Micatrone MF-PFA Differential Pressure Transmitter

The Micatrone MF-PFA low differential pressure transmitter is an accurate programmable differential pressure transmitter, specifically designed towards demanding ventilation and cleanroom applications.  With user selectable analogue output options, relay alarms, on board visual and audible alarms, PID control and a local alphanumeric display, this pressure and flow transmitter is a high end, all round differential pressure monitoring system for many ventilation applications.

Such is the pedigree of the Micatrone MF-PFA, that it has been awarded EMPHASIS approval.  The Micatrone MF-PFA supplied with a 5 valve maintenance manifold is the HVAC transmitter of choice for many of the UK Nuclear Site Licenced Facilities.  This allows in-situ calibration without the need to remove the instrument physically.


Micatrone MF-PFA instrument specifications include….

  • An uncertainty of within 0.5% full pressure range plus 0.5Pa
  • Pressure ranges start as low as 0…100Pa plus turndown function
  • Max static pressure of 50KPa
  • 2x analogue outputs 2x Relay contacts
  • Analogue outputs in voltage or mA (user selectable)
  • SQRT Extraction function for airflow measurement
  • Optional purging function for particulate prone airflow applications
  • Optional auto-zero facility, particularly beneficial for low pressure ranges
  • EMPHASIS Approval for the UK Nuclear Authority
  • PID Control for fan control applications
  • Optional MODBUS over RS-485 communications
  • Each unit is supplied with its own factory calibration certificate
