Single state liquid level control relay with sensitivity adjustment for rainwater
- Single state liquid level control relay with sensitivity adjustment for rainwater
Single state liquid level control relay with sensitivity adjustment for rainwater
-for rainwater level control,
- with sensitivity adjustment,
- two-state (min/max),
- 3 x PZ2 probe.
PZ-829 relays detect the presence of electrically conductive liquids at flood probe mounting levels.
They maintain the minimum and maximum states of the controlled liquid within the range set by the user.
Operation
When the liquid level drops to the MIN state (i.e., MIN and COM electrodes open), the MIN contact will be switched to the 11-12 position; the MAX contact remains in the 8-9 position. When the MAX state is reached (MAX and COM electrodes closed), the MIN relay contact is switched to the 11-10 position, and the MAX contact is switched to the 8-7 position.
