Jiwei Vibrating Rod Level Switch -- the Optimal Alumina Level Measurement

Level measurement in alumina industry is a major problem that troubles most manufacturers. However, as the vibrating rod level switch comes into the market, with its excellent structure design and performance, above measurement problem can be finally solved. So, what is the difficulty in measuring alumina level, and why Jiwei Tube-11 vibrating rod level switch is known as the most optimal level measurement for alumina industry?

Most users feedback that rotary paddle switch, RF admittance level switch, tuning fork level switch, single rod level switch and photoelectric switch all cannot measure alumina stably and reliably. As analysis, each specific performance in the measurement is shown in the following table:

Application of Different Level Switches in Alumina Industry

Lately, a large alumina group in Shandong Province entrusts the Institution of Petroleum and Chemical Industry to solve the measurement problem. By coincidence, the institution heard of the good performance and reputation of Jiwei Tube-11 vibrating rod level switch from another alumina manufacturer.

After few rounds comprehensive comparison of different type level switches from many manufacturers, the group contacts Jiwei. As few experiments finished, the installation position finally decided by Jiwei technical engineers. 

So far, all Tube-11and vibrating rod level switches successfully applied to the level measurement in the alumina project, and unaffected by the strong magnetic field or high ambient temperature.

Tube-11 vibrating level switch has the following advantages:

1. The circuit is modularized and potted with pouring sealant.

2. The software designed according to SIL requirements and has many functions such as automatic detection, automatic diagnosis and self-repair. Also, Tube-11 can accurately locate false information, improve the efficiency of false detection, and repair common faults independently.

3. Work reliably in strong magnetic field.

4. Large amount of low-temperature drift and high-precision electronic components are used, and the reliability of circuit and software designs are strengthened according to SIL requirements.

5. Highly sensitivity with measurable medium, the density can reach as low as 0.008 g/m³.

6. Well adapted to medium with changing humidity and dielectric constant;

7. Process temperature can reach up to 250℃, which is industry-leading;

8. Got Ex-approval/Intrinsic Safe certification & IP66/67 ingress protection.
