SW-11 Magnetic Switch is qualified with SIL2 / SIL3 Functional Safety Assessment, as well as certified for both Intrinsic Safety (Ex ia IIC T6 Ga) and Flameproof Enclosure (Ex d IIC T6 Gb) explosion protection.

SW-21 has been approved for both Explosion-proof Certifications (Flameproof Enclosure: Ex d IIC T6 Gb and Intrinsic safety: Ex ia IIC T6 Ga). Jiwei holds a utility patent (NO. 201821348285.8) on SW-21.

We offer two types of indicators for Ingress Protection rating IP65 and IP66/67 respectively. Designed with broader panel and greatly increases the visual distance and viewing angle.

In Uson series Ultrasonic Level Transmitters, microprocessor program control technology and intelligent signal processing technology are employed to provide highly efficient and accurate measurements.

Uson-11 provides reliable level detection in large water tanks/pools, trenches, storage tanks, and vessels. With a non-contact sensor, it is widely used in a variety of continuous level measurement applications, such as sewage treatment, chemical industry, coal-fired power plant and marine transportation, etc.

Uson-21 Ex Ultrasonic Level Transmitter is designed with a flameproof enclosure. It is certified for Flameproof Enclosure (Ex d II C T6 Gb) explosion protection by the China National Quality Supervision and Test Centre for Explosion Protected Electrical Products.

The transducer and transmitter of Uson-31 Ultrasonic Level Transducer can be installed separately. Design for real-time monitor of liquid level measurements, with high precision, reliable performance, durable life, convenient installation and free maintenance.

In Float-11 series products, high quality plastic reed switches are assembled. Material for wetted parts can be selected from 304, 316L, and coating material ECTFE/PTFE for highly corrosive liquid.

Float-11A Standard Float Level Indicator is made of 304 or 316L stainless steel, providing high-accuracy, continuous level detection for almost all liquid media.

Float-11P Coated Float Level Indicator is coated with unique coating technique to make sure the float slides up and down smoothly along the guide tube.
