Melt pressure transducers and transmitters GEFRAN Melt sensors are pressure/temperature transducers and transmitters designed to be used in environments that reach very high temperatures and are able to measure media pressure up to 538°C. Based on two main constructive technologies (with filling fluid - extensimetric technology, and fluid free – silicon piezoresistive technology), Gefran high temperature pressure sensors are available in 4 different designs: rigid rod, flexible sheath, flexible with thermocouple, and exposed tip. Because they are highly immune to noise, these Melt pressure...

Fluid-free pressure sensor: IMPACT technology Series I (IMPACT) Melt sensors employ the piezoresistive principle: the pressure medium is converted into an electrical signal by a Wheatstone bridge built with 4 piezoresistors. The innovative IMPACT technology is patented by Gefran and is made up of 3 elements: The package: - guarantees mechanical transfer of the pressure to the chip without the use of transmission fluids - has been optimized to make the sensor stronger and more reliable (all parts in contact with the process and therefore subject to wear are up to 35 times stronger than...

Why choose GEFRAN Mercury-free solutions Concerned about environmental problems and in agreement with the RoHS directive, GEFRAN offers a wide range of "mercury-free" sensors:: • W series, with FDA-approved filling oil • K series, with NaK filling, declared GRAS • I series, completely fluid free Melt pressure transducers and transmitters GTP The new GTP coating, the result of Gefran research, ensures longer life for Gefran Melt sensors. Principal characteristics include: • low coefficient of friction • high hardness • high resistance to high temperatures • high resistance to chemical attack...
