Alarma de nivel por capa/ alarma de sobre flujo
Alarm units WGA 02/WGA 03 for oil, petrol and grease separators
(layer level alarm/overflow alarm).
Oil, grease and petrol pose a great danger to groundwater and waste water. WGA 02 monitors the thickness of the layer of separated liquid in oil, petrol and grease separators and generates an alarm signal when it is necessary to empty the separator. WGA 03 can also detect the maximum level in the separator. This prevents overfilling caused by clogged outlets or other circumstances. The unit prevents harmful substances from being discharged into the mains drainage system.
Description WGA 02 consists of an evaluation unit and a conductivity probe (WGA-SD) for detecting the separating layer level. The evaluation unit is equipped with 2 relay outputs, visual and audible alarms as well as test and re-set buttons. The WGA-SD probe is mounted below the constant level of the separator. As soon as the oil, petrol or grease layer reaches the critical level, the unit generates an alarm signal. WGA 03 is equipped with an additional capacitance probe (WGAAS). This is mounted above the constant level. An alarm is triggered when the maximum permissible level is reached. The evaluation unit monitors the connected probes and signals short circuits or cable breaks in the probe circuits.
