Relay is designed for monitoring levels in wells, basins, reservoirs, tanks...
In one device you can choose the following confi gurations:
- one-level switch of conductive liquids (by connecting H and D)
- two-level switch of conductive liquids
One-state device monitors one level, two-state device monitors two levels (switches on one level
and switches off on another level)
Choice of function PUMP UP, PUMP DOWN
Adjustable time delay on the output (0.5 - 10s)
Sensitivity adjustable by a potentiometer (5-100kΩ)
Measuring frequency 10Hz prevents polarization of liquid and raising oxidation of measuring probes

Device description
Technical parameters
Tank with
monitored level
Relay is designated for monitoring of levels of conductive liquids with possibility of functions: PUMP UP
or PUMP DOWN. To prevent polarization and liquid electrolysis of liquid, and undesirable oxidation of
measuring probes, alternating current is used. For measuring use three measuring probes: H- upper level,
D- lower level, C - common probe. In case you use a tank made of a conductive material, you can use
it as probe C. In case you require monitoring of one level only, it is neccessary to connect inputs H and
D and connect them to one probe - in this case sensitivity is lowered by half (2.5... 50kΩ). Probe C can
be connected with a protective wire of supply system (PE). To prevent undesirable switching out output
contacts by various infl uences (sediment on probes, humidity...) it is possible to set sensitivity of the device
according to conductivity of monitored liguid (corresponding to “resistance” of liquid) range 5 up to 100kΩ.
To reduce infuences of undesirable switching of output contacts by liquid gorgle in tanks, it is possible to set
delay of output reaction 0.5 - 10s.
