The AP473 family consists of SICRAM modules for Pitot tubes designed for air speed, differential pressure, calculated flow rate and air temperature measurement in ventilation, HVAC and industrial airflow applications. Four versions are available: AP473 S1, S2, S3 and S4, covering differential pressure ranges up to 10, 20, 50 and 100 mbar respectively, with corresponding air speed ranges from 2 to 40, 55, 90 and 130 m/s. All modules require the Pitot tube to be ordered separately and are designed for use with a K-type thermocouple for air temperature compensation. "PW" (ordered separately) is available as a 2 m connection cable between the module and Pitot tube.
