2. Water quality conductivity sensor dimensions
The sensor connector is an M12 aviation plug connector with 5 pins.
3. Water quality conductivity sensor installation and electrical connection
1. Installation
Note: The sensor cannot be installed upside down or horizontally, but must be installed at an angle of at least 15 degrees.
2. Electrical installation
The cable is a 5-core shielded cable, line sequence definition: Brown - power line (12~24VDC)
Black - Ground (GND)
Blue-485A Green-485B
Yellow - 4-20mA current output (can be left floating if not used)
The wiring sequence should be carefully checked before powering on to avoid unnecessary losses due to wiring errors.
4. Water quality conductivity sensor maintenance and care
1. Use and maintenance
Conventional electrodes need to be cleaned and calibrated periodically. The maintenance cycle is determined by the customer based on their working conditions. Conventional electrode cleaning method: 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.
