Customer benefits

  • Process reliable

The measuring device was designed and certified in conformity with ATEX directives. Its completely welded measuring system does not require seals and ensures maximum process safety. Its core is a piezoresistive measuring cell that is safe, reliable, and temperature resistant due to its high overload resistance and longevity.

  • Versatile

A broad spectrum of measuring ranges as well as a large number of process connections guarantee variant diversity that can be specifically adapted to any application. As an option, level probe versions (extra code 406 and 407) are available.


  • Sterilizers
  • Autoclaves
  • Flour and corn silos (for dust deposits)

Level and filling level measurement for

  • Water and sewage water management

Product comparison


The pressure transmitter type 404753 measures the pressure of non-aggressive and aggressive gasses, vapors, liquids, and dust. The device operates according to the piezoresistive measuring principle. The output signal is a load-independent direct current which is linearly proportional to the input pressure.
The pressure transmitter type 404753 meets the following requirements of explosion group II

  • In explosive area (due to gas ->Gas) of zones 1 and 2.
    Here the pressure connection (process connection) can even be fitted to zone 0.
  • In the explosive area (due to dust -> Dust) of zones 21 and 22.

EC-type examination certificate of the pressure transmitter is as follows: SNCH 03 ATEX 3545.
