FIELD: measuring equipment.
SUBSTANCE: invention relates to the field of measuring technology for measuring linear acceleration. Linear acceleration sensor comprises a base, a frame body in which bob weight is placed, connected via elastic suspension with a frame body, a joist resonator connected on one side with a bob weight, and on the other hand with the frame body, a system of excitation and signal remove system consisting of electromagnets of excitation and pickup of oscillation and located on the base. In addition, the sensor is equipped with a background compensation system for pickup signal, consisting of polarized electromagnets located with a gap opposite to each other, one of them and electromagnet of excitation of oscillations are connected in parallel, and the other and electromagnet of oscillation are connected in series.
EFFECT: suppression of the DC component of the pickup signal at frequencies other than resonant, without changing the overall characteristics of the linear acceleration sensor.
