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.
Overview :
measurement parallel to tunnel axis, continuous measurement
measurement along a distance of 10m, no spot measurement
corrosion resistant against tunnel atmosphere
determination and correction of the pollution of optical surfaces
measuring head and reflector can be exchanged quickly N – no tools required – no re-alignment required
signal transfer – per analog signal and relay outputs – per RS485 Modbus RTU
hermetically sealed housing - no gas diffusion to optics or electronics
dust protection tube prevents contamination of the optics
long maintenance intervals
quick and easy startup with or without PC
Benefit :
Precise visibility monitoring Transmission principle with compensation of pollution of the optical surfaces allows stable and precise measurement of the visibility
Easy system setup and autonomous operation Measuring device does not require an additional operation unit. Measuring devices can be replaced quickly with no tools or re-alignment required
Long Lifetime and extremely low maintenance requirements Use of durable components stand for low maintenance costs and a long Lifetime
Robust Design for a wide range of environmental conditions High-quality, corrosion-free plastic housing and a wide ambient temperature range
Easy connection due to configurable interfaces Connection to tunnel control system either via freely adjustable analogue output, relay or RS-485 Modbus RTU
Field-tested in road-tunnels Long-standing experience in various tunnel applications
