A method of operating a solenoid valve can include applying power to a coil of the solenoid valve, interrupting power to the coil upon a first increase in power consumption of the coil, detecting a first on-time when power is applied to the coil, re-applying power to the coil upon a first condition becoming satisfied, interrupting power to the coil upon a second increase in power consumption of the coil, detecting a second on-time when power is re-applied to the coil, comparing the first on-time with the second on-time, and detecting when an armature of the solenoid valve has physically shifted based at least in part on the comparing. Detecting when the armature of the solenoid valve has physically shifted can include determining that the second on-time is greater than the first on-time.

Assuring dropout of solenoid valve controlled by peak-and-hold driver
Systems and methods of controlling a solenoid coil in a solenoid valve provide a controller that allows a supervisory or leakage current to be used in a peak-and-hold driver. The controller introduces a delay time after detection of a dropout voltage that prevents the solenoid coil from being immediately re-energized in order to ensure proper dropout of the solenoid coil. The delay time imposes a wait period during which the controller takes no action with respect to the current in the solenoid coil, allowing the solenoid coil to deenergize and return the valve to its normally-open or normally-closed position. Such use of a delay time may be limited to instances where the controller has already gone through a power-up cycle such that the response time needed by the controller to energize the solenoid coil is minimized, thus reducing the valve startup time.

A solenoid coil assembly for hazardous environments comprises a solenoid coil and an enclosure entirely filled with encapsulation material. The encapsulation material leaves zero or almost zero volume in the enclosure for hazardous material to accumulate in any amount that could explode. This allows the solenoid coil assembly to be constructed without the usual industry standard flame paths. Additionally, the enclosure may be made of physically rigid and strong material such as metal or the like to better withstand harsh and corrosive conditions within hazardous environments without being explosion proof. The walls of such an enclosure need only have a moderate thickness and weight relative to enclosures that are explosion proof, as there is no meaningful risk of an explosion occurring within the enclosure. The combination of a rugged exterior and a zero-volume interior allows the solenoid coil assembly to reduce weight and cost while providing superior environmental protection.

A solenoid coil assembly for hazardous environments comprises a solenoid coil and an enclosure entirely filled with encapsulation material. The encapsulation material leaves zero or almost zero volume in the enclosure for hazardous material to accumulate in any amount that could explode. This allows the solenoid coil assembly to be constructed without the usual industry standard flame paths. Additionally, the enclosure may be made of physically rigid and strong material such as metal or the like to better withstand harsh and corrosive conditions within hazardous environments without being explosion proof. The walls of such an enclosure need only have a moderate thickness and weight relative to enclosures that are explosion proof, as there is no meaningful risk of an explosion occurring within the enclosure. The combination of a rugged exterior and a zero-volume interior allows the solenoid coil assembly to reduce weight and cost while providing superior environmental protection.

The present disclosure provides a method and system for measuring increase in wattage to detect a potential winding failure. The increase in watts in the winding occurs when a time-varying magnetic field from active turns of the winding induces a time-varying current on shorted turns of the winding. The resistance through the shorted turns and the induced current result in power usage and increased watts. The wattage increase is much greater than a resistance decrease in the winding by the shorted turns. Measuring the watts results in detecting a shorting winding with greater sensitivity than measuring the resistance. In one embodiment, the winding can be tested offline with a wattmeter and power supply. In another embodiment, the winding in use and its wattage can be monitored continuously or periodically locally or remotely, with an optional sensor to initiate a signal upon reaching a certain percentage increase in watts.
