- Barometric pressure sensors measure fluctuations in the pressure exerted by the atmosphere.
- The sensors require protection from condensing humidity, precipitation, and water ingress.
- They are typically housed with the data logger inside an environmental enclosure.
- If the enclosure is airtight, the sensor's pressure port must be vented to the atmosphere.
- Optimized to mount in Campbell Scientific enclosures
- Low power consumption
- 500 to 1100 hPa (mBar) and 800 to 1100 hPa (mBar) versions also available by special order—contact Campbell Scientific
- Integral switching circuit limits power consumption to measurement cycle
