Sludge concentration sensor

Sludge concentration sensorIt is a device specifically designed to measure the solid particle content in sludge, often using optical scattering or ultrasonic principles. Optical type calculates concentration by emitting specific wavelength light and detecting the scattered light intensity of sludge particles; Ultrasonic type uses the propagation speed and attenuation degree of sound waves in sludge to reflect concentration. It has the advantages of precise measurement, fast response, and good stability, and can monitor sludge concentration in real-time online. It is widely used in sewage treatment plants, sludge treatment and disposal scenarios, and provides key data support for the optimization and adjustment of sludge treatment processes and equipment operation control.

2、 Technical performance and specifications

1. Technical parameters

2. Dimensional drawing

The sensor connector is an M12 aviation plug connector with a 5-pin female socket

3、 Installation and electrical connections

1. Installation

Installation distance requirement: Keep at least 5cm from the side wall and at least 10cm from the bottom.

2. Electrical installation

The cable is a 4-core shielded wire, and the line sequence is defined as follows:

Red - Power cord (12~24VDC)

Blue - Ground (GND)

Green -485B

Yellow -485A

Before powering on, carefully check the wiring sequence to avoid unnecessary losses caused by wiring errors.

Note: The color of the cable may vary slightly depending on the production batch. Please refer to the cable silk screen printing for details

4、 Maintenance and upkeep

1. Use and maintenance

The measurement window of a sensor is one of the key components to ensure its normal operation and accurate measurement. The cleanliness requirements are crucial to ensure the accuracy and reliability of the measurement.

1.1 Maintenance Methods

1. Regular cleaning: The measuring window should be cleaned regularly to remove dirt, sediment, and other impurities attached to the surface. The cleaning frequency depends on the measurement environment, but it is usually recommended to clean daily or weekly.

2. Use gentle cleaning agents: When cleaning, choose gentle cleaning agents and avoid using cleaning agents containing abrasives or acidic or alkaline components to prevent damage to the surface of the measurement window.

3. Soft cloth or sponge: During the cleaning process, a soft cloth or sponge should be used to gently wipe the surface of the measuring window to prevent scratches or wear.

4. Avoid direct contact: During the cleaning process, avoid direct hand contact with the surface of the measurement window to reduce contamination from fingerprints and grease.

5. Rinse: After cleaning, rinse the measuring window with clean water to ensure the removal of residual cleaning agents and dirt.

6. Drying: After cleaning, gently wipe the surface of the measuring window with a dry soft cloth to remove water stains and ensure dryness.

7. Regular inspection: Regularly inspect the surface of the measurement window for damage or wear to maintain the normal operation of the sensor.

8. Avoid exposure to chemicals and high temperature environments: Avoid exposing the measurement window to harmful chemicals or high temperature environments to prevent damage or corrosion to its surface. When the sensor is used for a long time and measurement errors occur, calibration and correction can be carried out by cooperating with the instrument. If the sensor cannot be calibrated and measured through the above methods of maintenance and upkeep, it indicates that the sensor has failed and should be replaced.

1.2 Precautions

1. The measurement window contains glass components, so sharp or hard objects should be avoided from scratching the surface to prevent scratches and damage.

2. It contains sensitive optical components and precision electronic equipment inside, avoiding exposing the sensor to severe vibration or impact to prevent displacement or damage of the optical parts and electronic equipment. No maintenance is required inside the device.

When not in use, appropriate dust covers or sleeves should be used to protect the optical parts from dust and pollutants.
