ACCELERATION MEASUREMENT DEVICE Russian patent published in 2010 - IPC G01P15/13 

FIELD: physics.

SUBSTANCE: invention is designed for use as a detecting element in stabilisation and navigation systems and can be used in devices for measuring compensation type mechanical quantities. The device has a detecting element, a position sensor whose output is connected to the input of an amplifier, a magnetoelectric power converter and a second-order broadband filter connected in a negative feedback circuit. The output of the broadband filter is connected to the output of ripple filter, and the output to the input of the magnetoelectric power converter through a voltage-to-current converter. The input of the ripple filter is connected to the output of the position sensor through an alternating current amplifier with a stable coefficient of amplification, a logic element, an XOR circuit and a precision relay element. Outputs of the reference voltage generator are connected to the position sensor and to the XOR circuit through a second logic element and the output of the ripple filter is the analogue output of the acceleration measurement device. Use of the second-order broadband filter with parametres ξ₂ > ξ₁ enables design of a device with a considerable transmission constant on an open circuit.

EFFECT: increased accuracy and wider transmission band.
