INTELLIGENT ACTUATOR AND METHOD OF MONITORING ACTUATOR HEALTH AND INTEGRITY

摘要

An intelligent actuator for a control valve includes an actuator body, an actuator rod, a biasing device, a controller, and at least one sensor. The actuator body includes an actuator casing defining a cavity. The actuator rod is adapted to be coupled to a control element of a control valve. The biasing device is disposed in the cavity of the actuator housing and operably coupled to the actuator rod for biasing the actuator rod into a predetermined position. The controller is carried by the actuator body and includes a memory, a processor, and logic stored on the memory. The at least one sensor is operably coupled to the controller for measuring various parameters of the actuator and transmitting those parameters to the controller. The at least one sensor can include one or more vibration sensors, one or more acoustic sensors, one or more temperature sensors, etc.
