1.Salinity sensor application environment description
Salinity sensor easily and accurately measures the total dissolved salt content in aqueous solutions and is used in aquaculture, water source testing, sewage treatment and other fields.It is used for environmental water quality detection and various high/low ionic strength water sample testing, which 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 has strong interference.
Good reproducibility, thermal stability, low drift, small size, fast response speed
Easy to install, simple, 3/4NPT pipe threads, easy to sink-in installation or install 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 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:
Since ancient times, agriculture has been the industry most closely tied to natural conditions, with "relying on heaven for food" being the most authentic portrayal of farmers. Traditional agricultural production heavily relies on personal experience and passed-down farming proverbs to pre...
Soil electrical conductivity (EC) is a critical indicator for measuring the content of soluble salts in soil, reflecting the total concentration of various ions in the soil solution or the ionic strength of water-soluble substances. When salts in the soil dissolve, they exist in ionic form—the high...
Climate change is leading to more frequent and intense extreme weather events (such as droughts, floods, heatwaves, and late spring cold snaps). These weather events cause devastating impacts on agricultural production. Traditional, experience-dependent farming models struggle to cope with this unce...
This fully automatic online hydrological monitoring system is based on microwave technology. It employs K-band planar radar technology to non-contactly measure water level, flow velocity, flow rate, and rainfall within channels. The system's built-in algorithm calculates cross-sectional fl...
