Answer Posted / lomesh vadhankar
For 4-20mA, the linearity scale comes proper, as well as if
we want to convert, 4-20 mA than its easy to factorize, in
range of, 0-25%,25-50%,50-75% and 75-100%.. So, If suppose,
any control valve is needed to control, then it will be
easier to control it... And for other reasons, as
Mr.S.I.Saravanamurthy Perfectly said, is the ZERo zone. so
that, the Dead condition of any instrument can be
differentiated from normal Zero parameter condition.
Thank you..
