The compact high temperature pressure

transmitter is designed for use in almost all

marine applications, and oers a reliable

pressure measurement, even under harsh

environmental conditions.

The exible pressure transmitter programme

covers dierent 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 exellent vibration stability,

and a high degree of EMC / EMI protection

equip the pressure transmitter to meet the

most stringent marine requirements.

Features

• Designed for use in severe maritime

environments

• For medium and ambient temperatures up to

125 °C

• All standard output signals:

◦ Ratiometric 10 - 90% of supply

◦ 4 – 20 mA

◦ 0 – 5 V, 1 – 5 V, 1 – 6 V, 0 – 10 V

• Enclosure and wetted parts of AISI 316L

• A wide range of pressure and electrical

connections

• Fully digitally compensated

• For use in ATEX Zone 2 explosive

atmospheres

• UL approved

Data Sheet

Pressure transmitter

Type MBS 3300 and MBS 3350

For high temperature marine applications

Applications

Application and media conditions (MBS 3350)

Pulse-snubber

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 startup period until the dead volume

behind the nozzle orice is lled.

The media viscosity has only little eect on the response time. Even at a viscosities up to 100 cSt, the response time

will not exceed 4 ms.
