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 site
- high resolution
- domestic component base
Scope
- road and airfield weather stations
- meteorological condition monitoring system
- water level measurement system (to compensate for the atmospheric pressure impact)
Principle of Operation
The atmosphere pressure sensor operates 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.
