Airflow sensor/field calibration equipment and manner for non-linear amendment of sender

摘要

(57) Abstract The manner in order to provide the airflow sensor which is calibrated in the VAV system, is linearized and with the device, the factory calibration airflow sensor or the pressure sensor which is adjusted by the transfer function where output was written to the look-up table in each every sensor making use of, it tries amendment the sensor the pickup device/the electronic circuit/the drift/and in regard to turbulence property manner and the device which. It becomes possible to do field adjustment, according to this, with the processor whose throughput is small. In addition, in actual airflow and connection with the influence of the turbulence, furthermore field adjustment is done.
