Pressure transmitter for marine applications
DST P30M
The compact high temperature pressure
transmitter is designed for use in almost all
marine applications, and offers a reliable pressure
measurement, even under harsh environmental
conditions.
The flexible pressure transmitter program covers
different output signals, absolute or gauge
(relative) versions, measuring ranges from 0 – 1
to 0 – 600 bar and a wide range of pressure and
electrical connections.
A robust design, an excellent vibration stability,
and a high degree of EMC / EMI protection
equip the pressure transmitter to meet the most
stringent marine requirements.
Running a powerful ARM-based microcontroller,
the DST P30M offers diagnostic functions and
performance features.

Technical data
Application
Cavitation, liquid hammer and pressure peaks
may occur in liquid filled hydraulic systems with
changes in flow 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 flow in the nozzle is
limited to the start-up period until the dead
volume behind the nozzle orifice is filled.
The media viscosity has only little effect on the
response time. Even at a viscosities up to
100 cSt, the response time will not exceed 4 ms.
