  * Scattered light visibility sensor with dual beam method
  * Dust concentration measurement with gravimetric calibration
  * Optional up to 3 electrochemical gas sensor modules (CO, NO, NO<sub>2</sub>, SO<sub>2</sub>)
  * Installation in-situ (in the tunnel’s driving area) or with suction line up to 10 m
  * Active extraction of sample air by integrated fan
  * Integrated purge air system
  * Optional sample heater to eliminate fog from measurement
  * Stainless steel housing 1.4404 (AISI 316L)
  * IP rating IP69
  * Connection to tunnel control system by
    * MODBUS RTU (RS-485)
    * MODBUS/TCP (Ethernet)
    * Analogue and relay outputs
    * JSON Web service (Ethernet)
  * Integrated web server for visualisation, configuration, data logging, remote maintenance((only Standard and Smart variant))
  * Optional smart/HUB IoT operating and control unit with touch display
  * Plug & play operation

===== System =====


  * smart/AQM sensor to be mounted either
    * in-situ (directly in the tunnel’s driving area) or 
    * extractive in a niche, cross-cut, etc.
  * Terminal box with 24 VDC power supply for connection of supply and signal cables
  * System cable with quick connectors between sensor and terminal box for quick and easy sensor exchange
  * Optional smart/HUB with touch display


<newcolumn>


===== Operation =====

Visibility and gas monitoring during normal operation is used to control the tunnel ventilation at normal operation. If and with how much power artificial ventilation by jet fans is operated depends on the measured visibility and gas concentration.


Visibility is expressed by the extinction coefficient, which describes the light attenuation caused by particles in the air. The sensor extracts air from the tunnel by an integrated fan and feeds it into the measuring cell which detects the intensity of light scattered by this sample, sets it into relation with the light passing through and calculates the extinction coefficient.


Optional electrochemical gas sensor cells induce currents proportional to the prevailing gas concentration. With these currents and the measured temperature, the gas sensor modules calculate the gas concentrations.


===== Advantanges =====

  * Specifically designed for application in tunnels
  * Single sensor instead of transmitter/receiver pair requiring exact alignment
  * Effective fog elimination by optional heater
  * Easy recalibration by calibration plug
  * Internally generated purge air keeps optics clean and prevents long-term drift
  * Low maintenance requirements, stable, accurate
  * Smart IoT enabled solution from sensor over hub to asset management
  * Condition monitoring
  * Remote maintenance
  * Flexible integration into tunnel control system
  * Pre-calibrated gas sensor modules for easy exchange

===== Application =====



~~SNIPPET_O1715927446~~en:snippets:datasheet:application~~
Tunnels are important infrastructure elements in road networks and facilitate the connection of regions. 

Environmental conditions in tunnels are influenced by fog, particles and emissions and need to be monitored to protect people on their passage through the tunnel from danger and impacts on their health. Accidents in tunnels, and particularly fires, can have dramatic consequences and can prove extremely costly in terms of human life, increased congestion, pollution and repair costs. At every time people in the tunnel need to be supplied with breathable air and sufficient visibility.

Since 1990 JES Elektrotechnik GmbH develops, installs and maintains systems to monitor air characteristics and lighting conditions in tunnels. Our systems are robust, durable and resistant against the corrosive atmosphere in a tunnel. They operate reliably and have a high accuracy in measurement. 

All systems fulfil the requirements of the EC guideline 2004/54/EC (Minimum safety requirements for tunnels in the trans-European road network) and the more detailed national guidelines and provisions:

  * Austria: RVS 09.02 Tunnelausrüstung
  * Germany: RABT Richtlinien für die Ausstattung und den Betrieb von Straßentunneln
  * Switzerland: ASTRA Richtlinien und Fachhandbuch Betriebs- und Sicherheitsausrüstungen (BSA)

Our range of products for tunnel covers systems for monitoring of

  * Visibility (extractive or in-situ) 
  * Toxic gases like CO, NO, NO2 (extractive or in-situ)
  * Air velocity, direction and temperature
  * Luminance (access, threshold and interior zone)
  * Illuminance
