ABSTRACT:
A medical fluid machine having a solenoid control system with temperature compensation includes an electromechanical solenoid including an armature and a coil, a voltage source, a switching device configured to selectively apply power from the voltage source to the solenoid coil, and a control element connected electrically to the switching device and operable to receive at least one signal indicative of a resistance of the coil and using the signal to control the switching device to selectively apply power from the voltage source to the solenoid coil.
