Heavy-Duty Pressure Transmitter

MBS2250 SAE

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
