Three harsh environments. One tough sensor

Cold Storage
From banana rooms to ice cream storage to food processing facilities, your cold storage areas are subject to extremely low temperatures — plus changes in humidity during cleaning and changes in pressure due to opening and closing doors. These fluctuations can cause some ammonia sensors to go into fault or false alarm. But since workers are often present in these areas, it’s critical for ammonia sensors to stand up to tough conditions and accurately report gas at low levels.

Refrigerated Processing Areas
Some of the harshest environments in the food industry are spiral freezers and blast freezers, where rapid freezing often means drastic changes in temperature. This temperature shock — along with humidity shock from hot-water washdowns — can further challenge the resilience of your ammonia sensors.

Engine Rooms
Finally, the most likely places for a catastrophic ammonia leak are often your engine rooms, since they typically hold ammonia for use throughout your plant. But in the hot conditions of most engine rooms, the liquid electrolytes in standard ammonia sensor cells can dry out quickly, sometimes reducing the sensor’s life span and causing false alarms.
