I Series (Impact)

I3 Melt Pressure Transmitters – mV/V 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.

  • Pressure ranges:

IN Melt pressure transmitters – Voltage 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-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.

Application:

  • 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
