    27D Series

    27D series includes transmitters for differential pressures and level measurement. All series versions have analogue electronics, small sizes (typical housing Ø 27 mm) and fixed ranges (when possible to adjust zero and span, this can be done within ± 10 %).

    The transmitters are, as standard, installed on and supported by the process pipe or flanged on mating flange. For remote sensor version and when remote seal and capillary are supplied, a stainless steel bracket for wall mounting or for stand pipe 2” is also supplied.


    • 27D Series transmitters are used in industrial applications to measure absolute, relative and differential pressures and levels and also for flow rate. Fluids are liquids, gases and vapours and instrument’s body has been projected to sustain static pressures up to 75 bar.

    Our technical office is at your disposal for special applications.
