1.Salinity sensor installation
Note: The sensor cannot be installed inverted or horizontally when installed, and should be installed at least 15 degrees above the angle of inclination.
2.Electrical installation
The cable is a 4-core shielded wire:
Red—Power cable blue/black—Ground cable green—485B yellow—485A
Different production batches, the cable colors vary slightly.Please refer to cable silkscreen for details.
Four.Salinity sensor maintenance and maintenance
1.Use and maintain
Conventional electrodes require periodic cleaning and calibration, and the maintenance cycle is determined by the customer according to their working conditions.Conventional electrode cleaning methods:
