How to detect Cylinder not moving?

[nickchow]

Cylinder is Compress Air driven. Now my Customer want to konw if there is any other method to detect the Cylinder is not moving to end Stroke other than using End Reed Switch as Detection. Air from Solenoid Valve is control at 1~2Bar to Air Cylinder. Is there anything that can be fix between Solenoid Valve and Cylinder to detect that the Cylinder is jam in the middle?

Thanks in advance.

You might consider an electronic tachometer. There are several styles available and can convert an rpm to 4-20 mA signal.

Give Festo a ring, or some one in the same a trade.

You can put a microswitch at the end if physical motion rather then a reed switch. I do not know of any way to do this at the solenoid.

thks to all. i chked with few vendors couple of months back. They don't have such product. I will check with them again this time, maybe they have something new.

We done something using Sensor but that was a Rodless Cylinder which is much easier. This time, this is a Rod Cylinder.

Probably using a Flow Meter can work but Flow Meter is pretty ex ;>

Along these lines, just consider a flow switch.
