Digital MLSS Turbidity Sensor of swimming water NS-ML683 testing turbidity swimming water
Product introduction：
The sludge concentration digital sensor uses specific infrared light processing technology. The light sent by the infrared transmitter is transmitted through the medium and irradiated on the detector to obtain relevant data. Then, by analyzing these data signals, the accurate concentration of suspended solids in the medium can be obtained; when measuring low range and high range, the same Accuracy and continuity. And the sensor has built-in luminosity compensation, which effectively eliminates the deviation caused by changes in certain environmental factors, and can be used in more environments. It is widely used in monitoring MLSS value in solutions such as chemical industry, electroplating, papermaking, environmental protection water treatment engineering, pharmacy, food, and tap water. Especially suitable for use in the field and on-site.

Main features：
It is a submersible MLSS 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: two optical isolation signal output, namely RS-485 communication interface (partially compatible with MODBUS-RTU protocol), the communication interval is up to 50ms; and 4~20 mA current output, 4-20mA can be reverse output; no need The instrument can directly connect to computers, PLCs and other devices with RS485/4-20mA signal interface for data acquisition. It is convenient for users to integrate the sensor into the industrial control environment such as the upper computer system and the physical connection system.
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.
