Series N & CLKA — conductive level probes

• For conductive liquids • 1 to 3 adjustable electrodes • Simple to use • Maximum level 2 metres • Economical solution For level control in open or closed tanks and for leak and flood detection; used with an ES2001 relay they control emptying and filling. A small current is sent through a so-called reference electrode, which may also be the tank itself when it is metal. When the liquid touches the reference electrode and another electrode set at the level to be detected, current flows between the 2 electrodes. The ES2001 relay detects this short circuit and closes a contact to raise an alarm. If required, the electrode models are cut to length.
