The relay, which is used to control the level liquids conductive (water, chemical solutions,
food, etc.).
In this principle, it goes on about the measurement of liquids by measuring probes. As the
measuring used signal is 5 V AC / 500 Hz. Using an AC signal prevents the the increasing
oxidation of probes and unwanted polarization and electrolysis liquid. During depending
on the DIP settings confi gurations, switches can control two independent levels or use a
combined function for one level (see diagram of functions).
The relay is equipped with regulation of the sensitivity to to liquid resistance. It's also
possible to eliminate some of the unwanted switching in the sensitivity settings according
to specifi c conditions (for example, pollution probe sediments, humidity, etc.). It's also
possible for each probe to set the delay in the range of 0.5 - 10 s, and using the DIP switch
type delay (when you turn the relay on and off , depending on application).
