Loading / Unloading Control Question...
Operating several screw type ammonia compressors that are PLC controlled. The loading/unloading controls are monitoring the position of the sliding valve for the PI controller. Sensors on the sliding valves are not totally accurate or reliable. Wondering if the motor amps could be used instead of the valve position input (if scaled accordingly). Anyone seen this done...or have any other suggestions? Many thanks!
