JES - Model LWA-LC - Illuminance Photometer

by JES Elektrotechnik GmbH

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 ...

TunnelCraft - Model 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, ...

Model TMS3000D - Air-flow Measurement System

by Schiltknecht Messtechnik AG

Mechanical ventilation of tunnel systems ensures that exhaust gases and dirt particles are discharged from the tunnel tubes. Ventilation is more efficient and economical when it can be controlled by the air flow in the tunnel tube. TMS3000D measures the flow velocity in longitudinal direction (vz) and flow direction with high precision.

TunnelCraft - Model III - Air Flow Monitor

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, ...

Tunnel Sensors - Model LUMIOS MkII - Tunnel Luminance Photometer

by Tunnel Sensors Limited

The LUMIOS MkII measures the level of luminance, or brightness, created by natural light at the tunnel entrance / exit 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 MkII ...

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

by DURAG GmbH

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

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 ...

TunnelCraft - Model 4 - CO/VIS Air Quality Monitor (AQM)

by Codel International Ltd

The TunnelCraft 4 CO/VIS Air Quality Monitor (AQM) uses infrared light and visible light to measure carbon monoxide and visibility in a single compact instrument. The AQM consists of a transceiver that projects infrared beams to a reflector unit mounted 3m away. The reflected light is received by the transceiver and the specific absorption is ...
