Hey smart circuit guys,
I am a mechanical engineering grad student who needs to build a constant current hot-wire anemometer to measure turbulent air flows. Nowadays the commercial equipment one buys is always constant temperature, which uses a Wheatstone bridge and an amplifier in a control loop to increase the current as the flow speed increases. The constant current circuit circuit is more simple.
Does anybody have any suggestions on how to get started?
Thank you...
Will
