Frequently Asked Questions

What is the difference between a tuning fork and vibrating rod switch?

Tuning fork switches are ideal for liquids with low density (≥0.5 g/cm³), while vibrating rod models are designed for bulk solids and interfaces, detecting materials as light as 0.008 g/cm³.

Are your radar meters suitable for dusty environments?

Yes, our 80GHz radar level meters use focused beams and AI-enhanced signal processing to maintain accuracy even in high-dust silos and tanks.

Do you offer explosion-proof models?

Yes, we offer ATEX, IECEx, and SIL-certified explosion-proof level switches and transmitters for hazardous areas in oil & gas, chemical, and mining industries.

Can I get a sanitary version for food applications?

Absolutely. Our sanitary level switches feature 3-A certification, smooth surfaces, and CIP compatibility for food, beverage, and pharmaceutical use.
