Dynamic detection threshold
1,Product introduction
Clearance monitoring method:
Using some distance measuring methods, measure the distance from the blade to the distance measuring device on the fan nacelle/tower, and calculate the distance between the blade and the tower according to the geometric parameters of the fan
The ranging device is generally laser ranging radar or millimeter wave ranging radar, hereinafter collectively referred to as clearance (monitoring) radar
