CONTROL DEVICE WITH ACCELEROMETER FOR FEEDBACK ON POSITION Russian patent published in 2019 - IPC G01D5/12 

FIELD: machine building.

SUBSTANCE: present invention generally relates to process control devices, such as valves, and particularly to methods, systems and devices for providing feedback on the position of process control devices in a process control system. Disclosed is a wireless sensor or a position converter with an accelerometer, which is physically connected to a control device in a process control system and comprises an accelerometer which generates a signal based on the position of the control device or its actuator. Converter converts accelerometer signal into radio signal, which includes value indicating actuator position, and transmits radio feedback signal by position along wireless channel to valve controller, for example, using short-range wireless protocol. Controller controls the valve based on the value included in the radio signal. In some configurations, feedback signal is received to device conjugated with converter, and conjugated device sends feedback signal to controller.

EFFECT: conjugated device can be interfaced with multiple converters and/or sensors and can transmit different feedback signals to multiple receiving controllers and other devices.
