Aquis500 – For detection in water and brine
General
The Aquis system is developed for detection of ammonia
leaks in refrigeration systems. The development of this
robust and practical system is based on many years of
experience can be used for water as well as "brine".
The sensor can be used to measure ammonia (NH3) in
water. In an aqueous solution, ammonia is in a pHdependent equilibrium with the ammonium ion (NH4+
ions). Since the NH4+ ions are converted to ammonia
when adding lye, the sensor can detect ammonia. (the
NH4+ ions are not detected)
The ammonia sensor consists of a pH glass electrode
and a reference electrode. Both electrodes are positioned
in an electrolyte. The electrolyte is separated from the
test medium with a hydrophobic, gas permeable
membrane.
The local change in pH value is measured at the high
resistance of the integrated pH electrode.
The monitoring unit provides a 4..20mA output, which can
be connected to an external PLC.
Different sensor can be connected to the Aquis500
depending on the application and pressure in the system.
The sensors can be quickly and easily installed.
