g The invention relates to a measurement technique and can be used to simultaneously measure linear and angular accelerations.

The purpose of the invention is to enhance the functionality of the measuring transducer by simultaneously measuring linear vibrations and angular acceleration.

The drawing shows schematically the proposed device.

In the housing 1 there are two chambers 2 and 3 connected by two channels 4 and 5. The internal volume of the chambers and the channels are filled with working fluid, for example electrolyte 6. The chambers are limited on the front sides by membranes 7 and 8. The systems of electrodes 9 and 10 are located respectively in channel 4 and 5 and together with the electrode 6, form electrolyte flow converters into an electrical signal.

Channels 4 to 5 are located diametrically at a distance R from the axis of sensitivity O passing through the centers of chambers 2 and 3. The current leads 11 and I2 from the electrode systems are connected to an electric circuit 13 for converting and reading an electric signal, for example, two differential resistive chains with electric signal removal by voltage.

The device works as follows.

In the presence of linear acceleration along the axis of sensitivity O, the electrolyte 6 of the converter,. which is simultaneously inertial mass, moves along measuring channels 4 and 5 along electrodes 9 and 10 as the body turns, the liquid flows through the channels in different directions. The sum and difference of the output electrical signals from electrodes 9 and 10 are proportional to the linear and angular accelerations, respectively. I Il. -.

Mr. direction. On the electrodes 9 and 10, electrical output signals are formed, the sum of which is proportional to the linear acceleration. When rotated with acceleration of the body in the plane of the contour formed by channels 5 and 4 and chambers 2 and 3, the electrolyte flows through electrodes 9 and 10 and has a different direction, and the difference between the output electrical signals from the electrode is proportional to the angular acceleration.

Thus, the proposed device, due to the execution of two measuring channels spaced apart from each other with readout electrodes placed in each of them, allows simultaneous measurement of linear and angular accelerations. The separation of the output signals is carried out by a readout circuit of the sum and difference of the signals.
