Discussion Overview

The discussion revolves around methods to detect whether a compressed air-driven cylinder is not moving to its end stroke. Participants explore alternatives to using an end reed switch for detection, considering various sensors and devices that could be implemented between the solenoid valve and the cylinder.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant suggests using an electronic tachometer that can convert rpm to a 4-20 mA signal as a potential detection method.
  • Another participant proposes installing a microswitch at the end of the cylinder to detect physical motion instead of using a reed switch.
  • A participant mentions previous inquiries with vendors regarding detection products, noting that they did not find suitable options but plans to check again.
  • There is a suggestion that a flow meter might work for detection, although it is noted to be expensive.
  • Another participant echoes the idea of using a flow meter and adds that a flow switch could also be considered.

Areas of Agreement / Disagreement

Participants do not reach a consensus on a specific detection method, and multiple competing views regarding potential solutions remain unresolved.

Contextual Notes

Limitations include the lack of specific product recommendations and the uncertainty regarding the effectiveness and cost of suggested methods.

Who May Find This Useful

Individuals involved in pneumatic systems, automation, or those seeking alternatives for motion detection in cylinders may find this discussion relevant.

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.
