Plastics Industry Sensors 

Durex manufactures a complete line of thermocouples that are specifically designed for use in the plastics processing industry.

These thermocouples are typically ANSI type J or type K calibration and consist of a flexible thermocouple conductor that is insulated with fiberglass. Designs utilize industry standard bayonet fittings or threaded fittings that retrofit most plastics processing equipment that is currently on the market.

In addition, Durex offers many European or Japanese retrofit parts with equivalent color codes for direct replacement in these machines.

Typical terminations are split leads, spade lugs, or polarized male plugs. Other terminations are available for application specific requirements.
