1. A level sensing system configured for implementation in a process control environment, the level sensing system comprising:
a level detection component configured to rise or fall in response to changes in a level of liquid in which the level detection component is placed;
a member that is mechanically linked to the level detection component such that the member changes position or orientation in response to the level detection component rising or falling;
one or more sensors configured for continuous detection of the level of liquid by way of: (i) continuously measuring the position or orientation of the member, and (ii) generating a detected level value corresponding to the continuously measured position or orientation of the member; and
a circuit communicatively coupled to the one or more sensors and configured to: (i) generate an electromagnetic signal, according to a process control communication standard, to carry the detected level value; and (ii) transmit the electromagnetic signal to a process controller to enable the process controller to implement control in light of the detected level value,
wherein the member includes a lever and an array of magnets disposed on the lever, and wherein the one or more sensors are hall-effect sensors configured to detect the change in the position or orientation of the member by way of detecting one or more magnetic fields from the array of magnets.
