Gefran SERIES AND PLc VERSION Data Sheet

IMPACT MELT PRESSURE TRANSMITTERS IE

SERIES AND PLc VERSION 4-20mA Output

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 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.

AUTOZERO FUNCTION

All signal variations in the absence of pressure can be eli­minated by using the Autozero function.
This function is activated by closing a magnetic contact
located on the transmitter electronics or by an external
contact.
The procedure is allowed only at zero pressure.
The Autozero function should be activated ONLY when the
sensor is completely installed on the system.

SELF DIAGNOSTICS

Below the conditions detected by the sensor self-diagnostics:

· Cut cable / device non connected / broken power supply, output <3.6mA

· Broken primary element / pin detachment, output >21mA

· Pressure above 200% of the span, output <3.6mA

· Pressure below the -30% of the span related to the zero value, output <3.6mA

· Voltage monitor in case of overvoltage/undervoltage/voltage variation in the electronics, output <3.6mA

· Program sequence error, output <3.6mA

· Overtemperature on the electronics, output <3.6mA

· Error on the primary element output or on the first amplification stage, output <3.6mA

· Activation threshold to be defined in the order code

· Rated carry current: 1A

· Rated voltage: 24Vdc ± 20%

NAMUR COMPLIANCE

The sensors are tested according to Namur NE21 recommendations.
The same compatibility is valid for the NE43 Namur recommendation with the following sensor behaviour in case of
breakdown:

· Cut cable: breakdown information as the signal is <3,6mA

· Device not connected: breakdown information as the signal is <3,6mA

· Broken power-supply: breakdown information as the signal is <3,6mA

or in case of performance problems:

· most common failures on primary sensors: the signal goes to>21mA

Note: in all the remaining situations, the output signal is always included between 3,6 and 21mA.

Recommendation: the error level set by the customer (e.g. maximum pressure value) has to be inside
the nominal range

The diagram shows the optimum ratio between load and power supply
for transmitters with 4…20mA output.
For correct function, use a combination of load resistance and voltage
that falls within the two lines in the graph above.

AUTOZERO FUNCTIONLOAD DIAGRAM

The Autozero function is
activated through a magne­tic contact (external magnet
supplied with the sensor).
For the external Autozero
version short-circuit the cor­rect pin.
