    Abstract: A flow control that is configured to monitor energy use. These configurations may include a controller that delivers a signal to pressurize a pneumatic actuator. This controller may have software that can calculate energy use based on pressure of the signal and, for example, changes in position of a valve. This feature can provide real-time data that operators can use to identify potential problems on their process lines. In one implementation, the operators can flag devices that exhibit energy use that trends away from baseline levels. These devices may have inherent issues that can manifest into larger, more catastrophic problems, potentially causing quality problems with end product or requiring the operating to shut-down the process line altogether.

    Abstract: A monitor device that is configured for use on flow controls and like industrial devices. The embodiments may include a resonator that is sensitive to vibrations on the flow control. The resonator may generate a non-electrical signal, like pressure waves. This non-electrical signal can transit a conduit to a sensor that can convert the pressure waves into an electrical signal. On valve assemblies, a controller can process the electrical signal to detect potential health or maintenance issues. The controller may, in turn, generate an alert to prompt operators to perform maintenance on the flow control.

    Abstract: A controller for a valve assembly that is configured to meet requirements for use in hazardous areas. These configurations may regulate flow of instrument air to a pneumatic actuator to operate a valve. The controller may comprise enclosures, including a first enclosure and a second enclosure, each having a peripheral wall forming an interior space, and circuitry comprising a barrier circuit disposed in the interior space of one of the enclosures that power limits digital signals that exits that enclosure. In one example, the peripheral wall of enclosures are configured to allow instrument air into the interior space of the first enclosure but to prevent instrument air from the interior space of the second enclosure.
