Alarm unit WGA 06 for oil, petrol and grease separators
(oil-on-water alarm/overflow alarm).

Application
When used with the WGA-ÖW probe, WGA 06 detects accumulations of oil in separator sumps or shafts and generates an alarm before pollutants are discharged into the mains drainage system. It is also possible to connect the WGA-AS probe. It enables the detection of maximum levels in separators or retention tanks. This prevents overfilling that may be caused by clogged outlets or other circumstances. The unit keeps harmful substances from reaching the sewage water system.

Description
WGA 06 consists of an evaluation unit and a capacitance probe (WGA-ÖW or WGA-AS). The evaluation unit is equipped with 2 relay outputs, visual and audible alarms as well as test and re-set buttons. Either the floating probe WGA-ÖW or the fixed probe WGA-AS can be connected. WGA-ÖW floats on the surface of the water in the shaft and generates an alarm signal when an oil, grease or petrol layer of at least 15 mm thickness has built up. WGA-AS is mounted above the constant level of the separator or the retention tank. 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.
