Melt Pressure
Melt Pressure Transducers (MPT) are based on strain gauge technology and formed with a full Wheatstone bridge circuit. Melt pressure transducer fills the high temperature application gap (≧400°C) at where other pressure sensors would possibly fail, e.g. plastics extrusion, injection and blow moulding industries. MPT has high degree of accuracy, stability and repeatability at high operation temperature and is ideal for extruder melt pressure measurements.

Melt pressure transducer using Piezoresistive strain gauge technology can convert medium pressure into an electrical signal output. Instead of using conventional transmission line filled with mercury or special types of oil, pressure values are transmitted mechanically via a rigid stem which is attached to the sensing element using a Wheatstone bridge circuit formed by 4 strain gauges on a micro-machined silicon structure in the sensor.
Melt Pressure Transducers with flexible extension stem and mounted manometers are available for selection. Melt pressure transmitters offer a wide range from 0/10 bar to 0/2000bar with high accuracy up to 0.3%F.S. and 150% overload pressure capabilities.
