Abstract
A device is configured to monitor a state of a rotatable handle of a valve when the device is attached to the rotatable handle. The device comprises a vector magnetometer configured to measure a magnetic field. The device comprises a processing unit configured to obtain from the vector magnetometer measurements of the magnetic field when the handle is rotated; calculate a change in the state of the rotatable handle based on a difference between the measurements of the magnetic field; and report the change in the state.
Claims14
A device configured to monitor a state of a rotatable handle of a valve when the device is attached to the rotatable handle, the device comprising a vector magnetometer configured to measure a magnetic field;
- the device further comprising a processing unit configured to:
- obtain from the vector magnetometer measurements of the magnetic field when the handle is rotated;
- calculate a change in the state of the rotatable handle based on a difference between the measurements of the magnetic field;
- and
- report the change in the state.
A valve comprising:
- a rotatable hand;
- and
- a device configured to monitor a state of the rotatable handle,
- wherein the device includes a vector magnetometer configured to measure a magnetic field, and
- wherein the device further includes a processing unit configured to
- obtain from the vector magnetometer measurements of the magnetic field when the handle is rotated;
- calculate a change in the state of the rotatable handle based on a difference between the measurements of the magnetic field;
- and
- report the change in the state.
A method for monitoring a state of a rotatable handle of a valve, the method comprising the steps of:
- obtaining from a device attached to the rotatable handle comprising a vector magnetometer measurements of a magnetic field when the handle is rotated;
- calculating a change in the state of the rotatable handle based on a difference between the measurements of the magnetic field;
- and
- reporting the change in the state.
