DEVICE FOR MEASURING VIBRATION PARAMETERS Russian patent published in 2024 - IPC G01H11/06 G01P15/97 

FIELD: measuring.

SUBSTANCE: device for measuring vibration parameters relates to electrical engineering, namely to measurement of vibration with devices containing a housing. Device comprises terminal connector terminals connected to voltage switch, current switch, which output is connected to voltage switch, and inputs of which are connected to current source and APM controller, analogue filter, the input of which is connected to the voltage commutator, and the output is connected to the analogue-to-digital converter. Said APM controller is connected to an Ethernet controller having a connector with galvanic isolation, with random access memory, a shaper controlled by means of a system reset button, and an RS-485 controller having a connector with galvanic isolation. In addition, the device has terminals for connecting an external current source, which are connected through a noise-suppression filter to a converter for supplying the digital part of the circuit, the output of which is connected to the converter for supplying the analogue part of the circuit.

EFFECT: broader functional capabilities of instruments for measuring vibration parameters, high accuracy of converting analogue signals into digital ones, while ensuring protection of switching of measuring channels under control of the controller from mutual interference.
