Ring-11 Liquid Level Switch has four optional outputs: relay output, two-wire system, NAMUR and transistor. It has also Passed SIL2 / SIL3 Functional Safety Assessment, as well as certified for both Intrinsic Safety and Flameproof Enclosure explosion protection.

After test trial, the client replaced all the original liquid level switches to Jiwei Ring-11 Intrinsically Safe Tuning Fork Liquid Level Switch with NAMUR Output.

Tube-11 Vibrating Rod Level Switch is designed with double vibrating tubes, which prevents bulk material from getting stuck or jammed.

　　After detailed communication with the client, Jiwei engineer recommended Tube-11 Vibrating Level Switch due to the large proportion of alumina particles and the strong magnetic field.

The user decided to replace all imported Siemens admittance level switches to Jiwei Cape-11R Rope Type Admittance Level Switches to measure the level of coal silos in the power plant.

For Ring-11, the coating and the fork body are perfectly combined without falling off and cracking, so it has the characteristics of stronger corrosion resistance and longer service life.

Through the test, the specially adjusted Tube-11 is not able to switch alarm in water, but when VDF monomer is touched, the alarm signal appears.

According to the working principle of rotary paddle switch, the quality of the micro motor has a crucial impact on the stability and reliability.

According to the requirements and the characteristics of field conditions, Jiwei engineer recommends to apply Uson-11 Ultrasonic Level Transmitter with a measuring range of 15m.

The client reported that all tuning fork liquid level switches have been working stably and reliably without false alarm, which effectively guarantees the production progress.
