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 10-
90% of supply
• Excellent shock and vibration robustness
• Reverse polarity protection
• With build-in clipping function and self-
diagnostic features on request
• Enclosure and wetted parts of stainless steel
(AISI 316L)
• EU RO Mutual Recognition
• Customer specic versions on request
• For use in Zone 2 explosive atmosphere

Full-scale span (FSS)
Full-Scale Span (FSS) is the dierence between
the upper limit and the lower limit of the
pressure range.
(e.g. for pressure range -30 – 30 mbar, FSS = 60
mbar.)
