KST500 5000NTU Stainless Steel Probe DC24V Water Quality Sensor

KST500 316L stainless steel probe online turbidity meter turbidity sensor water treatment water quality

Production Introduction
The turbidity meter KXTX00 series,an online measuring instrument designed for the concentration of suspended solids.

Turbidity control is an important content of industrial water treatment, and is also an important water quality index.The turbidity of drinking water should not exceed 5 degrees according to different uses of water.It is required that the turbidity of supplementary water treated with circulating cooling water should be 2 ~ 5 degrees.The turbidity of inlet water (raw water) treated with desalted water should be less than 3 degrees;The manufacture of man-made fibres requires water to be less than 0.3 degrees turbid.Because the suspension and colloidal particles that constitute turbidity are generally stable and mostly have negative charge, they will not settle without chemical treatment.In industrial water treatment, the methods of coagulation, clarification and filtration are mainly used to reduce turbidity.

Recently, it is considered internationally that the standard of turbidity prepared with ullotropin-hydrazine sulfate has good reproducibility and is chosen as the uniform standard of FTU.1 ftu jtu = 1.Turbidity is an optical effect, the extent to which light is blocked as it passes through the water layer, indicating the water layer's ability to scatter and absorb light.
It is related not only to the content of suspended matter, but also to the composition, particle size, shape and surface reflectivity of impurities in water.

The measurement of light transmittance is easily affected by color absorption or particulate absorption.

Typical applications

It is used to measure the turbidity of water during the treatment of municipal sewage, industrial wastewater, and industrial slurry.
Measurement of turbidity of backwash water of filter in waterworks.
Turbidity measurement of water and sedimentation tank effluent;Industrial production process,
Water quality of circulating cooling water.

Measuring principle
 

The optical system of the turbidimeter consists of a tungsten filament lamp, a 90° detector for monitoring scattered light and a transmission light detector.The turbidimeter microprocessor calculates the signal ratio from the 90° detector and the transmission photodetector.The ratio calculation technique can correct the interference caused by chromaticity and light-absorbing substances (such as activated carbon) and compensate the influence caused by the fluctuation of light intensity, providing long-term calibration stability.The optical system of turbidimeter also requires to reduce the drifting light and improve the accuracy of test.

After the light wave sent by the transmitter on the turbidimeter sensor passes through the absorption, reflection and scattering of the measured objects in the transmission process, part of the transmitted light can illuminate the detector in the direction of 180° and part of the scattered light scatters to the detector in the direction of 90°.The light intensity received on the 180° and 90° direction detector has a certain relationship with the turbidity of the measured sewage, so the turbidity of the sewage can be calculated by measuring the intensity of transmitted light and scattered light.

Features:

1. The use of multi-beam mutual compensation technology can eliminate measurement errors caused by light window sticking, as well as temperature changes and components
Parts aging and other effects
2. LCD display, Chinese menu operation, stable performance, strong reliability, convenient operation for workers
3. The throw-in sensor is easy to install, has high accuracy, good repeatability and strong anti-interference ability
4. Support 485 communication 4-20mA analog output/support HART protocol/NB.GPRS.LORA communication (function option)
5. Complete product series, with corresponding sensors for different concentration ranges, and wide measurement range.

The sensors of the turbidity meter are mainly divided into three categories according to the different measuring ranges.
 

The input four-beam sensor is suitable for the measurement of high turbidity values.
Signal transmission and reception are relative, using multi-beam compensation method to calculate the current turbidity value,

It can also be used to measure the concentration of sludge, support different units, different ranges of customization.

Abbreviations table
NTU
The unit of turbidity is "degree", which is equivalent to the degree of turbidity produced by 1L water containing 1mg SiO2 (or white clay, diatomite), which is 1 degree, or Jackson.Turbidity unit is JTU, 1JTU=1mg/L white clay suspension.
The turbidity shown by modern instruments is the unit of scattering turbidity NTU, also known as TU.1NTU= 1JTU.
Recently, it is considered internationally that the standard of turbidity prepared with ullotropin-hydrazine sulfate has good reproducibility and is chosen as the uniform standard of FTU.1FTU=1JTU.
