StepGARD®
StepGARD® is a pressure sensitive detection system that can be employed wherever reliable access control is a necessity – far example for the surveillance of motorway rest areas, container yards, raw material stores, logistics centres and driveways. StepGARD® is the ideal anti-theft sensor for use in outdoor areas, as it is both invisible and undetectable.
The threshold of the pressure sensitive system adjusts itself dynamically to the surrounding conditions. The evaluation module generates a switching signal according to changes detected in the waveguide's optical characteristics when a load is applied. By making the appropriate parameter selections, it is possible to detect changes in transverse pressure of between a few kilograms and several tonnes. A number of different multimode glass core fibres may be employed, depending on requirements.
As no metal components are used, the StepGARD® sensor system remains invisible to metal detectors and magnetic field probes.
Properties
StepGARD® adapts itself dynamically to the surroundings and is able to identify gradually rising loads, such as snowfall. This prevents the occurrence of false alarms.
Thanks to its extreme sensitivity, the detection system can be employed beneath virtually any surface, with the exception of prestressed concrete. StepGARD® operates reliably and unproblematically even when installed under turf, paving, soil, concrete slabs and gravel.
The most important parameters of StepGARD®:
- Glass optical waveguide with a core diameter of 50μm
- Operating temperature range of the optical waveguide: -40 °C to +85 °C
- Joint systems with IP67 safety rating
