Digital thermo-anemometer omnidirectional FVAD 05-TOKx, with ALMEMO® D6 plug, with integrated atmospheric pressure sensor for automatic atmospheric pressure compensation 11/2025 • We reserve the right to make technical changes. Technical data and functions • Omnidirectional sensitive tip with exposed heat ball probe. • Optimized version for measuring low flow velocities in air. • Solid construction of the sensor top, suitable for mobile usage. • Digital thermo-anemometer with integrated A/D converter in the ALMEMO® D6 plug. • Automatic atmospheric pressure compensation of the flow velocities dependent on the atmospheric pressure with digital atmospheric pressure sensor integrated in the ALMEMO® D6 plug. Alternatively manual input of the atmospheric pressure in the ALMEMO® D6 sensor menu. Two measuring channels are preprogrammed on leaving our factory: flow velocity (m/s, v), atmospheric pressure (mbar, AP, p). General features and accessories, ALMEMO® D6 sensors: see chapter ALMEMO® Measuring instruments Accuracy: ± (3 % of measured value + 1 % of final value +2 digits) Nominal conditions: 23 °C ±3 K, 50 % RH, 1013 mbar Temperature compensation: effective in the range 0 to 60 °C Temperature effect: 0.5 % of the measured value/K Output time constant: 0.1 s (selectable in the range of Incident flow: omnidirectional Pressure range: environmental pressure Atmospheric pressure compensation: automatically Probe length: 300 mm including peak Probe cable: 5 meters Current consumption: maximum of 350 mA Power supply unit connection: 0.2 meter cable with connection 3 pin connector for the power supply unit ZB1212NA10 ALMEMO® connection: 2 meter cable with ALMEMO® D6 plug Digital atm. pressure sensor (included in the ALMEMO® D6 plug) Measuring range: 700 to 1100 mbar Refresh rate: 0.1 seconds for both channels Supply voltage: via the ALMEMO® device Measuring range 2.5 m/s.
