MBS 8200 is a series of compact pressure

transmitters developed to withstand the pressure

pulsations and vibrations known in mobile and

industrial hydraulic applications.

A new technology combining piezo resistive

sensor element and programmable gain

ampliers makes the MBS 8200 the obvious

choice for applications demanding highest

accuracy and insensitiveness against temperature

variations. Further this technology enhances the

functional safety by limiting the output signal

at excess pressure conditions, it allows excellent

sink/source capabilities and it leave the pressure

transmitters unaected by electromagnetic elds

up to 100 V/m.

MBS 8250 with integrated pulse-snubber is

designed for use in tough applications with

severe media inuences like cavitation, liquid

hammer or pressure peaks.

Application

Cavitation, liquid hammer and pressure peaks may

occur in 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.

The media viscosity has only little eect on the

response time. Even at viscosities up to 100 cSt,

the response time will not exceed 4 ms.
