Speed into ball-bearings

This particular application on bearings is designed to measure the speed of balls or rollers. In this case, the detection method implemented with OPTEL-TEXYS sensors is of the "through-beam" type.
Optical sensors called FFO are installed face to face with transmission on one side of the bearing and reception on the other. Thus, it is the alternating passage of the balls that will interrupt the beam and generate the speed frequency signal. This signal can be in the standard TTL format or in analogue form as proposed on the 152M sensor. The analysis of this analogue signal can lead to a more detailed understanding of the phenomena.
