MPS-500G(Uncompensated, Non–Invasive Medical Pressure Sensor)
The MPS-500G series pressure sensor is a packaged, unamplified
silicon piezo-resistive bridge. Requires external
amplification including sensor excitation, calibration and/or
temperature compensation. The sense element has four
pressure sensitive piezo resistors which are formed on the
diaphragm surface of a bulk micro machined silicon chip.
Applied pressure deforms a diaphragm causing piezoresistors
change their resistance. This change in four
resistors, which constitute a wheat-stone bridge, results in
a pressure proportional voltage.
The pressure sensor die is mounted in a pre-molded
plastic cavity package; dual in package (DIP), that has a
pressure port allowing pressure to act on the bottom side
of the die to sense the pressure medium (air). Binning of
packaged sensors are made possible by fully automated
customized testers.
