I need to detect a conveyor belt moving by sensing the rotation of the rollers driving it. The rollers are spinning at 3000rpm, belts speed 20m/sec. The conveyor is transporting coal and has to trigger a water spray system to damp down the coa
I have been thinking about this for a while. Putting a sensor directly on the roller would require the sensor to actuate every 0.02 seconds. This is beyond the limitations of the valves I looked up from Clippard. So I thought of a couple differ
Would you be able to add a ‘dog’ on a roller, that would contact a lever arm to a 3-way valve? If you could, you then could actuate a 3-way valve to give a signal out only when the roller is moving. The valve could have an ‘off-delay’ that would
How about a Fan Blade on one roller with a shroud that points its air flow to an Crouzet or Telemechanique amplifier module that shifts ta under 1 PSI pressure and sends an 20-100 PSI signal to an air operated water valve. No contact but needs som
