How does the ultrasonic technology in the Sonac 110 work for level detection?

−

The Sonac 110 sends a high-frequency ultrasonic signal across a small gap or along the probe tip. When liquid covers the sensor, it changes the way the sound wave propagates. The device’s electronics detect this change instantly to trigger an alarm, providing accurate on/off level detection without needing any mechanical actuation.

Is the Sonac 110 suitable for use in explosive atmospheres?

Yes. The Sonac 110 is available with versions certified for hazardous areas, including ATEX for European compliance and NEC Class I Div 1 options for North America, ensuring safe use in explosive environments.

What advantages does the Sonac 110 offer compared to mechanical float switches?

The primary benefit is reliability and zero maintenance. Unlike float switches, the Sonac 110 has no moving parts to wear out, stick, or become clogged by viscous liquids or buildup. This makes it far more dependable for long-term level monitoring in challenging industrial media.
