Pressure MPX53 Freescale Semiconductor Rev 7, 05/2009 50 kPa Uncompensated MPX53 Silicon Pressure Sensors Series The MPX53 series silicon piezoresistive pressure sensors provide a very 0 to 50 kPa (0 to 7.25 psi) accurate and linear voltage output, directly proportional to the applied 60 mV Full Scale Span pressure. These standard, low cost, uncompensated sensors permit (Typical) manufacturers to design and add their own external temperature compensating and signal conditioning networks. Compensation techniques are simplified because of the predictability of Freescale s single element Application Examples strain gauge design.

Device is ratiometric within this specified excitation range. Operating the device above the specified excitation range may induce additional error due to device self-heating. 3. Full Scale Span (V ) is defined as the algebraic difference between the output voltage at full rated pressure and the output voltage at the FSS minimum rated pressure. 4. Offset (V ) is defined as the output voltage at the minimum rated pressure. OFF 5. Response Time is defined as the time for the incremental change in the output to go from 10% to 90% of its final value when subjected to a specified step change in pressure. 6. Warm-up Time is defined as the time required for the product to meet the specified output voltage after the pressure is stabilized. 7. Offset stability is the products output deviation when subjected to 1000 hours of Pulsed Pressure, Temperature Cycling with Bias Test. MPX53 Sensors 2 Freescale Semiconductor
