I have a control setup with a photo eye's output controlling a solenoid valve. This system is set up to control the tracking of a wide sanding belt. this belt ossilates from side to side on it's drums (as it is supposed to do). The photo eye is set up so that when the belt ossilates over so that the photo eye cannot "see" it, it activates the solenoid which activates an air cylinder which sends the belt moving the other way. My problem is, this photo eye does not always read real clear and therefore does not send a solid signal to the solenoid and therefore causes the solenoid to "chatter".
Finally, here's my question: Is there a device available that I can install between the photo eye and the solenoid to "smooth out" the signal the photo eye receives?

Thanks
