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.
