VOltage reference doubt.

  1. Sep 5, 2011 #1
    I have sensor that produces differential output. I saw in the sensor schematic that they have used 2.5v DC as reference in the output minus terminal. I am taking sensor output as differential that both positive and negative(2.5DC ref terminal)in count. I got output as 1v of DC when the sensor is placed near to my setup(pump with Accelerometer sensor)

    My doubts are..
    1) What happened to 2.5 reff voltage. Why i get as 1v in output.
    2) why we used these reference voltage.

    Please clear my doubts.
