Level ProbePressure Transmitter or Level Probe
The type 404753 pressure transmitter measures the pressure in both corrosive and non-corrosive gases, vapors, liquids and dusts. The transmitter operates on the piezoresistive measuring principle. The output signal is a DC current that is proportional to the input pressure.
The type 404753 pressure transmitter fulfills the following requirements for equipment group II
– in Zone 1 and 2 areas with an explosion hazard arising from gas (Gas).
The pressure connection (process connection) may, however, also be mounted on to
zone 0.
– in Zone 21 and 22 areas with an explosion hazard arising from dust (Dust)
