BAROCAP’s Unique Benefits
Low hysteresis, high
repeatability
Superior long-term stability
Tolerates harsh conditions
First introduced in 1985, Vaisala BAROCAP
®
is a silicon-based micromechanical pressure sensor
that offers reliable performance in a wide variety of applications, from meteorology to industrial
measurements. Combining two powerful technologies – single-crystal silicon material and
capacitive measurement – BAROCAP sensors feature low hysteresis combined with excellent
accuracy and long-term stability.
How It Works
BAROCAP is a micromechanical
sensor that uses dimensional changes
in its silicon membrane to measure
pressure. As the surrounding
pressure increases or decreases, the
membrane bends, thereby increasing
or decreasing the height of the
vacuum gap inside the sensor. The
opposite sides of the vacuum gap act
as electrodes, and as the distance
between the two electrodes changes,
the sensor capacitance changes.
The capacitance is measured and
converted into a pressure reading.
The BAROCAP sensor’s properties
– good elasticity, low hysteresis,
excellent repeatability, low
temperature dependence, and
superior long-term stability – are
the result of its single-crystal silicon
material. The capacitive structure
gives the sensor its wide dynamic
range and provides a built-in
mechanism for overpressure blocking.
Typical Applications for
Barometric Pressure
Measurement
Barometric pressure measurement
has a wide variety of applications
within meteorology. Pressure data is
required for estimating the amount
of precipitable water vapor in the
atmosphere. Typical applications
include weather stations, data buoys,
GPS meteorology, and environmental
data logging. Barometric pressure
measurement is also used in hydrology
and agrology applications.
Barometric pressure data is also
required in several industrial
applications. It is measured in pressure-
sensitive industrial equipment, such as
laser interferometers and lithography
systems, aviation applications, and
in exhaust-gas analysis. Metrological
applications include laboratory
pressure standard measurements
and environmental monitoring in
calibration laboratories.
