An ice machine with a vertical cube evaporator sensor will switch from refrigeration cycle to harvest cycle by using which sensor?

The switching from the refrigeration cycle to the harvest cycle in an ice machine is determined by the ice thickness sensor. This sensor specifically measures the thickness of the ice that has formed on the evaporator plates. When the ice reaches a predetermined thickness, the ice thickness sensor signals the control system to switch from the refrigeration phase, where the ice is being produced, to the harvest phase, during which the ice is released from the evaporator.

This process is crucial for efficient ice production and harvesting. An adequately functioning ice thickness sensor ensures that the ice is produced to the desired thickness before it is harvested, optimizing both the quality and quantity of ice produced while preventing issues such as ice jams or insufficient ice formation.

In contrast, while other sensors like temperature sensors, pressure sensors, and flow sensors play critical roles in overall system monitoring and efficiency, they do not directly influence the transition between refrigeration and harvest cycles as effectively as the ice thickness sensor does. This specialization of the ice thickness sensor makes it the correct choice for this particular operational transition in the ice machine.
