Description
The MPX10 and MPXV10GC series devices are silicon piezoresistive pressure sensors providing a very accurate and linear voltage output — directly proportional to the applied pressure. These standard, low cost, uncompensated sensors permit manufacturers to design and add their own external temperature compensation and signal conditioning networks. Compensation techniques are simplified because of the predictability of Freescale’s single element strain gauge design. Figure 1 shows a schematic of the internal circuitry on the stand-alone pressure sensor chip.

Uncompensated Pressure Sensor Schematic VOLTAGE OUTPUT VERSUS APPLIED DIFFERENTIAL PRESSURE The output voltage of the differential or gauge sensor increases with increasing pressure applied to the pressure side (P1) relative to the vacuum side (P2). Similarly, output voltage increases as increasing vacuum is applied to the vacuum side (P2) relative to the pressure side (P1). Table 1.
