    Dear all,

    I am trying to convert the Angle(0-90 deg) into 4-20mA current. Actually the magnet is rotating by the rod. The rod is immersed in the oil. Based on the oil level the rod is rotating. The top of the rod we place the magnet. The rod can be rotatable upto 0-90 degree. So I used Magnetic sensor HMC1512. I have gone through the data sheet.

    When we use the opamp circuit which is given in the datasheet the output wil be linear or it will be the sinusoidal? Because the voltage difference of the wheatstone bridge is mentioned as sinusoidal. And the same circuit is enough or else. Do I need any other amplification circuit and filter circuits?

    Thanks in advance
