1. Product Overview
YGM205 is a transmitter capable of measuring high wind speed, with the maximum measuring wind speed of 50m/s. One or several pairs of sample gas acquisition holes are set on the probe rod, which can measure the wind speed at a single point or at multiple points; The probe rod has a certain anti pollution ability and can be used under worse working conditions.
The installation of the transmitter is very simple. The probe rod is fixed at the position of the measured air flow through the flange to obtain a stable signal output.

Installation Instructions
The probe rod shall be installed in the straight section of air duct. Because the wind speed at the elbow of the air duct is uneven, the measurement accuracy will be greatly reduced.
The distance from the windward side of the wind speed probe to the elbow shall be more than 5 times the diameter of the air duct, and the distance from the leeward side to the elbow shall be more than 2 times the diameter of the air duct. If the conditions cannot be met, the installation position shall be taken to ensure that the straight pipe section on the windward side is longer than the straight pipe section on the leeward side.
The probe rod shall be installed at the center of the air duct. The position of the probe rod is marked with+and -. During installation, install the "+" direction on the windward side and the "-" direction on the leeward side. First install the flange to determine the installation direction of the sensor.
