The turbidity value of seawater refers to the density and size of suspended particles in seawater, which include algae, sand, sediment, microorganisms, etc. Monitoring the turbidity value of seawater can help us understand the concentration and type of suspended matter in seawater, thereby judging the water quality and ecological environment of seawater.
The Turbidity Sensor used in seawater need to pay attention to the following aspects:
1. Measuring range: Different turbidity sensors have different measuring ranges, and the appropriate sensor needs to be selected according to actual needs.
2. Precision and accuracy: The precision and accuracy of the turbidity sensor directly affect the reliability of the measurement results, so it is necessary to select a sensor with high precision and high accuracy.
3. Stability and reliability: The seawater environment is complex and changeable, and the turbidity sensor needs to have good stability and reliability, and be able to work stably and maintain accuracy for a long time.
4. Anti-interference ability: There are many interference factors in seawater, such as ocean currents, waves, light, etc. Turbidity sensors need to have good anti-interference ability to accurately measure the concentration of suspended solids in seawater.
5. Maintenance and maintenance: The turbidity sensor needs regular maintenance and maintenance, including cleaning, calibration, replacement of parts, etc., to ensure the long-term stable operation of the sensor.
The measurement range of OPTU790 infrared water turbidity sensor is 0~1000NTU. It adopts the principle of infrared scattering. The digital sensor has RS485 interface and supports Modbus. Internal storage of calibration data, plug and play. This turbidity sensor has a small shape, the outer shell is PPS, and the inner is titanium alloy. If it is used in seawater, it can resist corrosion and the impact of waves. Flat head for easy cleaning and maintenance.
