AQUIS500
Water & Brine Detector
- Detect ammonia leaks
- Measure in water and brine mixtures
- Measure low concentrations
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 pH-dependent 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.
TECHNICAL DATA:
