Calculate Current (4-20ma) from Process variable PV
Calculate ma from pv

Calculate current from Process variable: This tool is used to calculate the current signal in the range of 4-20ma using process variable (PV), Upper Range Value (URV) & Lower Range Value (LRV).

.
This calculation tool is used to find out the equivalent current signal 4-20 ma using PV,URV & LRV.


Where,
             PV    =  Process Variable
             URV =  Upper Range Value  (Transmitter Max scale value)
             LRV =   Lower Range Value (Transmitter Min scale value)
Note:
1.For calculating the equivalent current 4-20ma, we have to enter PV, URV & LRV details.
1.The above calculation tool designed for a standard 4-20 ma signal conversion.
2.You can convert out of range signal also with the above tool.
   (Example: URV = 100, LRV = 0 and PV = 110)
