Jiwei Vibrating Rod Level Switch — the Optimal Alumina Level Measurement
Level Measurement in the Alumina Industry
Level measurement in the alumina industry presents significant challenges for most manufacturers. However, the introduction of the Jiwei Tube-11 vibrating rod level switch, with its excellent structural design and performance, has provided an effective solution to these measurement issues. Let’s explore the challenges associated with alumina level measurement and understand why the Jiwei Tube-11 vibrating rod level switch is considered the most optimal level measurement solution in the alumina industry.
Most users report that rotary paddle switches, RF admittance level switches, tuning fork level switches, single rod level switches, and photoelectric switches all fail to measure alumina levels stably and reliably. The specific challenges associated with each type of switch are outlined in the following table:
Application of Different Level Switches in the Alumina Industry
| Type | Common Problems |
|---|---|
| Rotary Paddle Switch | 1. Paddle deformation due to material impact |
| 2. Bending of the lengthening tube | |
| 3. Frequent false alarms | |
| 4. Short working life | |
| RF Admittance Level Switch | 1. Probe deformation due to material impact |
| 2. Frequent false alarms | |
| 3. Inaccurate measurement | |
| Tuning Fork Level Switch | 1. Material buildup between forks |
| 2. Fork deformation due to material impact | |
| 3. Frequent false alarms | |
| Single Rod Level Switch | 1. Probe bending |
| 2. Frequent false alarms | |
| Photoelectric Switch | Inapplicable in strong magnetic fields |
Recently, a large alumina group in Shandong Province enlisted the help of the Institution of Petroleum and Chemical Industry to solve the level measurement problem. Through recommendations from another alumina manufacturer, the institution learned of the excellent performance and reputation of the Jiwei Tube-11 vibrating rod level switch.
After several rounds of comprehensive comparisons among different level switches from various manufacturers, the group contacted Jiwei. Following a series of experiments, Jiwei’s technical engineers determined the optimal installation position.
Since then, all Tube-11 vibrating rod level switches have been successfully implemented in the alumina project. These switches operate effectively even in the presence of strong magnetic fields or high ambient temperatures.
