Detailed information on DSX100 online turbidity meter and turbidity meter:

1Product Features

lThe turbidity transmitter consists of an electronic unit and a measuring unit (including a measuring tank and auxiliary devices). This product has the characteristics of no calibration, high accuracy, and low power consumption. The transmitter has automatic temperature compensation function.

lThe waterway system automatically adjusts the pressure and flow rate of the measured water sample, allowing the water sample to flow into the measuring tank at a constant flow rate and improving the stability of the instrument.

lIt can automatically eliminate bubbles in the tested water sample, making the instrument's reading more accurate.

lThe light source adopts laser light source, which is stable and has a longer lifespan than LED, up to 100000 hours. It has low power consumption, energy saving and environmental protection.

lAnalog output 4-20mA standard signal

lEquipped with upper and lower limit alarm function, the upper and lower limit alarms have two independent relay output controls, and the hysteresis value is independently adjustable.

lIt has two display modes: digital display and waveform display. The digital display mode has upper and lower limit alarm display and time and date display. The waveform display mode can automatically adjust the display range based on the upper and lower limit alarm values.

lThe value of offset b can be adjusted according to the formula y=kx+b, and the positive and negative values of the offset can be adjusted.

lEquipped with waveform recording function, it can continuously record waveform data for two months (60 days) and view historical data.

lIn addition to the transmission function, the transmitter also has an isolation function. The input and output signals of the sensor are isolated using a linear optocoupler circuit, effectively ensuring the stability of the signal. After processing the turbidity voltage signal, the transmitter performs temperature compensation and outputs a standard signal for measuring turbidity in the solution.

IIInstallation requirements

⑴The entire instrument is a three-dimensional wall mounted device that must be installed on a flat, dry, ventilated, vibration free, and corrosion-resistant surface

Gas and liquid on the wall.

⑵The instrument should be installed in a convenient location for drainage and water sample collection.

⑶The instrument installation should be perpendicular to the ground and not tilted.

⑷Do not install the instrument in places with strong direct sunlight or electromagnetic interference.

⑸The pipes connecting the inlet and outlet of the instrument should be firm.

IIIWorking principle of sensors

The turbidity sensor adopts the principle of surface scattering and is divided into two parts, a laser light source and a photodetector. laser light source

The stability directly affects the accuracy and reproducibility of measuring instruments.Using halogen tungsten lamp as the light source for turbidity meterLife span only

It takes hundreds to thousands of hours, and using laser components not only saves energy and is environmentally friendly, but also increases the lifespan to 100000 hours

At that time. So we choose laser components as the light source, and the beam emitted by the laser is incident at a certain angle to the horizontal plane

In water, the photovoltaic cell is located above the water surface, and its direction is at a 90 degree angle to the laser beam. The scattering received varies in turbidity

Due to different light intensity, the sensor processes the changed signal into current signal and transmits it. Photodetectors and

Laser light sources do not come into contact with water and do not need to be cleaned during use.

5、 Calibration and cleaning of instruments

1. Calibration (two-point calibration)

This instrument has been calibrated before leaving the factory. Generally, users do not need to calibrate it. After installation, power on for about 30 minutes

If it can work stably, users can verify the self-test values.

Calibration instrument is the key to the use of this instrument, and it must be carefully and meticulously followed strictly according to the operating steps, otherwise it may cause problems

A huge error.
