online turbidity sensor 20mA

Product Description

Water Quality Analysis Online Turbidity Probe RS485 Turbidity Sensor 4-20mA Output Turbidity Meter Accuracy 

Product Description
Our turbidity sensors use fiber optic technology to provide superior repeatability and stability, and are less susceptible to ambient light. The automatic cleaning brush with the sensor can effectively eliminate air bubbles and reduce the influence of contamination on the measurement. It has a longer maintenance period and maintains excellent stability for long-term online use.
* Digital sensor, RS-485 output, support MODBUS
* With automatic cleaning brush to prevent contamination and eliminate air bubbles
* Strong anti-interference ability, free from ambient light and chromaticity
* 90° scattered light principle, with fiber optic technology for better repeatability

Maintenance method

①The outer surface of the sensor: clean the outer surface of the sensor with tap water. If there are still debris remaining, wipe it with a moist soft cloth. For some stubborn dirt, you can add some cleaning fluid to the tap water to rinse.

②Check the cable of the sensor: the cable should not be taut during normal operation, otherwise the internal wires of the cable may break, causing the sensor to fail to work normally.

③Check whether the electrode or light window of the sensor is dirty, whether the cleaning brush is normal, and whether the electrode is normal.

④Check whether the cleaning brush (if any) of the sensor is damaged and whether it can work normally.

⑤Continuous use for more than 18 months, (as the case may be) return to the factory to replace the dynamic sealing device.
