Fluid Free Melt Pressure Transducers and Transmitters

ILI IMPACT Fluid Free - IO-Link digital Output - SIL2 - PLd

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.

HIX IMPACT fluid free - HART - ATEX - SIL2 - PLd

The "IMPACT" series sensors are pressure transmitters, without transmission fluid, designed for use in high temperature environments (350°C).

The media pressure is transferred through a thick membrane directly to the silicon sensing element.

The main characteristic of the "IMPACT" sensors is that they do not contain any transmission fluid inside.

The sensing element, directly positioned behind the contact membrane, is made by silicon through micromachining techniques and the minimum deflection necessary to the sensing element, allows the use of very strong mechanics, with a process membrane 15 times thicker than the membranes used in traditional Melt sensors.

The new "HIX" series combines Impact technology with Smart/Hart digital technology, with in addition the "Atex" certification for use in hazardous areas, and SIL2 and PLd certifications for functional safety applications.

All these features make the “HIX” series particularly suitable for applications in process plants especially for the production of polymers, fibres and resins.

IE PLc IMPACT Fluid free - Output 4…20mA

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-machined silicon structure (MEMS). The operating principle is piezoresistive.

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 15 times thicker than the membrane used in traditional Melt sensors.
