SONIC/Sonic Tunnel Ultrasonic AnemometerIntroduction:

This anemometer is developed specifically for measuring wind speed stably and accurately for a long time even in harsh tunnel environments.

It provides wind speed information necessary for tunnel ventilation and control in case of abnormal events such as fires.

From "zero" m/s.

Start measuring wind speed, no moving parts, and environmental resistance.

Excellent and accurate measurement of axial components in tunnels.

Core technological advantages:

1. No mechanical wear and tear, suitable for complex environments

The product has no moving parts, and the probe is made of corrosion-resistant and pollution resistant alloy material, which can withstand high dust, high humidity, and corrosive gas environments in tunnels for a long time, significantly reducing operation and maintenance costs.

2. Wide range and fast response

The measurement range covers from -60m/s to+60m/s, and can capture both forward and reverse airflow simultaneously; The response time is less than 0.2 seconds, especially suitable for monitoring sudden changes in wind direction under tunnel fire conditions, providing millisecond level data for smoke exhaust system linkage.

3. Anti interference and self heating design

Built in advanced digital signal processing algorithms effectively suppress turbulent airflow and electromagnetic interference of vehicles inside the tunnel. Optional probe self heating function can prevent icing and condensation, ensuring measurement stability in high-altitude or cold winter areas.

4. Multi protocol output and system integration

Standard configuration includes 4-20mA, RS485 (Modbus RTU), and relay output, allowing seamless integration into tunnel PLC monitoring systems or SCADA platforms. Simultaneously providing optional Modbus TCP/IP modules to meet the needs of digital tunnel management.

5. Protection level and easy installation

The whole machine has reached IP67 protection level and supports wall mounted or bracket side wall installation. Equipped with a dedicated installation base and shockproof design, it can resist low-frequency vibrations caused by vehicle traffic.

Typical application scenarios:

Ventilation Control and Energy Efficiency Optimization of Highway/Railway Tunnels

Air flow monitoring and fire linkage smoke exhaust in subway sections

Monitoring of limited space environments such as mine tunnels and underground pipe galleries
