LUMIOS MkII - Tunnel Luminance Photometer

by Tunnel Sensors Limited     based in Crowfield, UNITED KINGDOM

The LUMIOS MkIII measures the level of luminance, or brightness, created by natural light at the tunnel portals to ensure that the visual perception of drivers is maintained, both day and night, by avoiding sudden variations in lighting levels and potential “black hole effect” when entering and exiting a tunnel. The LUMIOS MkIII can ...

VICONOX - Tunnel Monitor

by Tunnel Sensors Limited     based in Crowfield, UNITED KINGDOM

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.

Tunnel Composting

by Ecomaster Atzwanger S.p.A     based in S. Maria la Longa, ITALY

One of the most advanced processes developed by Ecomaster is tunnel composting. Tunnels consist of large enclosed reactors, made of reinforced concrete, with floors equipped with integrated aeration systems. This technology allows better control of the biological process, which is monitored by sensors transmitting the various process variables to ...

DURAG - Model D-R 220T - Visibility Monitor System

by DURAG GmbH     based in Hamburg, GERMANY

Visibility Monitor for road tunnels using optical transmission principle. Sensor for ventilation control system or fire alarm system. Reliable measurement parallel to the tunnel axis.

DURAG - Model D-FL 220T - Ultrasonic Flow Velocity Monitor System

by DURAG GmbH     based in Hamburg, GERMANY

Measuring system for continuous evaluation of flow velocity and flow direction in tunnels. Ultrasonic sensors for tunnel ventilation control system. Reliable measurement across the tunnel profile. Two identical sensors alternately transmit and receive ultrasonic pulses. The system evaluates the transition times dependant on direction and ...

JES - Model LWA-LC - Illuminance Photometer

by JES Elektrotechnik GmbH     based in Hallein, AUSTRIA

Stationary sensor to measure the illuminance. Analogue output 4 - 20 mA corresponding to 0 - xx lx (xx stands for the end of the measuring range that needs to be specified when ordering). Operating voltage 24 VDC. Optionally also available in a heated housing (IP65) with dimensions 300 x 250 x 140 mm (requires 230 VAC supply for heating). Output ...

JES - Model ECS300-T - Electrochemical CO Sensor

by JES Elektrotechnik GmbH     based in Hallein, AUSTRIA

The electrochemical CO sensor is mounted in the tunnel's traffice area, i.e. directly at the sampling point. The sensing element is contained in a shock resistant plastic housing which again is mounted in a stainless steel housing with intake cowl and protection against water ingression. Available either as wall-mounted or flush-mounted box or ...

TunnelCraft - Model III - Air Flow Monitor

by Codel International Ltd     based in Bakewell, UNITED KINGDOM

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, ...
