Plastics Equipment Industry Temperature Sensors

Plastics Equipment Industry Temperature SensorsTemperature sensing and measurement are critical to all successful plastics processing and molding applications.  Injection molding equipment, hot runners and manifolds, extruders and extruder barrels, and blow molding equipment all use Durex' Resistance Temperature Detector (RTD) and Thermocouple (TC) sensor assemblies.  As the industries preferred supplier of extruder cast barrel heaters, Durex has designed complementary thermocouple and resistance temperature detector sensor solutions.

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 can be retrofitted into 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.

The use of Resistance Temperature Detectors (RTD’s) in the plastics industry is increasing due to their accuracy, stability, and advantages in control circuitry. Durex manufactures a complete line of RTD assemblies in all configurations used for plastics processing equipment. These assemblies are available in 2 and 3 wire configurations and can retrofit any existing RTD sensors being used. These assemblies can also be constructed with a copper tip to maximize heat transfer to the element and increase response time where tip sensitivity is important.
