Hello everyone
Please guide in using arduino tachometer to monitor the rpm of a cooling fan inside of a VFD Panel.
Cooling Fan model: D2D160-CE02-11 ABB EBMPAPST .
And relay this rpm data to DCS system.
Provide a link to that fan's datasheet, I couldn't find anything useful on the Net.
That's are super description of the counterpart. It's about as useful as "send the information to a computer". We need a link to the datasheet(/manual of that device that defines exactly what interfaces it has and what physical and logical parameters we can expect.
I would recommend not doing that but use an airflow sensor inplace of that, then you do not modify the blower assembly and void the warranty. I would not expect an Arduino to work properly in a VFD panel because of EMI etc. Take a look at an airflow sensor. You could measure the temperature and air flow, this will let you know if something is failing and / or plugging up. Check this link for starters. F1031V Mass Air Flow Sensor for Arduino Wiki - DFRobot This would be a non invasive solution.
