Ring-11 Liquid Level Switch with Stainless Steel Housing

Piezoelectric devices are used to drive vibration and detect changes. When the resonant vibration fork contacts the application medium, its vibration frequency decreases significantly. This reduction in frequency is reflected in the output signal from the piezoelectric detection device. An integrated circuit then analyzes this signal and generates a switch signal in response.

●　Enhanced cleanability and safety with a crevice-free, polished, and hygienic design.

●　The most robust and reliable solution for measuring liquid levels in harsh environments, including high temperatures, strong abrasion, and severe corrosion.

●　Available with stainless steel housings in both SS304 and SS316.

●　Provides safe and reliable performance to meet the complex needs of a wide range of process applications.

●　With a 40mm fork length, specially designed for pipelines and confined spaces.

●　High sensitivity due to the precisely pre-adjusted harmonic resonant frequency of the fork. The lowest detectable medium density is as low as 0.5g/cm³.

●　Strong anti-interference function, unaffected by foam, bubbles, viscosity, oscillation, and other liquid characteristics.

●　Hastelloy C-22 material available as an option, providing excellent resistance to fluid corrosion and erosion in high-temperature applications, setting the standard in China.

●　Industry-leading performance for high-temperature applications, with a process temperature capability of up to 250°C.

●　Four optional outputs available: relay, two-wire, NAMUR, and transistor.

●　SIL2/SIL3 certifications in accordance with IEC 61508 international standards. Intrinsically safe and explosion-proof certificates enable operation in hazardous areas.

●　CE certification for compliance with European safety standards.

●　For the automation, mining, shipbuilding, chemical, pharmaceutical industries, as well as the stringent requirements of sanitary applications.
