Poultry, Meat, Fish Processing

Many types of environments must be considered when choosing gas sensors for a processing plant. Temperatures may range from ambient levels of the engine room to -40°F or colder in blast or spiral freezers. Meat, poultry, or fish processing requires extensive washdown, a major factor in choosing sensor technology and a sensor manufacturer who understands the environmental factors. Manning Systems sensors will operate in 100% RH (condensing) conditions and throughout a wide temperature range.

A diffusion-type system has great advantages in cold or wet meat, poultry, and fish processing environments. There is no danger of pumping water back to a central analyzer or the possibility of diluting the ammonia sample, as would be typical of a sample draw system installed in a wet environment. Ice formation in the sample draw tubing can block the return lines and totally disable the system.

Manning Systems sensors are housed to withstand washdown, and cleaning chemicals will not cause false trips with electrochemical sensors, even for trip levels as low as 15/20 ppm ammonia.

Manning Systems enclosures with optional ATMOS equipped^® technology (Adaptive Temperature and Moisture Optimizing System) feature the first enviro-adaptive technology available for gas sensors. Manning Systems electrochemical and infrared gas sensors with ATMOS equipped^® technology can automatically adapt to environments from -50°F to 100% humidity and washdown conditions, assuring industry leading performance in the harshest environments.

If electrical shutdown is to be triggered by high ammonia levels, the IR-NH₃ infrared sensor is specific to ammonia in the 1%-2% range and will operate without false trips in all areas of processing or food storage.

In recent years consideration is being given to monitoring other gases besides ammonia in process plants. These include chlorine, chlorine dioxide, oxygen, hydrogen (in battery charging areas), methane (in boiler rooms), etc. The GM-10 or GM-4 will monitor any combination of gas sensors to provide a "total gas monitoring safety system" for an entire facility.
