ABSTRACT:
A coaxial cable pressure sensor having a partially conductive layer of fibres or particles between the inner and outer coaxial conductors whereby pressure applied to the sensor produces a detectable change in resistance of the circuit passing through the partially conductive layer. One or more of the sensors may be incorporated into a vehicle weighing system, preferably in the form of a portable "mat" which may be folded or rolled up.
