The Vaisala Digital Barometer PTB330 is designed to capture accurate barometric pressure readings under the harshest of conditions.
Built around Vaisala’s trademarked BAROCAP® sensor technology, the PTB330 combines absolute pressure measurement and exceptional accuracy with low hysteresis and long-term stability.
Sensor redundancy supports critical and demanding applications where accurate results are a must.
Advanced sensor technology that leverages single-crystal silicon material and capacitive structure to deliver absolute pressure measurement with low hysteresis, high repeatability.
Intuitive menu-based interface for easy customization of unit display around your specific informational demands.
Multilingual display allows data viewing in English, German, French, Spanish, Swedish, Finnish, Japanese, or Russian.
Graphical display with six different time windows lets you compare and review weather trends using historical data as far back as one year.
Wired or battery power with voltage supply ranges from 10 to 35 VDC, allowing for use in battery-powered applications. An external AC supply enables connection to all universal main AC supplies.
Two alternative accuracy classes, including Class A accuracy for the most demanding applications such as barometric reference, and Class B accuracy for more conventional use.
