OVERVIEW

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.

SPECIFICATION

• Reference conditions to DIN 16 086 and IEC 770/5.3.
• Bursting pressure 10 x full scale, 2000 bar max.
• Overload limit for ranges < 100 bar: 4 x full scale for ranges ≥ 100 bar: 2 x full scale.
• Storage temperature -40 to +85°C.
• Output 4 — 20 mA 2-wire.

FEATURES

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)
