The TER / TEFE / SEFE / SERP series from DwyerOmega (Omega Engineering) is a line of rugged thermocouple probes designed specifically for plastic processing applications. These probes mount directly into extruder heads or die adapters, with their sensor tip immersed in the molten plastic to provide accurate, real-time temperature measurement. Built with 316 stainless steel for durability and corrosion resistance, they support service temperatures up to 900 °F (480 °C). Customers can choose from single- or dual-element designs, with either rigid plug (TER / SERP) or flexible extension (TEFE / SEFE) configurations. Compatible with J, K, T, or E thermocouple calibration types and available in a variety of “A” and “B” dimension sizes, these probes are ideal for high-demand extrusion and injection molding environments.
