CONTROL DEVICE WITH ACCELEROMETER FOR POSITION FEEDBACK |
摘要 |
An accelerometer wireless position transducer or sensor is physically coupled to a control device in a process control system and includes an accelerometer that generates a signal based on a position of the control device or its actuator. The transducer converts the accelerometer signal into a wireless signal that includes a value indicative of the actuator position, and causes the wireless position feedback signal to be transmitted over a wireless channel to a valve controller, e.g., by using a short-range wireless protocol. The controller controls the valve based on the value included in the wireless signal. In some configurations, the feedback signal is received at a device paired with the transducer, and the paired device transmits the feedback signal to the controller. The paired device may be paired with multiple transducers and/or sensors, and may transmit various feedback signals to multiple recipient controllers and other devices. |
