Level monitoring relays
Overview
They monitor the level of conductive liquids in wells, tanks, reservoirs, etc. They can monitor from one to six levels of water with optional fill / drain functions. These are either separately marketable products, or directly involved in the setup with a contactor or motor starter.
Product detail
DESCRIPTION
- 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
