Systems and Methods for Detecting Lever Locking Positions on Liquid Level Controllers

摘要

During shipment or other handling events, it is necessary to protect a liquid level controller from damage by manually engaging a lever locking mechanism to secure a lever assembly of the liquid level controller. The lever locking mechanism must be manually disengaged prior to calibrating or putting the liquid level controller into operation. To better facilitate an operator in monitoring the state of the lever locking mechanism, a sensor is coupled to the lever locking mechanism to detect whether the lever locking mechanism is in a locked or unlocked position. This information is then provided to the operator via a user interface. Compared to current visual inspections, the use of the sensor is more robust and reliable, and provides a simple non-contact method for determining the state of the lever locking mechanism.

主权项

1. A computer-implemented method for detecting lever locking positions on a liquid level controller, the method comprising:
detecting, by one or more processors, presence of a magnetic field produced by a feedback element of a sensor, the presence of the magnetic field being detected using a sensing element of the sensor and the sensor being coupled to a lever locking mechanism of the liquid level controller; determining, by one or more processors, that the lever locking mechanism is in a locked position if the presence of the magnetic field is detected; determining, by one or more processors, that the lever locking mechanism is in an unlocked position if the presence of the magnetic field is not detected; and providing, by one or more processors, the determined locked or unlocked position of the lever locking mechanism to a user.
