1. Product Overview
YGM215 is a  Air speed transmitter specially designed for the measurement of micro  Air speed in the field of laminar ventilation. Based on the principle of Pitot tube flow measurement, the  Air speed measurement is realized by measuring the difference between the total pressure and static pressure of the fluid; The product adopts split design, and the transmission main body and the probe are connected through a silicone tube; The transmission main body provides four standard signals: 0 ～ 10V/4 ～ 20mA/RS485/switching value output mode for users to choose; The probe part is fixed by flange and has a small volume, which is convenient for users to integrate on various types of equipment.
