Uncompensated, Non-Invasive Medical Pressure Sensor

The MPS-501G series pressure sensor is a packaged, un-amplified silicon Piezoresistive 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 Wheatstone bridge, results in a pressure proportional voltage.
