Pressure transmitter for marine applications
MBS 3100 and MBS 3150
IC.PD.P20.2O.02 | 520B8244 | 1
The compact ship approved pressure transmitters
MBS 3100 and MBS 3150 are designed for use in
almost all marine applications.
MBS 3150 with integrated pulse-snubber is
suitable in marine applications with severe
medium inuences like cavitation, liquid hammer
or pressure peaks and oers a reliable pressure
measurement, even under harsh environmental
conditions.
The exible pressure transmitter programme
covers, absolute or gauge (relative) versions,
measuring ranges from 0 – 1 to 0 – 600 bar. A
wide range of pressure and electrical connections
are available.
Excellent vibration stability, robust construction,
and a high degree of EMC/EMI protection
equip the pressure transmitter to meet the most
stringent industrial requirements.

Application and media
conditions (MBS 3150)
Application
Cavitation, liquid hammer and pressure peaks
may occur in liquid lled hydraulic systems
with changes in ow velocity, e.g. fast closing
of a valve or pump starts and stops.
The problem may occur on the inlet and outlet
side, even at rather low operating pressures.
Media condition
Clogging of the nozzle may occur in liquids
containing particles. Mounting the transmitter
in an upright position minimizes the risk of
clogging, because the ow in the nozzle is
limited to the start-up period until the dead
volume behind the nozzle orice is lled.
The media viscosity has only little eect on the
response time. Even at a viscosities up to 100 cSt,
the response time will not exceed 4 ms.
