Automatic Cleaning Function Online Digital RS485 Turbidity Sensor MLSS Probe

NTDS937 Digital Turbidity Sensor with Auto Cleaning Function  

1. The internal upgrade of the sensor can effectively prevent the internal circuit from dampness and dust accumulation, and avoid damage to the internal circuit.

2. The transmitted light adopts stable invisible near-monochromatic infrared light source, which avoids the interference of chroma in liquid and external visible light to sensor measurement.And built-in luminosity compensation, improve the measurement accuracy.

3. The use of quartz glass lens with high light transmittance in the optical path makes the transmission and reception of infrared light waves more stable.

4. Wide range, stable measurement, high precision, good reproducibility.

5. Communication functions: Two photoelectric isolation signal output, one RS-485 communication interface (Modbus-RTU protocol compatible), the fastest communication interval is 50ms.One way 4 ~ 20mA current output, 4-20mA can reverse output; No instrument, can be directly connected to computers, PLC and other devices with RS485/4-20mA signal interface for data acquisition.It is convenient for users to integrate the sensor into the upper computer system and the IoT system and other industrial control environment.

6. Without meter, the sensor can be set online through software, from the machine address and baud rate, online calibration, restore factory, 4-20mA output corresponding range, modify the range, proportional coefficient and incremental compensation Settings.
