Vaisala PTB330 Digital Barometer

Digital Barometer PTB330

This PTB330 barometer - designed for a wide range of high-end atmospheric pressure measurement - is based on the Vaisala BAROCAP® Sensor. It is a Vaisala in-house, silicon capacitive, absolute pressure sensor providing high measurement accuracy and excellent long-term stability.

Key Benefits

Excellent long-term stability through technology
The PTB330 offers high measurement accuracy and superior stability thanks to the Vaisala BAROCAP® Sensor. These barometers operate over a wide temperature range and perform reliably even in highly demanding applications such as professional meteorology and aviation.
Low hysteresis, high repeatability
Combining two powerful technologies – single-crystal silicon material and capacitive measurement – BAROCAP® sensors feature low hysteresis and high repeatability.
Reliability through redundancy
When two or three sensors are used, the barometer continuously compares the readings of the pressure sensors against one another and provides information on whether these are within the set internal difference criteria.
