Product details
1.Salinity sensor application environment description
Salinity sensor IP68 waterproof grade, RS485 digital interface, support MODBUS protocol, can be directly put into water to ensure long-term stability, reliability and accuracy of the sensor.It is used for environmental water quality testing and various high/low ionic strength water sample testing, and can meet the requirements of most industrial/environmental applications for online conductivity, salinity, and TDS 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
IP68 waterproof standard
24*1.218*1.5*228*22

3. Salinity sensor installation and electrical connection
1.Salinity 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. Electrical installation
The cable is a 4-core shielded wire:
Red - power cord blue/black - ground wire green - 485B yellow - 485A
Depending on the production batch, the color of the cable may be slightly different. Please refer to the cable screen printing for details.
Four. Salinity 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.
