Melt Pressure Transducers

DWEL Melt Pressure Transducers and Transmitters are designed for accurate melt pressure measurement in extrusion and polymer processes, capable of withstanding temperatures up to 400°C. Manufactured with high-quality materials and alloyed elastic diaphragms, these devices undergo precise processing and calibration for exceptional reliability. Key features include external zero clearance or an optional magnetic auto-zero clearance, ensuring stable performance and minimal shifts in zero and span, even with temperature variations. Known for their high accuracy and stability, DWEL transducers are widely used in plastic extrusion lines, as well as the polymer and fiber industries. They provide an excellent alternative to brands like Dynisco, Gefran, and Graeff.

DWEL RPT Series Melt Pressure Transmitters are equipped with high-performance digital chips and feature a circuit design that meets SIL2 and PL 'c' safety performance standards. The transmitters are equipped with relay outputs that control the range limits, ensuring the safety of extrusion equipment and production lines. This design helps to prevent equipment damage and reduce the risk of unpredictable safety accidents due to pressure overload. The RPT Series is an excellent alternative to brands like Dynisco, Gefran, and Graeff.

DWEL XPT Series are explosion-proof melt pressure transmitters with 4~20 mA output and HART protocol, specifically designed for use in hazardous environments. Constructed with a full stainless steel welded structure, this series offers both thread and flange installation options. The use of high-performance core components ensures exceptional measurement accuracy and reliability. The XPT Series is widely utilized for melt pressure control in high-precision polymer extrusion equipment, production lines, and laboratory instruments. It serves as an ideal replacement for Dynisco, Gefran, and Graeff.

DWEL melt pressure transducers and transmitters are ideal for the measurement of melt pressure in extrusion and polymer processes at temperatures up to 400℃. This series are produced with high quality materials and alloyed elastic diaphragm together with delicate processing and debugging. The main characteristics are stable performance, high accuracy and small zero and span shifts caused by changes in process temperatures. It´s widely used in plastic extrusion production line,polymer and fiber industries. It’s an ideal option to replace Dynisco,Gefran and Graeff.
