Pressure method The default pressure port is φ8 gas mouth, in which the long nozzle is the high-end pressure port and the short nozzle is the low-end pressure port. (Φ6 gas mouth or quick connector can also be used) Zero and Full Scale Adjustment There are two types of wind differential pressure transmitter with potentiometer and without potentiometer. If the user chooses the potentiometer hole (the user can manually adjust the zero position. Note: If there is no standard pressure source, do not move the full-scale potentiometer, otherwise it will affect the accuracy of the transducer), uses...
