Liquid level control relay sensors 16A 2P 1-100kOhm 3 (PZ-829 RC)

Two states (min/max). With adjustable sensitivity, the PZ-829 relays are used to detect the presence of electrically conductive liquids at the installation levels of flood detectors. They allow the maintenance of the minimum and maximum condition of the controlled liquid within the range specified by the user.

When the liquid level drops to the MIN state (i.e., the MIN and COM electrodes are open), the MIN contact will change to position 11-12, while the MAX contact remains at position 8-9. After reaching the MAX state (the MAX and COM electrodes are short-circuited), the MIN relay contact changes to position 11-10 and the MAX contact to position 8-7.
