CODEL tunnel sensors are designed exclusively for road tunnel applications. Our range of sensors provide all the essential measurements necessary to monitor and control the tunnel atmosphere.
Available as stand-alone sensors or integrated into a network system, CODEL’s tunnel sensors are installed in over 350 road and rail tunnels worldwide.
TunnelTech 100 Series - Visibility
CODEL’s The TunnelTech 100 Series Sensors are an essential part of any road or rail tunnel safety system. Firstly, it monitors the Visibilty within the tunnel and ensures that the tunnel ventilation system
provides sufficient clean air for drivers to clearly see the road ahead.
TunnelTech 200 Series - Air Quality
The TunnelTech 200 Series Air Quality Monitors are is an essential part of any road or rail tunnel safety system. Firstly, it monitors the atmosphere within the tunnel and ensures that the tunnel ventilation system provides sufficient clean air to protect tunnel users health and for drivers to clearly see the road ahead.
TunnelTech 300 Series - Air Flow
The TunnelTech 300 Series Air Flow Monitors (AFM) are CODEL’s industry proven tunnel air flow monitors that combine the reliability of ultrasonic technology and delivers superb accuracy and reliability at a very competitive price.
TunnelTech 500/700 Series - ECELL Range
The TunnelTech 500/700 Series, is an essential part of any road or rail tunnel safety system. The 500 & 700 use electrochemical cell technology to determine CO, NO & NO2 concentrations. As there are no moving parts, reliability levels are very high and maintenance requirements are low.
TunnelTech 600 Series - Light Sensors
The TunnelTech 600 series light monitors are CODEL’s industry proven llumiance and illuminance monitors for detecting light both inside and at the entrance of the tunnel.
TunnelTech 800 Series - Cross Tunnel Flow Monitors
The TunnelTech 801 has been specifically designed for road, rail and civil tunnel and ventilation shaft applications and represents the latest in compact ultrasonic sensor-head design.
