Alarm unit for separators WGA 02

Data sheet Alarm unit for separators WGA 02

Benefits

For oil, petrol and grease separators
Layer thickness/overflow alarm
With EX approval for zone 0

Application

Oil, grease and petrol pose a great hazard 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 time to drain the separator. WGA 03 can additionally detect the maximum level in the separator. This avoids overfilling that may be caused by clogged outlets or other circumstances. The unit keeps harmful substances from reaching the sewage water system.

Description

WGA 02 consists of a control unit and a conductivity probe (WGA-SD 03) for monitoring the oil or grease layer. The control unit is equipped with 2 relay outputs, visual and audible alarms as well as Test and Acknowledge buttons. The WGA-SD 03 probe is mounted below the constant level of the separator. As soon as the oil, petrol or grease layer reaches the critical level, the device generates an alarm signal. WGA 03 is equipped with an additional capacitance probe (WGA-AS). It is mounted above the constant level. An alarm is triggered when the maximum level is reached. The control unit monitors the probes for short circuits or line interruptions.
