High temperature level gauge Melt Pressure sensor
n Overview
The VPH Series High Temperature Melt Pressure transducer/transmitters are widely used in the plastics, chemical fiber, rubber, boiler industry high temperature melt pressure measurement and control. The product is digested and absorbed domestic and foreign similar products technology, uses the high-quality sensors and components meticulous production, with a stable and reliable performance, high accuracy, good dynamic, small temperature drift, high temperature resistance, etc. Can match our smart meter VM201, VM202, VM302 supporting the use, consisting of high-reliability, high-temperature melt pressure measurement and control system.
Do not need any changes, can directly match the produce such as Italy Gefran, American DYNISCO.
