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.
Claims19
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, wherein the current profile includes at least a first data field associated with the magnitude of the current and a second data field associated with the state of the valve, using the current profile to potentially alter a state of the driver;
- and
- an analysis module for using the current profile and the state of the valve to perform at least one action, wherein the at least one action includes generating the current profile associated with the valve.
