Barometric Pressure Sensor Vaisala PTB110
The Vaisala BAROCAP® Barometer PTB110 is designed both for accurate
barometric pressure measurements at a room temperature and for gen-
eral environmental pressure monitoring over a wide temperature range.
Vaisala BAROCAP® technology
The PTB110 barometric pressure sensor uses the Vaisala BAROCAP® sen-
sor, 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 detection principle.

Accuracy and stability
The excellent long-term stability of the barometric pressure sensor minimizes or even removes the need for eld ad-
justment in many applications.
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.
