The Vaisala BAROCAP® Barometer
PTB110 is designed both for accurate
barometric pressure measurements
at a room temperature and for
general environmental pressure
monitoring over a wide temperature
The PTB110 barometer uses the
Vaisala BAROCAP® Sensor, a silicon
capacitive absolute pressure sensor
developed by Vaisala for barometric
pressure measurement applications.
The sensor combines the outstanding
elasticity characteristics and
mechanical stability of single-crystal
silicon with the proven capacitive
Accuracy and stability
The excellent long-term stability of
the barometer minimizes or even
removes the need for fi eld adjustment
in many applications.
The PTB110 is suitable for a variety of
applications, such as environmental
pressure monitoring, data buoys,
laser interferometers, and in
agriculture and hydrology.
The compact PTB110 is especially
ideal for data logger applications as it
has low power consumption. Also an
external On/Off control is available.
This is practical when the supply of
electricity is limited.
