IN IMPACT fluid free – Voltage output

IN

Overview

  • The "IMPACT" series of Gefran are pressure transmitters, without transmission fluid, for use in high-temperature environments (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 microstructure 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 the absolute absence of filling fluid, the I series is the right choice for Mercury-free, food and medical application.
  • Superior wear resistance: 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)
