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.
