one.Water transparency sensor application environment description
water transparency sensor is suitable for online monitoring of water transparency in inland rivers, lakes and reservoirs, surface water in cities and aquaculture industries.The scattering or absorption properties of light are used to measure transparency in water.It has high sensitivity, fast response and real-time monitoring capabilities, and is widely used in water quality monitoring and sewage treatment.
Signal output: RS485 (MODBUS-RTU).
Infrared LED light source, strong anti-interference ability.
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

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.
In the monitoring of soil erosion in runoff plots and small watersheds, the traditional manual measurement model has long faced numerous bottlenecks. Staff need to carry various instruments to and from monitoring points, not only to conduct flow observations in complex terrain but also to manually c...
The microclimate of farmland refers to the small-scale climatic environment formed by the interaction among the surface air layer, soil layer and crop population in the farmland. It is reflected by the values of agricultural meteorological elements such as radiation, air temperature and humidity, wi...
