Pressure Transmitter
Type MBS 8200 and MBS 8250
For Wind Turbine Applications
MBS 8200 is a series of compact pressure
transmitters developed to withstand the
pressure pulsations and vibrations known in
wind turbine applications.
A new technology combining piezo resistive
sensor element and programmable gain
ampliers 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 unaected by
electromagnetic elds up to 100 V/m.
MBS 8250 with integrated pulse-snubber is
designed for use in hydraulic applications with
severe media inuences like cavitation, liquid
hammer or pressure peaks, and oers a reliable
pressure measurement, even under harsh
environmental conditions.
Features
• Designed for use in harsh industrial
environments
• EMC protection 100 V/m
• For media and ambient temperatures up to
125 °C
• Reverse polarity protected
• Version with integrated pulse-snubber
• Protected against cavitation, liquid
hammering and pressure peaks
• Enclosure and wetted parts of AISI 316L
• Digitally temperature calibrated
• RoHS conformity

Applications
Applications (MBS 8250)
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.
Media conditions (MBS 8250)
Clogging of the nozzle may occour in liquids containing particles. Mounting the transmitter in an upright position
minimizes the risk of clogging, because the ow in the nozzle is restricted to the start-up period when the dead
volume behind the nozzle lls, and furthermore because the nozzle orice is relatively big (0.4 mm). The media
viscosity has only little eect on the response time. Even at viscosities up to 100 cSt, the response time will not
exceed 4 ms.
