strength and longer life.  Butt-welded construction has less mass and therefore faster response time when used unprotected.  A protection tube slows response time.
