Fluid level control relay PZ-831 RC
Three-position liquid level control relay.
With sensitivity adjustment.
The PZ-831 RC relay detects the presence of electrically conductive liquids at the levels at which the flood probes are installed. It enables the minimum and maximum levels of the monitored liquid to be maintained within a specified range.
PLEASE NOTE – not suitable for measuring rainwater levels. If you are looking for a transmitter to measure rainwater levels, we recommend the PZ-829 RC-WD
Operation
In the dry state (all probes open), all relay contacts are open. A short circuit caused by liquid between the COM base probe and the next level probe will cause the relay contact assigned to that probe to close. For example, when the first level probe R1 is submerged, the base probe COM and the level probe R1 will be short-circuited . This will cause contacts 11–12 to close. The same applies to level probes R2 and R3. When the liquid level drops below a level probe (causing the base probe COM and the level probe to open), this will open the contact assigned to that probe.
How to connect the probes
Electrode probes (4 pcs) are connected using a cable with a conductor cross-section of up to 1 mm² and a maximum length of 100 m.
Note!
Terminals 3-4-5-6 are galvanically isolated from the mains.
