Bakeries

Only sensors that are "gas specific" will give satisfactory performance in a bakery. The off-gasing of yeast will cause most sensors to false trip, but the EC provides "no-false-trip" performance for a variety of gases.

Gas-fired ovens produce carbon monoxide and other combustibles. Flavorings, spices, extracts, etc. found in baked goods may off-gas. Flour, always present in a bakery, presents special challenges to the way a sensor is packaged.Washdown and the occasional hose hits can cause problems for gas sensors, unless they are equipped with Manning Systems ATMOS technology.

If any one of these conditions is not addressed in sensor selection, the chances of repeated false trips are greatly increased.

The electrochemical sensors manufactured by Manning Systems are specific to ammonia and will not false trip even at low ppm levels in the presence of other gases typically found in bakeries. In plants using R-22, the AirScan™ iR infrared sensor will monitor refrigerants without nuisance trips.

If very selective high ppm level ammonia monitoring is required, the IR-NH₃ gas leak detector is ideally suited. It will alarm in the 1-2% range without nuisance trips, an extremely important consideration if plant power or compressors may be shut down.
