Cảm biến đo áp suất khí quyển Campbell Scientific BaroVue 10
Overview
The BaroVue™10 is a highly accurate barometer that can measure pressures over a range of 500 to 1100 hPa and can be used in a range of applications that includes meteorology and hydrology. This sensor includes our zero downtime recalibration. Other sensors on the market need to be taken offline and sent back to the manufacturer to be recalibrated, often for weeks at a time, causing a loss in valuable data and time, as well as an additional expense.
The sensor card for the BaroVue 10 is pre-calibrated. Replacement sensor cards are also pre-calibrated, requiring only one trip to the field station and no downtime. The design of the BaroVue 10 allows you to remove and replace your sensor card quickly and easily without either having to disassemble the equipment in the enclosure or having to send the equipment back to the manufacturer.

Detailed Description
The BaroVue 10 is a low-power, digital barometer (-40 to +60°C) that provides best-in-class accuracy and stability (±0.1 hPa/yr) over the entire pressure and temperature range. It can run continuously and does not require power cycling unlike other products in this category. The digital output is both SDI-12 and RS-232, which reduces noise and measurement uncertainty compared with analog sensors, and makes the BaroVue 10 compatible with all Campbell Scientific SDI-12 devices. Moreover, this barometric pressure sensor can be installed and integrated into many new and existing weather stations. The transducers used in the BaroVue 10 are direct-to-digital sensors, and no reconversion takes place inside the barometer.
