TAUT WIRE SENSING APPARATUS |
摘要 |
A sensor post has a hollow interior and a semi-rigid surface which flexes in response to an applied force. Sensor bars are mounted to the semi-rigid surface in a cantilevered fashion, and include an intermediate electrically insulated section located inside the interior of the sensor post. The sensor element mounting means is rigidly mounted to a portion of the sensor post which remains essentially stationary during an intrusive event. Sensing elements are made of a flexible semiconductive sensing material, whose resistance increases when the material is stretched, and are mounted so as to straddle an electrically insulated section of the sensor bars. A signal analysis means detects an increase in the resistance of the sensing elements and generates an alarm. A wire guiding device uses a separator bar shaped into a zig-zag configuration which is provided with a series of apertures forming an axial channel, and a locking rod dimensioned for insertion into the axial channel formed in the separator bar, thereby entrapping the taut wires.
