what kind of sensor do you suggest? wouldn't a wire connected to the edge of the blade be better? (if the blade breaks, the wire would be cut off, and hence we have an open circuit)
Some parameter proportional to the LENGTH and/or CROSS-SECTIONAL area of the metal blade should be observed to reach a certain value at fracture/break down.
Dear all,
The idea is to detect break down of a group of blades inside a pipe. It’s very difficult to install any type of sensors inside a pipe without having them damaged, given that the pipe is an air vacuum suction system.
How about concentrating on the physical properties of the blade...
