Vaisala BAROCAPâ Barometer PTB110 is designed both for accurate barometric

pressure measurements at room temperature and for general environmental pressure

monitoring over a wide temperature range.

Vaisala BAROCAP Technology

PTB110 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

detection principle.

Applications

PTB110 is suitable for a variety of

applications, such as environmental

pressure monitoring, data buoys, laser

interferometers, and agriculture and

hydrology. The compact PTB110 is ideal

for data logger applications as it has low

power consumption. The external On/Off

control is practical when electricity

supply is limited.

Accuracy and Stability

The excellent long-term stability of

the barometer minimizes or even

removes the need for field adjustment in

many applications.
