Tunnel Sensors - VIPA MkII - Visibility Monitor for Tunnels

by Tunnel Sensors Limited

The VIPA MkII tunnel monitor makes a visible opacity measurement to determine the visibility within the tunnel. These measurements can be used as part of an air quality management system for ventilation control and/or secondary smoke detection within a traffic tunnel, rail tunnel or other confined space.

Tunnel Sensors - VCOM - CO and Visibility Monitor for Tunnels

by Tunnel Sensors Limited

The VCOM tunnel monitor measures the concentration of carbon monoxide (CO) in tunnel atmospheres and makes a visible opacity measurement to determine the visibility within the tunnel. These measurements can be used as part of an air quality management system for ventilation control and/or secondary smoke detection within a traffic tunnel or other ...

Tunnel Sensors - VNOX - NO2 and Visibility Monitor for Tunnels

by Tunnel Sensors Limited

The VNOX tunnel monitor uses differential optical absorption to measure nitrogen dioxide (NO2) in tunnel atmospheres and makes a visible opacity measurement to determine the visibility within the tunnel. These measurements can be used as part of an air quality management system for ventilation control and/or secondary smoke detection within a ...

VICONOX - Visibility Monitor for Tunnels

by Tunnel Sensors Limited

The VICONOX tunnel monitor is a single sensor solution for measuring NO2, NO, CO, visibility and temperature within a traffic tunnel, rail tunnel or other confined space. These measurements can be used as part of an air quality management system for ventilation control and/or secondary smoke detection.

OSi - WSS-300-DS - Tunnel Wind Speed And Smoke Sensor

by Optical Scientific Inc. (OSi)

For drift-free air flow measurements across traffic tunnels; WSS-300-DS calculates true average speed of air movement, and detects smoke. The sensor is equipped with Automatic Gain Control (AGC) to compensate for  opacity variations caused by particulates, smoke, or suspended moisture. The WSS-300-DS uses patented optical scintillation ...

TunnelCraft - 4 - Air Flow Monitor (AFM)

by Codel International Ltd

The Air Flow Monitor (AFM) uses ultrasonic technology to measure air velocity. A single transmitter and an array of four receivers are contained in the measuring head. Air velocity and direction are calculated from measurements of the phase shifts from the ultrasonic signals at the receivers. The sensor is compact, contains no moving components, ...
