摘要： On a first part (co) of the casing there is an armature (ar), in which a wheel (wh) is fastened in a rotating way, said wheel rolling along a second part (wa) of the casing when the casing is being opened. The wheel is provided with a brake (b) having different braking torques when the wheel rotates in one or another direction and is linked via a shaft (sh) in its axis of rotation with a panel of a trimmer capacitor, said panel being rotatable for an unlimited angle. The capacitor defines the common capacity in an oscillating circle, with which the casing is equipped. The occurrence of a relative change (fn+1 - fn)/fn of the frequency of the oscillating circle between two consecutive checkings of frequency not equalling zero is preferably automatically reported to a supervisory location.
In order to detect any opening even in the absence of a supply voltage, the casing of the invention is adapted with standard components in a simple and reliable way.
