High Temperature Melt Pressure Transducer (Melt Pressure Sensor)
Product Introduction:
SAND PT4XX6 series pressure transducers are ideal for the measurement of melt pressure in extrusion processes at temperatures up to 400 . This series are produced with special materials and alloyed elastic diaphragm together with delicate processing and debugging. The main characteristics are high accuracy and small zero and span shifts caused by changes in process temperatures.
