FIELD: measuring equipment.
SUBSTANCE: essence of invention consists in the fact that in strain-gauge linear accelerometer for return of inertial mass in zero position the circuit of electrodynamic balancing is used, which is controlled by signal from output of strain bridge placed on elastic suspension of inertial mass. At that, the strain bridge is powered from the DC voltage source, and the electrodynamic balancing circuit is implemented by the pulse inductive-capacitance converter of the step-up voltage applied between the two galvanically separated parts of the inertial mass and the two electrically insulated parts of the housing, which with inertial mass form two capacitors due to small gap between body parts and parts of inertial mass.
EFFECT: reduced temperature error of the accelerometer, reduced dimensions of the device.
