Product introduction

The soil contains mud, silt, fine organic matter and other microorganisms and colloids to give turbidity in the water.The turbidity sensor is a sensor that detects the turbidity value of a water  by using the degree of hindrance that occurs when suspended matter in the water passes through the light.After the infrared light wave transmitted by the transmitter on the sensor is absorbed, reflected and scattered by the measured object during transmission, a part of the transmitted light can be irradiated to the detector in the 180° direction, and the intensity of the light received on the detector is measured and measured. The turbidity of sewage has a certain relationship, so the turbidity of sewage can be calculated by measuring the intensity of transmitted light. It is widely used in the monitoring of turbidity values in chemical, electroplating, paper making, environmental water treatment engineering, pharmaceutical, food, tap water and other solutions. Especially suitable for use in the field and on the spot.
 

 Main features

• This product is a submersible turbidity digital sensor, which can directly output RS485 signal and 4~20mA signal;
• The shell is made of 316L stainless steel and has good corrosion resistance.
• The transmitted light adopts a stable invisible near-monochromatic infrared light source, which avoids the interference of the chromaticity of the liquid and the visible light of the outside to the sensor measurement; and the built-in photometric compensation improves the measurement accuracy.
• The use of quartz glass lenses with extremely high transmittance on the optical path makes the emission and reception of infrared light waves more stable.
• Wide range of measurement, stable measurement, high precision, good reproducibility, not affected by sample flow rate and pressure
• Communication function:  RS-485 or 4~20mA
• The sensor can be set by RS485 communication, slave address and baud rate, online calibration, factory reset, 4-20mA output corresponding range, modified range, proportional coefficient and incremental compensation.
• Three-point correction.
• Watchdog function: make sure the meter doesn't crash.
• Power off protects > 10 years.
