The compact pressure transmitter, type MBS
3000, is designed for use in industrial and
hydraulic applications, and oers a reliable
pressure measurement, even under harsh
environmental conditions.
The compact heavy duty pressure transmitter
MBS 3050 with integrated pulse-snubber is
designed for use in hydraulic applications with
severe medium inuences like cavitation, liquid
hammer or pressure peaks 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. 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.

Applications
Application and media conditions for MBS 3050
1
Pulse-snubber
Application for MBS 3050
Cavitation, liquid hammer and pressure peaks may occur in hydraulic systems with changes in ow velocity, e.g. fast
closing of a valve or when a pump starts and stops.
The problem may occur on the inlet and outlet side of the application, even at rather low operating pressures.
Media condition for MBS 3050
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 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.
