IMPACT MELT PRESSURE TRANSMITTERS FOR
APPLICATIONS IN POTENTIALLY EXPLOSIVE
ATMOSPHERES IX SERIES 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 sensors are based on a piezoresistive technology, have been
checked following the NAMUR NE21 and NE43 recommendations and are in compliance with:
-EMC standard
-European RoHS standard
“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.
ADVANTAGES
- Total compatibility with the European RoHS Directive
- High strength
- Long life
- Working temperature: up to 350°C
- Excellent read stability over time
- Fast response time
MAIN FEATURES
• Pressure ranges:
0-100 to 0-1000 bar / 0-1500 to 0-15000 psi
• Accuracy: < ±0.25% FSO (H); < ±0.5% FSO (M)
• Standard threading 1/2-20UNF, M18x1.5; other versions on
request
• Other types of diaphragms are available on request
• Autozero function on board / external option
• 15-5 PH stainless steel diaphragm GTP+ coated
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
in the electronic transmitter 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.
Power with galvanic insulated barrier with 30V maximum voltage.
For version IX2, the thermocouple must be connected to EX-i circuits with
devices assigned to galvanic separation and with protection mode [EX
ia] IIC.
