counter

hydraulicmic

I am manufacturing a hydraulic circuit that extends and retracts a hydraulic cylinder continuously. I want to add a digital counter which will count up to 1000. The hydraulic cylinder is operated by a 24v dc solenoid valve which I assume can be used to signal the counter. as I have little knowledge of electronics , can someone please recommend a suitable counter and explain how to connect same please.

    Hi ,

    There are many ways to do this and without details on your application it is only possible to respond in a general way.  For example, it is possible to sense cylinder movement or electrical changes.  The electrical change could be detected with a current sensor or more directly voltage.  Assuming voltage and a simple microcontroller like an Arduino the 24V could be reduced to an acceptable range with a voltage divider made with resistors and measured directly with output sent to a display which would require some programming.  There are also commercial products - do a search for "totalizing counter" - that can do electric or mechanical counting.  If you give more detail someone may be able to give better advice.

    Maybe a really cheap step counter (pedometer) would work.

    Do you need this counter to turn the machine off after 1000 cycles?

    You can buy digital counter relays that might do the job.
