The compact OEM pressure transmitter
programme is designed for use in severe
hydraulic applications. The programme consists
of two series:
• MBS 1600 – without integrated pulse-snubber
• MBS 1650 – with integrated pulse-snubber
The integrated pulse-snubber offers a high
degree of protection against cavitations and
liquid hammer, and the well thought out design
results in excellent vibration stability and an
exceptional robustness. The high degree of EMI
protection equips the pressure transmitter to
meet most requirements.
Features • Designed for use in severe OEM applications
• For medium and ambient temperatures
up to 125 °C
• All standard output signals:
4 – 20 mA, 1 – 5 V, 1 – 6 V, 0 – 10 V
• Wetted parts made of stainless steel
• Immunity to electrical noise from VFD
• Immunity to direct coupled transients
• Immunity to pulse magnetic field
• Mis-wire protected
• Short circuit protected
• A wide range of pressure and electrical
connections
• EMC protection up to 100 V/m
• MTTFd > 100 years

Pulse-snubber in MBS 1650 Application
Cavitation, liquid hammer and pressure peaks
may occur in liquid filled 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.
The media viscosity has only little effect on the
response time. Even at viscosities up to 100 cSt,
the response time will not exceed 4 ms.
