• Pressure measuring connector in compact design for flow measurement with Pitot tubes • Fitting for connecting hose between Pitot tube and pressure measuring connector • Pressure measuring connector can be plugged directly onto the measuring instrument. Overload capacity Maximum three times final value Max. common mode pressure 700 mbar Accuracy differential pressure ±0.5 % of final value (zero-point adjusted) in range 0 to positive final value Temperature drift < ±1.5 % of final value Compensated temp. range 0 to +60 °C Hose terminals 0 5 mm, 12 mm long Sensor material aluminum, nylon, silicone, ! On ALMEMO® devices to obtain precise measured results in m/s the wind tunnel temperature can be entered in the -50 to +700 °C range for compensation purposes. 11/2025 • We reserve the right to make technical changes. Advisory note when used in conjunction with ALMEMO® 2890, 5690, 5790, 8590, 8690, 510, 809: The new ALMEMO® pressure measuring connector is very slightly higher (8.8 mm). As a result adjacent input sockets on the ALMEMO® device may be partly covered. However, the 1st input socket can always be used without restriction. Or, alternatively, the ALMEMO® pressure measuring connector can be plugged in at any input socket using connecting cable ZA9060AK1. ALMEMO® pressure measuring connector for barometric pressure 700 to 1100 mbar, without pressure terminal sleeve Technical data see chapter 10 Pressure FDAD12SA including programming for automatic atmospheric pressure compensation (comment *P) OA9000PK (variant with pressure terminal sleeve, see chapter 10 Pressure) Connecting cable, 0.2 meters Extension cable, 2 meters 1 set of silicone hoses black / colorless, 2 meters Silicone hose, black, per meter Silicone hose, colorless, per meter Variants (including manufacturer’s test certificate) Order no. (including one set of silicone hoses, 2 meters) Measuring ranges ±1250 Pa, Differential pressure (1 to 40 m/s), Measured variables m/s, Pa, Measuring connector, independent of position FDA602S1K Measuring ranges ±6800 Pa, Differential pressure (2 to 90 m/s), Measured variables m/s, Pa, Measuring connector, independent of position FDA602S6K DAkkS accredited calibration or factory calibration KV90xx, air flow, and KD90xx, pressure, for sensor or measuring chain (sensor + device), see chapter „Calibration certificates“ DAkkS accredited calibration meets all the requirements regarding test resources laid down in DIN EN ISO/IEC 17025.

Pitot Tubes for Differential Pressure Sensors FDA602 • Prandtl Pitot tubes with hemispheric head. • For measuring the dynamic pressure, the tip of the Pitot tube has an opening of 0.3 d. • For measuring the static pressure, a total of 12 holes with 0.1 d 0 have been arranged at a distance of 3 d. • Pitot tube coefficient 1.0. Accuracy typ. ±0.5 % ! ALMEMO® devices that have an option for entering factors can also be used to perform wind velocity measurements with cylindrical probes, according to VDEH. The cylindrical Pitot tubes have a probe-related coefficient of 1.7. By entering a factor of...
