Ring-11 corrosion-resistant level switch is designed for liquid level detection in processes that involve highly corrosive acidic or alkaline media. It is a practical choice for chemical plants and other industrial sites where standard metal wetted parts may not provide enough protection. Because the switch supports different protective coatings, users can choose a suitable configuration according to the corrosion strength of the liquid.
The fork body and process connection can be coated with materials such as ECTFE, PFA, enamel, or other protective layers. This helps the switch resist corrosion and maintain stable operation in aggressive liquid applications. As a result, it is well suited for strong acids, alkalis, chemical intermediates, industrial wastewater, and other demanding process media.
Reliable Tuning Fork Detection in Difficult Conditions
The switch works on the tuning fork resonance principle. Piezoelectric devices drive the fork into vibration and detect changes in its resonant frequency. When liquid touches the fork, the vibration frequency drops. The electronics detect this change and convert it into a switching signal. This design gives the device stable and reliable switching performance across a wide range of liquids.
Ring-11 corrosion-resistant level switch can detect liquids with densities as low as 0.5 g/cmยณ. It also resists interference from foam, bubbles, viscosity, vibration, and other process disturbances. Therefore, it performs well in difficult liquid conditions where stable point level detection is important.
Suitable for High Temperature, High Pressure, and Hazardous Areas
For severe operating conditions, the switch can be equipped with an extension tube and a high-pressure protective gas-tight insulating sleeve. This design helps it perform reliably in applications that combine high temperature, high pressure, and corrosive liquid media. It also helps protect the internal components in demanding process environments.
The device supports multiple output options, including relay, two-wire, NAMUR, and transistor. It also carries SIL2 / SIL3, CCC, CE, and EAC certifications, together with intrinsically safe and explosion-proof approvals. Therefore, it is suitable for safety-critical industrial applications and hazardous areas.
Typical Applications
Ring-11 corrosion-resistant level switch is widely used in acid storage tanks, chemical reactors, raw material vessels, and process kettles that handle strong acids, alkalis, or other aggressive media. It is also suitable for chemical fragrance production, pesticide manufacturing, and industrial systems that require reliable liquid level switching in corrosive and high-temperature environments.
