Abstract
One implementation is a device for determining the position of a valve. The device uses a current profile including at least the magnitude of current, and an analysis module for using the current profile and the state of the valve to perform at least one action.
Claims20
A device for determining the position of a valve comprising:
- a driver having a mechanical connection to the valve and configured to change a position of the valve;
- a controller electrically connected to the driver and configured to electrically cause the driver to change the position of the valve;
- a current sensor electrically connected to the driver configured to detect a magnitude of current associated with the driver;
- a position switch associated with the valve configured to detect a state of the valve;
- a current profile including at least the magnitude of current;
- and
- an analysis module for using the current profile and the state of the valve to perform at least one action.
4 more elements
One or more hardware-based non-transitory memory devices storing computer-readable instructions which, when executed by the one or more processors disposed in a computing device, cause the computing device to:
- change a position of a valve using a driver having a mechanical connection to the valve;
- detect a magnitude of a current associated with the driver using a current sensor electrically connected to the driver;
- detect a state of the valve using a position switch associated with the valve;
- and
- perform at least one action with an analysis module that uses at least the magnitude of the current and the state of the valve.
