#101232 - You can sense the stops by measuring the Responding to: ???'s previous message |
You can sense the stops by measuring the current to the motor (and be fast enough that it does not burn). I have seen such schemes, half of which failed when some environmemtal condition (temperature, dust, dirt etc) changed.
I do not know your application, but im most cases I would not trust anything but a microswitch to tell me the valve was closed. Erik |
