Pressure transmitter

Type MBS 9300

For marine applications

Compact pressure transmitter programme, MBS 9300 gauge version is designed for use in marine applications e.g. crankcase and turbocharger €lters monitoring as well as applications within level measurement.

The programme covers 4 – 20 mA and ratiometric 10-90% of supply output signals, pressure span from 40 – 400 mbar as well as bidirectional ranges.

Excellent vibration stability, robust construction, and a high degree of EMC/EMI protection equip the pressure transmitter to meet the most stringent industrial requirements.

Features

• Compact design

• Full scale span from 40 – 400 mbar

◦ bidirectional ranges available, e.g. -40 – 70 mbar etc.

◦ lowest zero point –150 mbar ◦ max full scale 250 mbar

• Digital temperature compensated

• Output signals 4-20 mA and Ratiometric 1090% of supply

• Excellent shock and vibration robustness

• Reverse polarity protection

• With build-in clipping function and selfdiagnostic features on request

• Enclosure and wetted parts of stainless steel (AISI 316L)

• EU RO Mutual Recognition

• Customer speci€c versions on request

• For use in Zone 2 explosive atmosphere
