Product details
one. Water quality conductivity sensor application environment description
Water quality conductivity sensor monitors changes in water quality by measuring the electrical conductivity of water and is used to assess the total amount of dissolved ions in water.It is used for environmental water quality testing and testing of various high/low ionic strength water samples, and can meet the requirements of most industrial/environmental applications for online conductivity measurement.
Signal output: RS485 (MODBUS-RTU).
Internal signal isolation technology, strong interference resistance.
Good reproducibility, thermal stability, low drift, small size, fast response
Easy and simple installation, 3/4NPT pipe thread, convenient for submersible installation or installation in pipes and tanks
Stable performance and long service life

three. Water quality conductivity sensor installation and electrical connections
1.Water quality conductivity sensor installation
Note: The sensor cannot be installed upside down or horizontally, and must be installed at an angle of at least 15 degrees.
2.Water quality conductivity sensor electrical installation
The cable is a 5-core shielded wire, wire sequence definition: brown - power cord (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 caused by wiring errors.
Four. Water quality conductivity sensor maintenance and care
1.Use and maintenance
Conventional electrodes require periodic cleaning and calibration, and the maintenance cycle is determined by the customer based on his or her own 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.
