BEYOND TECHNOLOGY MELT PRESSURE SENSORS HART HIX THE MELT TRANSDUCER FOR POLIMER PRODUCTION PLANT The HIX series of Gefran, are pressure transmitters for usingin High temperature environment and specifically designed for melt pressure measurement and available mainly to be used in large-scale fixed installations or in large-scale stationary industrial tools, typically extruders for polymers or equipment for R&D purposes according to the European Directive 2011/65/EU (see informative note RoHS II). The HIX series of Gefran are pressure transmitters with HART communication protocol for using...

The main characteristic of this series is the capability to read temperature of the media up to 350°C. The main characteristic of “IMPACT” sensors is that they do not contain any transmission fluid. The sensitive element, directly positioned behind the contact membrane, is realised in silicon through microprocessing techniques. The micro structure includes the measurement membrane and piezoresistors. The process contact membrane can be up to 15 times thicker than the membrane used in traditional Melt sensors. • IMPACT: the most performing fluidfree transducer • Wide pressure ranges from...

MELT PRESSURE SENSORS IMPACT MELT PRESSURE SENSORS FLUID FREE TECHNOLOGY IMPACT is Gefran’s exclusive series of high-temperature pressure sensors that use the piezoresistive principle. The main characteristic of IMPACT sensors is that they do not contain any transmission fluid. The sensitive element, directly positioned behind the contact diaphragm, is made from silicon by means of microprocessing techniques. The micro structure includes the measurement membrane and piezoresistors. The minimum deflection required by the sensitive element makes it possible to use very robust mechanics. The...
