Microphonic Cable Technology

Flexmic

FLEXMIC is a detection system for structure-borne noise, based on a piezoelectric microphonic cable. The sensor cable’s operating principle guarantees both high sensitivity and a wide frequency spectrum, and the compact design and integrated logic functions make this system of interest for industrial applications. The system is particularly suitable for monitoring flexible and rigid mesh fencing, and metal grid fences.

Applications:

Monitoring of wire mesh fences and other lightweight fences, and any structure able to carry structure-borne noise.

Operation:
Microphone cables are laid on the fence along the track to be monitored.
The sensor cable is usually attached to the fence using weather-resistant cable ties or is concealed within the construction. For some fence panels special installation kits are available for concealed cable installation. The cable absorbs material vibrations (structure-borne noise), the downstream evaluation unit then evaluates the sensor signals and reports attempts to break in or out.
The evaluation units can be operated both as individual electronics and as part of a networked system. The electronics offer the option of real-time local signal correlation to minimize unwanted signals resulting from environmental influences.
This function is extended by installation-wide correlation where evaluation units are networked.
Up to 64 FLEX units can be networked to a central hub (e.g. MASTERCENTRAL) via various interfaces. Alongside the data interfaces a wide range of IO modules exist, through which further information can be captured and put out.
