Piezo-resistive pressure sensors

• The 142PC series pressure sensors are piezo-resistive devices with semiconductors, which are perfectly suited to exact pressure measurements.
• A silicon membrane generates a linear output signal proportional to the pressure, with no ripple.
• The advanced technology of these sensors gives them great sensitivity, high reliability, low hysteresis, very short response times and long stability over time.
• Two types:
  - absolute: measurement relative to a perfect vacuum
  - differential: measurement of the difference between two pressures.
