Application
Oil and petrol pose a great danger to groundwater and waste water.
WGA 01 monitors the level of the separated liquid in oil/petrol separators
and generates an alarm signal when it is necessary to empty
the separator. In addition, the maximum level in the separator can be
detected. 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 01 consists of an evaluation unit, a capacitance probe (WGAES4)
for detecting the layer level as well as an optional additional PTC
thermistor probe (WGA-R6) for detecting the maximum level (overflow
alarm). The evaluation unit is equipped with 2 relay outputs,
visual and audible alarms as well as test and re-set buttons. The WGAES4
probe is mounted at least 150 mm below the constant level of the
separator. As soon as the oil or petrol layer reaches the critical
level, the unit generates an alarm signal. By installing an additional
optional WGA-R6 probe above the constant level, the maximum permissible
level in the separator can also be detected. The evaluation
unit monitors the connected probes and signals short circuits or
cable breaks in the probe circuits.
