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.

  • As for absolute absence of filling fluid , the I series is the right choice for Mercury free, food and medical application.
  • Superior  wear reasistence:  suitable with filled polymers
  • High resistance  to withstand to dynamic pressure
  • High robustness towards the process :cold starts ,multiple installation
  • Low thermal drift for  Zero e Span signal : < 1%FS  (20°C-350°C)
  • 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 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 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.
