700 kPa Uncompensated Silicon Pressure Sensors
The MPX700 series device is a silicon piezoresistive pressure sensor providing a very accurate and linear voltage output — directly proportional to the applied pressure. This standard, low cost, uncompensated sensor permits manufacturers to design and add their own external temperature compensating and signal conditioning networks. Compensation techniques are simplified because of the predictability of Motorola’s single element strain gauge design. Features Low Cost Patented, Silicon Shear Stress Strain Gauge Design Linearity to ± 0.5% (Max) Linearity Easy to Use Chip Carrier Package Options Ratiometric to Supply Voltage 60 mV Span (Typ) Absolute, Differential and Gauge Options Application Examples Environmental Control Systems Pneumatic Control Systems Appliances Automotive Performance Controls Medical Instrumentation Industrial Controls Figure 1 illustrates a schematic of the internal circuitry on the stand–alone pressure sensor chip.
