FIELD: measurement technology.
SUBSTANCE: device can be used for measuring accelerations of objects. Liquid accelerometer has channel filled with working fluid. Two hydrostatic pressure frequency converter detectors are disposed at ends of accelerometer. Frequency converter is made in form of fiber interferometer, which has coherent light source matched optically with two fiber coils and photoreceiver connected with frequency meter through amplifier. To determining sign of acceleration the special electronic circuit is introduced into accelerometer additionally.
EFFECT: optical output signal at output of accelerometer.
