Tunnel environment

A tunnel measurement system is a versatile tool for gathering critical data within various types of tunnels and confined spaces. Our systems enable the measurement of parameters like NO2, NO, (NOx), CO, visibility, and temperature, either independently or in combinations, making it applicable to road traffic tunnels, rail tunnels, and similar environments. These measurements play a crucial role in supporting air quality management systems for tasks such as controlling ventilation and detecting secondary smoke.

Our systems are specifically designed for the challenging conditions of tunnels, the measurement system features a durable, high-quality stainless steel enclosure with an IP67 rating. Its wall-mounted alignment bracketry, quick-release sensor heads, and easy-to-use quick-lock cable connections simplify the installation process and facilitate future servicing.

Additionally, the intelligent sensor heads of this measurement system offer standard connectivity options, including RS485 (Modbus RTU), Digital Relays, and Analog Outputs, making it easy to integrate with PLC/SCADA systems for efficient data monitoring and management.

  1. Safety: Tunnel environments often present unique challenges, including air quality issues, temperature variations, and potential fire hazards. Proper monitoring is crucial for ensuring the safety of both travelers and workers.
  2. Air Quality Management: Tunnels can accumulate pollutants and exhaust fumes from vehicles, which can have adverse health effects. Monitoring air quality parameters like NO2 and CO is essential for maintaining acceptable air quality levels.
  3. Ventilation Control: Effective ventilation systems are vital to control pollutants and maintain a comfortable environment inside tunnels. Monitoring temperature and visibility helps optimize ventilation strategies.
  4. Emergency Response: In the event of accidents or emergencies in tunnels, real-time data from tunnel monitoring systems can aid emergency responders in making informed decisions and safeguarding lives.
  5. Regulatory Compliance: Many tunnels are subject to regulatory requirements and standards for air quality and safety. Accurate monitoring ensures compliance and avoids potential legal and environmental consequences.
