• The precision probe heads and the sensor shaft are made of metal. • The flow velocity is recorded with high accuracy. • Every vane anemometer is adjusted individually. The multipoint adjustment is saved within the ALMEMO® D6 plug. • Measurement operations carried out by a vane anemometer in air/gas are in practice nearly completely unaffected by environmental variables such as pressure, temperature, or humidity. The low dependence of the measured value on Nominal conditions 22 °C ±2 K, 1013 mbar Connection cable permanently connected cable, FEP/silicone shielded, 2 meters, with Lemo plug ALMEMO® adapter cable Lemo coupling cable, 0.2 meters, with ALMEMO® D6 plug Frequency measurement resolution 0.01 Hz Multi-point adjustment sensor specific, saved within the ALMEMO® D6 plug of the adapter cable density can be compensated. The density of the gas can be programmed within the ALMEMO® D6 sensor menu on the ALMEMO® V7 device. • The rugged construction is suitable for mobile as well as for stationary measurement operations. • The ALMEMO® D6 plug measures the frequency signal of the vane with high resolution. • One measuring channel is programmed (at our factory): flow velocity v (m/s). Refresh rate 0.5 seconds for all channels Averaging period 2 seconds, programmable from 2 to 100 s Supply voltage 6 to 13 VDC For more information about general features of the ALMEMO® D6 sensors, see chapter ALMEMO® Measuring instruments 11/2025 • We reserve the right to make technical changes.
