The "IMPACT" (I) series of Gefran are pressure transmitters, without transmission fluid, for using in high temperature environment
(662°F or 350°C).

Medium pressure is transferred directly to the sensitive silicon element through a thick diaphragm.

The micro structure includes the measurement membrane and piezo resistors.

Strain is transduced by a micro-machined silicon structure (MEMS). The operating principle is piezo resistive.

The minimum deflection required by the sensitive element makes it possible to use very robust mechanics.

The process contact membrane can be up to 15 times thicker than the membrane used in traditional Melt sensors.

The Impact (I) series is the right choice for Mercury free, and for absolute absence of filling fluid, for use in food and medical application.

Superior wear resistance is suitable with filled polymers.
High robustness towards the process: cold starts, multiple installation
Low thermal drift for Zero e Span signal : < 1%FS (68°F- 662°F)
High resistance to withstand to dynamic pressure
