Abstract:
A medical fluid machine having a solenoid control system with temperature compensation includes an electromechanical solenoid 20 including an armature 24 and a coil 22, a voltage source, a switching device 18 configured to selectively apply power from the voltage source 12 to the solenoid coil, and a control element 30 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.
