Barometric Pressure Measurement
Capacitive pressure measurement
The Vaisala BAROCAP® Sensor combines two powerful techniques: the use of
single crystal silicon as sensor material, and the capacitive measurement
principle. Silicon offers good elasticity, low hysteresis, excellent
repeatability, small temperature dependence and superior long-term stability.
Thanks to the capacitive pressure sensor structure, the sensor has a wide
dynamic range and a built-in overpressure blocking mechanism.
Applications
Vaisala’s barometers offer excellent performance in a variety of
applications. In meteorology, barometric pressure is measured in weather
stations, data buoys, GPS meteorology and other environmental data logging. In
industry barometric pressure data is needed for pressure sensitive industrial
equipment, such as laser interferometers and litography systems, aircraft
applications and engine test benches. In actual metrology typical applications
include laboratory pressure standard measurements and calibration laboratory
monitoring.
