Precautions for maintenance of online sludge concentration meter

by:BOQU     2023-04-10
It is very important for us to pay attention to the maintenance and maintenance of the equipment in the daily use of the online sludge concentration meter. Correct maintenance can reduce the damage and failure frequency of the online sludge concentration meter equipment. And it can effectively improve the service life of the equipment. Today, the online sludge concentration meter editor will explain it in detail for everyone. (1) Online sludge concentration meter transmitter maintenance The online sludge concentration meter adopts multi-beam mutual compensation technology , It can eliminate the measurement error caused by the sticking and dirt of the sensor light window, as well as the influence of temperature change and device aging, and realize stable and accurate measurement. The online sludge concentration meter is composed of two parts, the transmitter and the sensor. The maintenance of the online sludge concentration meter is carried out from three aspects: transmitter maintenance, sensor maintenance and communication maintenance. According to the requirements of use, the installation location and working conditions of the online sludge concentration meter transmitter are relatively complicated. In order to make the transmitter work normally, maintenance personnel need to perform regular maintenance on the transmitter. Please pay attention to the following items during maintenance: 1. Installation Outdoors, please check whether there is water leakage in the installation box of the online sludge concentration meter transmitter; 2. Check the working environment of the transmitter. If the temperature exceeds the working rated range of the online sludge concentration meter transmitter, pay attention to Do not let moisture enter the inside of the transmitter 3. Check whether the data displayed by the transmitter is normal; 4. Check whether the wiring on the transmitter terminal is firm. Note that the 220V AC power supply should be disconnected before removing the wiring cover. (2) Maintenance of the online sludge concentration meter sensor In order to obtain the best measurement results, the online sludge concentration meter sensor needs to be regularly maintained. Please pay attention to the following items during maintenance: 1. The small column on the online sludge concentration meter sensor needs to be cleaned regularly. It is recommended to clean the sensor every 2-3 weeks to ensure that the small column of the sensor is clean; 2. Check the cable of the sensor. The cable of the online sludge concentration meter should not be tight during normal operation, otherwise it is easy to break the wire inside the cable and cause the sensor to not work normally. ;3. Check whether the shell of the sensor is damaged due to corrosion or other reasons; 4. Check whether the plug and socket of the connecting cable between the sensor and the transmitter are loose.
