properly and requires further attention. A maintenance log

Increasing the Lifespan of Ammonia Sensors
Ammonia sensors have a lifespan of approximately two
years in air. To take full advantage of the operational lifespan of the sensor, it is important to understand how the gas
concentration and the length of time of exposure affect the
sensor. Regular exposure and long-term exposure to very low
levels of ammonia over time will consume (reduce the lifespan) of the sensor. Exposure to very high concentrations of
ammonia can kill the sensor leaving it useless for detection.
Therefore, it is important to use a lower concentration of NH3
gas for bump testing.
Depending on what concentration of NH 3 you are using for
the bump test, the length of time you will be applying the
NH3 should change. In most cases the low alarm setpoint is
either 25 ppm or 35 ppm. To perform a bump test, you will
need a test gas that exceeds this low alarm point. There are
three common concentrations of NH3 gas that are available:
50 ppm, 100 ppm, 300 ppm. For each of these you should
use a different length of time for the exposure of the gas to
the sensor.
Example 1: If the low alarm setpoint for NH3 is 25 ppm and
the bump test gas concentration is 50 ppm, it could take up to
approximately two minutes to trip the low alarm for a sensor
of moderate age.
Example 2: If the low alarm setpoint for NH3 is 25 ppm and
the bump test gas concentration is 300 ppm, it could take
as little as 10 seconds to trip the low alarm for a sensor of
moderate age.
In both cases, your goal is to trip the low alarm, but also
reduce the exposure to the gas. Best practice is to remove the
gas as soon as the alarm trips.

Minimum Recommendations
Bump tests should be done once a month. If a bump test
fails, a full calibration should be done. Otherwise, a full calibration should be done every 6 months. The sensor should be
replaced every 2 years or more frequently depending on if the
sensor has been exposed to high or prolonged concentrations
of ammonia and/or it is not functioning as it should.
