The DB-X series is designed for pressure measurements in meteorological stations, aviation, and laboratories. Depending on the technical requirements and the required redundancy, the user can select the specific DB-X model: DB-1 with one, DB-2 with two, or DB-3 with three independent working pressure transducers. The integrated software enables convenient calculation and display of measured pressure values for the specific application, such as QNH, QFE, pressure trend, and historical values.
The barometric pressure sensor used was developed for measurements requiring high accuracy, fast dynamic response, and long-term stability and reliability.All DB-X series barometers are suitable for temperatures from -40°C to +60°C. The sensor and electronic units consume little power during operation.
This type of digital barometer has important advantages:
• Resolution 0.01 hPa, 0.1 hPa or 1 hPa selectable
• Touch display 6 cm x 12 cm for digital pressure display analog trend
• Pressure trend, adjustable between 28 minutes, 2.8 hours and 28 hours
• Long-term stability: better than 0.1 hPa / year
• Measurements without hysteresis
• Instant start: <1 sec
• Low power consumption with additional main supply
• Battery as UPS
• Meets CE conformity standards
• Test pressure 1500 hPa
• Burst pressure 2000 hPa
The standard version with one sensor is an economical barometer for meteorological stations with an accuracy of +/- 0.3 hPa and a resolution of 0.1 hPa.
For requirements requiring higher and highest accuracy with high reliability and redundancy, the user should select the DB-2 or DB-3, each with two or three combined pressure capsules. For aviation use, the touchscreen display shows the values for local pressure, QNH (sea level air pressure), QFE (runway level air pressure) in hPa, and also the TRL (transition level). The resolution is freely selectable with two, one, or no decimal places.
A trend indicator shows the trend of recent pressure values. The user can change the timeline and select in increments. Touching the trend indicator allows you to view pressure values at previous times.
The high accuracy of <0.1 hPa over the entire measuring range is achieved by comparing each sensor at 17 points with a Control Mercury Barometer Type 20k as a pressure standard.
