In the actual working conditions, because the radar level meter measuring object is more complex, subject to high temperature, high pressure, and high corrosion, measurement at the same time accompanied by foam, stirring, steam, and other complex conditions, resulting in frequent failures of the radar level meter, short maintenance cycle, affecting production.
Then, the specific understanding of the radar level meter prone to failure and its solution frxdfzsaV hmkj1 method becomes very critical. In addition to the solutions below you can also take a look at our high-tech self-heating radar level meter, which is automatically heated in cold weather to prevent the level meter from becoming paralyzed. It is also crystallization-proof and dust-proof.
1. Check whether the power supply is normal
When the level of the radar level meter reaches a certain value after the change is very slow, you should check the power supply, whether the normal power supply, and whether the normal output after the power supply. When the liquid level does not change, then you should check whether the fuse of the equipment is blown, if there is no current output, then the instrument has a problem.
2. Use of lifting temperature
In order to ensure the measurement effect, the internal temperature of the radar level meter should be lower than 50°C. If the internal temperature exceeds this value, a small amount of wind can be blown to the instrument head, the scientific temperature. Avoid using ice water for cooling, ice water not only fails to achieve the effect of cooling but may also lead to paralysis of the radar level meter.
3. Inaccurate display value
Inaccurate display value is the most common problem of radar level meter, the cause may be the initial setting is not the appropriate or plug-in connection is not correct, the phase in the mediation is still not improved, then to check in detail whether the output current of the radar level meter is normal, the inspection found that the output current is greater than 22mA, then the display module is faulty. If the output current is less than 3.5mA, then the electronic module is faulty.
4. System displays error messages
When the system frequently displays an error message, it needs to be reset and recalibrated. The cause is due to a sudden power failure during data storage. If there is no change after the reset and recalibration, then the electronic module of the radar level meter needs to be checked.
5. Antenna staining, crystallization
When the radar level meter is due to antenna staining, crystallization, or failure, the need to clean the antenna, power it off, dismantle the instrument tilt down, wipe off the attachment with a rag, do not use iron scraping, do not bend the antenna, pay attention to lightly hold and lightly put, so as not to damage the antenna epidermis.
