摘要: A device is provided comprising a circuit using the properties of resonating cavity sensor whose resonance frequency modified by electric capacity variations due to mechanical deformation wall under effect pressure be measured. It uses single coaxial cable for connecting user and sensor, through cable, placed in leg an impedance bridge providing value standing wave rate characteristic difference between tuning oscillator controlled this rate.
