FIELD: technology for measuring parameters of impulse mechanical loads, possible use for continuous registration of profiles of movement speed of substance under extreme conditions.
SUBSTANCE: capacitive sensor contains measuring flat capacitor, filled with layer of air, with immobile or mobile electrodes, measuring line and power circuit. One of piezo-element electrodes is used as immobile electrode of measuring capacitor. Capacity of piezo-element is selected to be significantly greater than capacity of measuring capacitor. Measuring line is made input form of optical channel for measuring movement parameters of piezo-element surface.
EFFECT: increased interference resistance of sensor from electromagnetic pickups, expanded functional capabilities and area of possible use.
