摘要： A coil arrangement comprises an electrical coil and an armature movable between a first end position (I) and a second end position, an electronic switch switchable between at least two switch states, a control and monitoring circuit for producing a switching signal actuating the electronic switch and an operating circuit for providing an operating voltage and an electrical current measurement signal representing an electrical current flowing as a function of time in a coil electrical current circuit formed with the coil. The control and monitoring circuit is additionally adapted using the electrical current measurement signal to perform a checking of the coil, for example, namely to detect, whether an inductance, of the coil has a dependence on the switching signal as a function of time, respectively a behavior as a function of time corresponding with the switching signal as a function of time. The electromechanical switch, in turn, comprises a first switch contact movable between a first switch position and a second switch position, a second switch contact and, for actuating the switch contact, a coil arrangement of the invention, while the measurement transmitter comprises, besides such an electromechanical switch, also a measuring circuit for receiving at least one transducer signal dependent on a physical or chemical, measured variable and/or representing the measured variable as a function of time.
