ABSTRACT:
A refrigeration case monitoring system. In one embodiment, the refrigeration case monitoring system includes a first fiber optic cable, a second fiber optic cable, and a control system having a first sensing channel and a second sensing channel. The first fiber optic cable transmits a signal that is indicative of a refrigeration case condition. The second fiber optic cable transmits a signal that is indicative of a second refrigeration case condition. The control system receives the signals from the first and second fiber optic cables using the first and second sensing channels, processes the signals, and provides an output related to the first and second refrigeration case conditions.
