The pressure transmitter series HDA 7400 combines excellent technical specifications with a highly compact design.

To begin with, the HDA 7446 is for use for OEM applications e.g. in mobile applications. What’s more, a strain gauge sensor cell is the basis for a robust, long-life pressure transmitter.

Also, various pressure ranges between 0 .. 40 bar and 0 .. 600 bar provide versatility when adapting to particular applications.

Moreover, for integration into modern controls (e.g. with PLC), the analogue output signals 4 .. 20 mA or 0 .. 10V are also available on the standard version. Other output signals are available on request.


  • An accuracy ≤ ± 0.5 % FS typ.
  • A highly robust sensor cell
  • A very compact design
  • A very small temperature error
  • Also, it has excellent EMC characteristics
  • An excellent durability
