Cross sensitivities for oil, solvents or hydrogen,
and thereby activated false alarms, are over now. The measurement
signal stays stable within a wide temperature range. The CI 21 can
be operated in temperature ranges of - 35 up to + 55ºC with a
tremendous accuracy. If there's an ammonia leakage the CI 21 reacts
quickly. In less than 8 seconds an alarm is activated. It doesn't
matter if you need to measure ammonia in a few ppm or up the Vol.%
range - the CI 21 allows for a wide range of applications, which other
sensors do not provide.
The Charge Carrier Injection Sensor CI 21 is based on a brand new
detection principle. The shortcomings of the established detection
methods initiated the development of new material adsorbing the
ammonia without the need of oxidation. With special micro-structured
electrodes the ammonia concentration can accurately be determined
over a large detection range. The cell does not get damaged or used
up and therefore a long life span is realized. Cross sensitivities
to other gases are clearly reduced with this method. Moreover, the
transmitter is fully functional in almost dry air and does not dry
out. Measuring errors by variations in temperature hardly occur.
The sensor reacts in less than eight seconds in case of ammonia
leakages.
