ABSTRACT:
A dual gain pressure control solenoid having two individually wound coils. One coil has a greater number of turns than the other coil and operates as a high force coil. The coil with a lesser number of turns operates as a low force coil. The low force coil provides improved resolution over a predetermine range of input current, while the high force coil provides less resolution but greater force. The coils may be used in various operational modes in order to achieve improved resolution over a predetermined current range.
