The conductivity controller LRR 1-50, LRR 1-51 in conjunction with conductivity electrodes LRG 1.-.. and conductivity
transmitter LRGT 1.-.. is used as conductivity controller and limit switch, for instance in steam boilers, (pressurized) hot water installations as well as condensate and feedwater tanks. The conductivity controller indicates when the MAX
conductivity limit is reached and opens or closes a continuous blowdown valve.

The conductivity controller LRR 1-50, LRR 1-51 can be used together with conductivity electrodes and transmitters in the following equipment combinations: Conductivity controller LRR 1-50 together with conductivity electrodes LRG 12-2, LRG 16-4, LRG 16-9, LRG 17-1 and LRG 19-1;

Conductivity controller LRR 1-51 together with conductivity transmitters LRGT 16-1, LRGT 16-2 and LRGT 17-1.
