Abstract

A solenoid valve having a condition monitoring unit, and a method of condition monitoring this solenoid valve are specified. A core of the solenoid valve can be shifted with respect to a holding coil and a measuring coil. A reading voltage is applied to the measuring coil, and the current intensity of a current flowing through the measuring coil is determined at a first and a second time. The first measuring is performed during a switching-on or switching-off operation of the current flowing through the measuring coil. The second measuring is performed when the current intensity of the current flowing through the measuring coil has reached a stationary condition.
