ILM Mercury filled – IO-Link digital output – SIL2 – PLd



  • The ILM Performance Level "d"/SIL2 series of Gefran are pressure transmitters for use in high-temperature environments with a digital IO-Link output interface.
  • The constructive principle is based on the hydraulic transmission of the pressure.
  • This new series ILM with "IO-Link" interface is a Smart device specifically designed to meet the requirements of "Industry 4.0" environment, with auxiliary information suitable to prevent machine downtime.
  • The main characteristic of this series is the capability to read the temperature of the media up to 400°C (750°F).
  • In addition, with PLd and SIL2 approvals, the ILM series is the best solution for "Functional Safety" applications.


  • Pressure ranges from: 0-17 to 0-2000 bar / 0-250 to 0-30000 psi
  • Accuracy: < ±0.25% FS (H); < ±0.5% FS (M)
  • 1/2-20UNF, M18x1.5 standard threads
  • 15-5 PH diaphragm with GTP+ coating
  • 17-7 PH corrugated diaphragm with GTP+ coating for ranges below 100bar/1500psi.
  • IO-Link digital output, ready for "Industry 4.0"
  • Rangeabilty: 3:1
  • PLd and SIL2 approvals for Functional safety
  • Autozero function
  • Auxiliary information over IO-Link protocol
