FIELD: geophysical instrumentation engineering; recording variations in atmospheric pressure; study of high-vacuum plants, artificial disturbance of atmosphere and geophysical exploration of gas and oil fields.
SUBSTANCE: proposed device has barometric sensor provided with frame and brace on which rocker arm is turnably mounted; secured on said rocker arm are hollow ball, measuring spring and counter-weight. Besides that, proposed device is provided with temperature compensator consisting of two pairs of magnets, compensating spring and two additional springs and control and calibration unit.
EFFECT: enhanced accuracy of measurement and angular sensitivity of barometric sensor; enhanced accuracy of calibration against primary standard.
