2.Water transparent sensor size diagram
three.Water transparent sensor installation and electrical connection
1.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 5-core shielded wire, line sequence definition: brown-power cord (12~24VDC)
Black-ground (GND)
Blue-485A Green-485B
Yellow - 4-20mA current output (can be suspended if not used)
Before powering on, carefully check the wiring sequence to avoid unnecessary losses caused by wiring errors.
Four.Water transparency 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: Use a soft brush to remove attachments (be careful to avoid scratching the electrode surface), then clean with distilled water, and then perform calibration operations.
