FIELD: measuring equipment.
SUBSTANCE: invention relates to the measurement equipment. Essence of the invention consists in that the accelerometer for measuring linear accelerations further comprises an integrating device and a controller which performs the function of generating at its output a control signal with a period which is a multiple of the whole number of periods of the alternating sign signal of the reference frequency, wherein the second output of the alternating sign signal generator of the reference frequency is connected to the input of the controller, one of the inputs of the integrating device is connected to the output of the charge amplifier, and the second – to the output of the controller, and the output of the integrating device is the information output of the accelerometer.
EFFECT: high accuracy of measuring linear accelerations when measuring them using a piezoelectric exciter.
