Calculate Control Valve Stem Position
An electronic loop controller outputs a signal of 8.55 mA to a direct-responding control valve (where 4 mA is shut and
An electronic loop controller outputs a signal of 8.55 mA to a direct-responding control valve (where 4 mA is shut and
A 4 to 20 mA current signal represents a 0 to 100 percent scale. Usually, this scale is linear, as
This is used to convert the standard current signal in the range of 4-20 ma to the percentage value 0
