Heavy Duty Pressure Transmitter
MBS1250
Principle of Operation
The pressure transmitter converts measured pressure
into a linear temperature compensated output signal
that is proportional to the transmitter supply voltage.
The output signal varies between 10 and 90% of the
supply voltage.
This output signal is well suited for direct connection
to an A/D converter provided that the transmitter and
the ratiometrically coupled A/D converter use the
same voltage reference. Danfoss PLUS+1® and other
microcontrollers use ratiometric A/D conversion.
Integrated Pulse Snubber
The heavy duty pressure transmitter with an
integrated pulse snubber is specially suited for
hydraulic applications where cavitation, liquid
hammer, or pressure peaks may occur. The pressure
peaks are often short but in extreme excess of the
measuring range of the transmitter.
The integrated pulse snubber is principally a nozzle in
the passage between the measured medium and the
pressure sensitive element of the transmitter
