MELT PRESSURE SENSORS HIX THE MELT TRANSDUCER FOR POLIMER PRODUCTION PLANT The HIX series of Gefran, are pressure transmitters for using in High temperature environment and specifically designed for melt pressure measurement and available mainly to be used large industrial process plants, typically extruders for polymers or equipment for R&D purposes according to the European Directive 2011/65/EU (see informative note RoHS II). Gefran’s HIX series are pressure transmitters with HART communication protocol for use in high temperature environments in potentially explosive areas.

The peculiarity of this series is the ability to read the fluid temperature up to 350° C, where the main characteristic of the “IMPACT” sensors is that they do not contain any transmission fluid inside. 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 membrane in contact with the process is very sturdy and can be up to 15 times thicker than the membranes used in traditional melt sensors. • IMPACT: the most performing fluidfree transducer...

MELT PRESSURE SENSORS TRANSMISSION 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 process contact diaphragm...
