Tunnel & Industrial Environments

Let's face it: highway tunnels and industrial mines are brutal environments for delicate optics.

They are dark, highly turbulent, and choked with vehicle exhaust and soot. Put a standard sensor in a tunnel, and the lenses are blinded by grime within weeks. The result? False alarms that trigger massive, megawatt jet fans, burning through thousands of dollars in wasted electricity.

Engineered for the underground reality

We designed our tunnel instrumentation assuming it will be neglected, washed with high-pressure hoses, and covered in exhaust.

• Cross-Tunnel Airflow: Single-point wind sensors fail because tunnels have weird edge turbulence. We use crossed-type ultrasonic sensors that shoot sound waves across the entire tunnel span, giving you the true average air velocity.
• Optical Compensation: Our transmissometers don't panic when they get dirty. Built-in compensation algorithms adjust the baseline as soot builds up on the lens, vastly extending your maintenance cycles.
• No More "Black Hole" Effect: Our tunnel entrance luminance meters perfectly mimic the human eye's spectral response, dynamically adjusting portal lighting so drivers aren't blinded when entering or exiting.

We build instruments that operators can trust to run automated ventilation control safely, efficiently, and without false trips.
