MPT Series Melt Pressure Transducer And Transmitter

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.
