4. Signal conditioning element basically takes the output of the sensing element and converts it into a form more suitable for further processing, usually in the form of a DC voltage, DC current or variable frequency AC voltage. The output of the sensing element is usually too small to operate an indicator or a recorder. Therefore, it is suitably processed and modified in the signal conditioning element so as to obtain the output in the desired form that is amplify the signal and filtering the unwanted signal. i.
