Design & Functionality
The RFLS-35 sensor uses high-frequency signal analysis to detect changes in the dielectric properties of surrounding media. This allows reliable measurement even when process materials leave conductive coatings or foam on the sensing electrode. The rugged stainless-steel body ensures durability in harsh industrial environments, while specialized electrode materials such as PEEK or PTFE provide high resistance to aggressive chemicals.
Direct installation into tanks, pipes, vessels, or containers simplifies integration into existing systems. The compact design allows the sensor to operate in confined spaces without compromising measurement accuracy.
Total Crossed Beams
The high-frequency detection principle enables accurate recognition of the medium level by analyzing electromagnetic interaction with the process material. This advanced sensing method improves detection reliability and eliminates false switching caused by foam layers, deposits, or residues.
Beam Pitch Options
Different electrode and sealing configurations allow the sensor to adapt to a wide range of process media including oils, chemicals, fuels, and aggressive liquids. Threaded or hygienic process connections ensure compatibility with multiple industrial installations.
Intrinsic Synchronism
The integrated media recognition feature allows the sensor to differentiate between materials with different dielectric properties. This selective detection capability ensures the device reacts only to the configured medium, preventing unwanted switching caused by other substances.
Operational Advantages
The RFLS-35 sensor delivers reliable performance for industrial level monitoring while minimizing maintenance requirements. Its resistance to buildup, advanced sensing technology, and flexible configuration make it suitable for demanding process environments.
