The “IMPACT” series of Gefran, are pressure transmitters, without transmission fluid, for using in High temperature environment (350°C).

Medium pressure is transferred directly to the sensitive silicon element via a thick diaphragm. Strain is transduced by a micro-worked silicon structure (MEMS). The operating principle is piezoresistive. “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 con-tact membrane, is realised in silicon through 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 membrane can be up to 35 times thicker than the membrane used in traditional Melt sensors.
