Schmeissner: capacitive field change detector Cx 1
The Cx-1 capacitive field change detector is a sensor for monitoring objects and areas for approach and contact. It is based on the measurement of changes in an electric field and can be used regardless of the material properties or shape of the monitored object. A key area of application for the detector is the monitoring of safes. In contrast to conventional detectors, which often consist of several sensors and react sensitively to vibrations, the Cx-1 recognises approach and contact regardless of disturbing influences such as vibrations caused by traffic or construction work. It is installed via a conductive connection on the outside of the safe. It is possible to monitor several safes with just one detector. Another field of application is the protection of works of art in museums.
The detector creates an invisible protective barrier around exhibits and detects unauthorised approaches or tampering. The sensors can be integrated in walls, display cases or directly on objects. The Cx-1 is also suitable for monitoring surfaces and walls. In safety-critical areas, the technology can be used to detect breakthrough attempts. This method is unaffected by mechanical shocks and reduces the risk of false alarms.
The Cx-1 can also be used to secure grilles, for example in ventilation shafts or windows. It registers manipulations such as the bending or severing of struts. Special signal processing ensures that weather influences or contact from outside do not trigger any unwanted alarms. Latch detectors based on capacitive technology enable unobtrusive access control to certain areas. Sensor surfaces in the floor generate an electric field that is disturbed when stepped on. This is particularly suitable for discreet monitoring solutions, for example in museums or security areas. Thanks to its technical features and VdS-C certification, the Cx-1 is suitable for a wide range of security applications.
