Part Numbering System

Richards Thermocouple elements are available in many configurations. Some of the more common types and forms are shown in the tables below.  If you need a special type, phone one of our sales engineers. We can make them to your specifications. The part numbers below describe the thermocouple element type, wire gauge, method of insulation, and construction.

       Example: The part number 8K2-36 signifies an 8 gauge (3.3 mm), Type K, oval ceramic insulated and 36 inches long (914.4 mm) element. Also see Configuration 2 for a representation for that particular thermocouple element.
