Jiwei Rotary Paddle Switches have successfully won the bid in some waste incineration power generation projects.

The user finally selects Flap-11 series magnetic level gauge and Ring-11 tuning fork liquid level switch as the level control solution for high/low alarm after comparison.

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.

According to the suggestion, the client selects Uson-21 Flameproof Ultrasonic Level Transmitter with a measuring range of 10m. So far, all the sensors have been installed and fully operated.

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.

Ring-21 can withstand 150 ℃ high temperature and 40 bar process pressure, and has higher reliability, which fully meets the requirements of steam generator.

Ingress protection rating of Flap-11S Magnetic Level Indicator reaches to IP67 thanks to the special sealing technique used on its display panel.

Jiwei Rotary Paddle Switches have been running smoothly with stable and reliable performance to ensure the normal operation of the waste incineration power plant since they were installed and put into use.

Ring-11 liquid level switch now is widely used in pump protection systems in various industries, its stable and reliable performance are well recognized by users.
