50 kPa Uncompensated Silicon Pressure Sensors
The MPX50 silicon piezoresistive pressure sensor provides 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 Ratiometric to Supply Voltage Easy to Use Chip Carrier Package Options 60 mV Span (Typ) Differential and Gauge Options ± 0.25% (Max) Linearity Application Examples Air Movement Control Environmental Control Systems Level Indicators Leak Detection Medical Instrumentation Industrial Controls Pneumatic Control Systems Robotics Figure 1 shows a schematic of the internal circuitry on the stand–alone pressure sensor chip.
