Senect - Model One-A2-13 - Multifunctional Aquaculture Controller Brochure

Measurement of the oxygen concentration with the low-maintenance and long-term stable optical SENECT O₂-Sensor O2S. If the oxygen concentration sinks below a treshhold, an aerator or solenoid valve depending on the aeration mode is switched on (24 v DC devices directly, 230 V AC devices via the optional Power Switch). Multiple regulations are possible! For example, if the oxygen concentration falls below 70% saturation, an aerator is switched on. If the oxygen concentration falls further to less than 60%, additionally technical oxygen supply is switched on via a solenoid valve.
