1.1. General information
This manual refers to the following products:
ILI and must be kept near the equipment for easy reading and consultation.
It must be read, understood, and strictly follow in order to avoid and prevent accidents and/or malfunctions.
Gefran will not be liable for any injury to people and/or damage to property deriving from disregard of this manual.
1.2. Copyright
Any reproduction of this document, even partial or for internal use, requires Gefran's approval.
1.3. Correct use
Gefran Melt pressure sensors are designed and built to measure the pressure and temperature variable of melted plastic at different
temperatures according to the filling fluid used.
The correct temperature range is:
• Up to 350°C
If the sensors are used as a safety component in accordante with the Machinery Directive, the equipment builder must take all
necessary precautions to ensure that any malfunctions of the Melt pressure sensor do not injury to people and/or damage to property.
Installation and maintenance must only be carried out by suitably skilled and qualified personnel.
2.1. IMPACT IO-LINK MODELS
IMPACT "ILI" series of Gefran, are pressure transmitters, without transmission fluid, for using in High temperature process environment
(up to 350°C). Pressure is transduced by a micro-worked silicon structure (MEMS) and the operating principle is "piezoresistive".
"IMPACT" is Gefran's exclusive series of high-temperature pressure sensors that use the piezoresistive principle.
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 sensitive element, directly positioned behind the contact 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 15 times thicker than the membrane used in traditional Melt sensors.
Supplied in 2 different configurations, rigid stem, and rigid + flexible and 4 mechanics, single and modular fixed and single and
modular floating, the Melt sensors of GEFRAN are able to meet all installation requirements in the field.
The coverage relative to the pressures that can be detected by the sensor is almost total; we start from the probe with a minimum
range of 0-10 bar to arrive at a version with a scale of 0-1000bar. All models in the catalogue can be supplied in two different accuracy
classes; in particular class M, with accuracy 0.5%FS and class H, with 0.25%FS accuracy.
Thanks to PLd and SIL2 approvals, this product is suitable for Functional Safety applications.
2.2. Transducer General Information
