how we convert Mili ampere to temp txt,level txt,flow txt,pressure txt range value..

Answer / raja

measurement Milli Ampere - minimum Milli ampere value /
maximum Milli ampere * 100

Example 12mA how mach range tx

12-4 / 16

8/16*100

0.5 * 100

= 50 % RANGE

Answer / faiyaz ahmad

Hai Mr. charan kumar,

Actually the formulae is:

Range= (Actual value(mA)- LRV/Span) * 100%
Span=URV-LRV
=20mA-4mA
=16mA
So,Range=(12-4/16)*100%
=(1/2)*100%
=50%

Answer / abdul rauf

Actual formula is PV (procees variable)-LRV/Span×100%
Range=l2-4/16×16
=50%
And process Varible (ma)=Rang in % ×Span/100+LRV
Ma=50×16/100+4
ma=12
