ABSTRACT:
An armature position monitor for determining the position of an armature within a solenoid and any device controlled thereby. By way of example, the monitor is useful to indicate the position of a solenoid controlled valve such as a sub-surface safety cutoff valve by detecting and utilizing a signal generated in a solenoid actuator for the armature upon the movement thereof toward or away from its extended position to control the power supplied to the solenoid.
