The water contains soil, silt, fine organic matter and other microorganisms and colloids that cause turbidity in the water. Turbidity sensor is a sensor that detects the turbidity of water by measuring the degree of obstruction of suspended matter to light. The infrared wave transmitted by the emitter on the sensor is absorbed, reflected and scattered by the measured object during the transmission process, and a part of the transmitted light can be irradiated to the detector in the 180 °direction. The intensity of light received on the detector is related to the turbidity of the sewage being measured, so the turbidity of the sewage can be calculated by measuring the intensity of the transmitted light. It is widely used in chemical industry, electroplating, paper making, environmental protection water treatment engineering, pharmaceutical, food, tap water and other solutions turbidity monitoring. Especially suitable for outdoor and scene using .
Main Feature :
◇Digital submersible turbidity sensor , output RS485 and 4-20mA signal directly ◇Shell with 316 stainless steel material, with good corrosion resistance. ◇The stable invisible infrared light source is used to avoid the interference of the colorimetry in the liquid and the external visible light to the sensor measurement. ◇Using quartz glass lens with high transmittance in optical path, infrared wave emission and reception are more stable. ◇Wide range, stable measurement, high accuracy, good reproducibility, not affected by the flow rate and pressure of the sample. ◇Communication function :Two photoelectric isolation signals output, that is, RS-485 communication interface and 4-20mA current output , data acquisition can be carried out without instrument , direct connection computer , PLC , etc. with RS485 / 4 - 20mA signal interface ◇The sensor can be set up through RS485 communication, from slave address and baud rate, on-line calibration, factory reset, the corresponding range of 4-20ma output, Modification range, proportional coefficient and incremental compensation and so on. ◇Using three point correction way ◇The key components are imported from foreign famous brand . ◇ Power off protection >10 years.

◇ The new high qulaity shell is waterproof , dust-proof and damp-proof .
◇ Wide range , stable measurement , high accuracy , good repeatability and strong anti-jamming.
◇ Communication function : RS - 485 communication port witch can optional , photoelectric isolation 4-20mA analog output , the corresponding value can be set freely.
◇ Relay lag value can be set freely , avoid frequent action of switch relay. It has the function of setting the switch on and off .
◇ Adopting two-point correction method , the instrument measurement range can be modified.
◇ Watchdog function : Make sure the instrument dose not crash.
◇ The turbidity sensor is not affected by the flow rate and pressure of the sample.
◇ The infrared wave transmitted by the emitter on the sensor uses a stable invisible near monochromatic infrared light source to avoid the interference of the chroma in the liquid and the extemal visible light to the measurement of the sensor .
◇ The quartz glass lens with high transmittance is used in the optical path of the sensor , and the infrared wave is more stable to transimit and receive , and the photometric compensation is built in to improve the measuring accuracy.
