hello
i am trying to make a hot wire annemometer , i want to build a constant temperature annemometer using PT 1000 wire as sensor. To have temperature compensation i will put 2 such wire of pt 1000 on 2 legs of the Wheatstone bridge .But i am not able to figure out the feedback circuit required for constant temperature method. Can anyone guide me ?
