Benefits
- High accuracy characteristics over the entire operating temperature range up to 0.08% over the entire pressure measurement range, including the initial section
- High resolution
- High resistance to external factors impact
- Domestic element base
Scope
Systems of surface ships and underwater vehicles.
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.
Measuring Instruments Type Approval Certificate RU.С.30.018.В No. 59270.
