FIELD: machine building.
SUBSTANCE: invention relates to a system and method for controlling a field device, comprising a valve coupler having a first portion, which is configured to be connected to an actuator rod of an actuator, a second portion, which is made with the possibility of connection to a movable component of a control valve, and one or more sensors measuring one or more parameters, which indicate the health and / or remaining service life of the control valve assembly and / or one or more components of the control valve assembly. In addition, at least one of the sensor devices can generate energy from the control valve assembly and / or the operating environment of the control valve assembly for operating electronic devices.
EFFECT: technical result is the ability to continuously monitor the parameters that contribute to the operability of the field device, with the aim of providing the possibility of diagnosing and predicting the health and / or remaining service life of the field device.
