Abstract

The device for visualising the change of state of a system (1) includes a passive oscillating circuit (2), solidly attached to the system, which is tuned to a specific frequency. The circuit is capable of being connected in a short circuit by a switch (7) which is activated at the moment when the monitored system changes state. The passive circuit is intended to put into resonance by a detection device, external to the system or the passive circuit. The detection device may be tuned to the frequency at which the passive circuit has its resonant frequency. Thus from an external source, the state of the passive circuit and hence the state of the monitored system may be detected.
