Overview
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) and the operating principle is piezoresistive.
This new series “ILI” with “IO-Link” digital output is a Smart device specifically designed to meet the requirements of “Industry 4.0” environment, with auxiliary information suitable to prevent machine downtime.
The main characteristic of “IMPACT” sensors is that they do not contain any transmission fluid.
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.
Suitable for Functional Safety applications thanks to PLd and
SIL2 approvals.
