Description
Gefran High Temperature Pressure ME (Mercury Filled) Series Sensors are pressure transducers or transmitters for using in High temperature environments. The main characteristic of this series is the capability to read temperature of the media up to 400°C or 752°F. The constructive principle is based on the hydraulic transmission of the pressure. Moreover, the fluid-filled system assures temperature stability. The physical quantity is transformed in a electrical measure by means the thick film strain-gauge technology. The SIL2 certified version makes the product suitable for use in the Functional Safety applications, particularly in the process plants for the production of polymers, where it is an essential requirement.

Gefran Key Advantages of Melt Pressure Sensors
The use of melt probes is indispensable in extrusion processes as they contribute:
- To the safety of the system when used to prevent an uncontrolled rise in machine pressure.
- To improving the performance of production with their ability to keep flow-rate stable and optimal.
Melt Sensors are normally used in pressure reading:
- along the cylinder to check its performance during the development and design of the screw
- in the filter changer to check its cleanliness
- before and after the gear pump to keep the flow rate constant
- in the head for closed-loop pressure control
The Gefran Melt pressure sensor is ideal for applications in the polymer production and processing industry.
