Benefits
- High accuracy characteristics are provided over the entire operating temperature range and the entire pressure measurement range without additional errors, including at the initial segment
- High resolution
- Domestic component base
Scope
- Weather stations of the meteorological condition monitoring system
- Water level measurement system (to compensate for the atmospheric pressure impact)
Principle of Operation
The operating principle of atmosphere pressure sensor is based on variations of a resonant vibration frequency of high-quality quartz resonator, which has long-term calibration curve stability under the barometric pressure impact.The product has been assigned as the measuring instrument type and registration number in the State Register of Measuring Instruments 71288-18.
