Once a user who just contacted the radar level meter, the first time when using the measurement process there were some problems, very confused. In fact, many new users may have such a problem, in fact, whether it is a high-frequency radar level meter, guide wave radar level meter, or low-frequency radar level meter, the measurement of the problem is a normal phenomenon.
To use an analogy, people can get sick, let alone the instrument. The most important thing is to find the cause and solve the problem in time.
Today, we will understand the problems and solutions in the measurement of the meter together through a case of conductive carbon black measured by the guided wave radar level meter.
Conductive carbon black is a carbon black with low resistance or high resistance properties, which can give products a conductive or anti-static effect. It is characterized by small particle size, large and rough specific surface area, high structure, clean surface, etc. Carbon black with carbon black, carbon black itself is a semiconductor material, conductive carbon black has a low resistivity, can make rubber or plastic with certain conductive properties, used in different conductive or antistatic products, such as antistatic or conductive rubber, plastic products, cable material; can also do the raw material of the dry cell.
Conductive carbon black according to its conductive properties and manufacturing methods can be divided into conductive slot black, conductive furnace method carbon black, superconducting furnace method carbon black, special conductive furnace method carbon black, etc., acetylene carbon black also good conductivity of carbon black.
A company user needs to measure conductive carbon black, after understanding, the site environment is better, our engineer suggested using our guide wave radar level meter RD701, using contact measurement, the stability and accuracy of measuring carbon black are guaranteed.
The measuring range is about 1.5 meters, after using it for a long time, the customer feedback that there is a fault that cannot be solved by themselves, obviously there is no material in the bin, but the meter shows that there is still more than 0.5 meters of material level height, so they turn to us for help.
Initially, our after-sales engineer thought that there was a problem with the installation and commissioning of the master on-site, and after the master on-site patiently followed the steps instructed by the after-sales engineer to commission the meter, the problem still could not be solved.
Then we suspected that there was a baffle in the silo, which caused a false echo, but there was no obstacle in the silo, and finally, this suspicion was also ruled out. After several tests and analyses by the after-sales engineer, it was found that the magnetic field below was too strong and the wave-guide rod was magnetized, causing the problem to appear.
Through this case we can also clearly find that the wave guide rod will be affected by the magnetic field, users who have problems in this area can refer to.
In addition, professional engineers in finding the problem is to constantly figure out to exclude, anything is not a one-time success. This measurement of conductive carbon black is so, the next measurement of other media, the face of other working conditions is also the case.
