The ingress of foreign matter such as alkalis, acids, raw water, dyeing baths, etc., which increase conductivity, is detected and reported quickly and reliably by the systems LRG 16-9/LRS 1-7 or LRGT/URS 2. The necessary action is instigated automatically. The systems work on the principle of automatic temperature compensation, so that fluctuating temperatures do not result in false alarms.
They are employed in pressurized steam and hot-water plants, e.g. for monitoring condensate or feedwater.
