Product comparison


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

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

EC design test certificate of the pressure transmitter: SNCH 03 ATEX 3545.
