Līmeņa relejs HRH-8, 230 VAC

Relay is designed to control the level of conductive liquids in wells, tanks, pools, tankers, reservoirs,... (replacement HRH-1).
Galvanically isolated supply and guard circuits.
Within one device, the following confi gurations can be selected:
- 2x one-level monitoring (in separate tanks)
- 1x two-level monitoring (in one tank) - pumping from one tank to another.
DIP switch selection on the front panel (8 functions).
Adjustable probe sensitivity (for each probe separately).
Adjustable relay switching delay (for each probe separately).
10 Hz watch frequency prevents polarization of the liquid and increases resistance to interference by network frequency
