Herausforderung im Tunnel, heutige Sicherheitsaspekte

Herausforderung im Tunnel, heutige Sicherheitsaspekte

Seit dem Jahre 2010 wird in die technische Aufrüstung der Schweizer Nationalstrassen-Tunnels investiert um diese auf den heutigen, Europaweit geltenden Sicherheitsstandard zu bringen. Dazu werden bis ins Jahr 2022 rund 1,2 Milliarden Franken investiert. Nebst der Verbesserung der Signalisation stehen vor allem Anpassungen der Tunnellüftung und Fluchtwege im Zentrum zur Erhöhung der Sicherheit im Ereignisfall an.

In einer weiteren Auflage des Tunnelsymposiums der Firma SIGRIST-PHOTOMETER AG möchten wir dem interessierten Fachpublikum eine Plattform bieten, sich durch die angebotenen Vorträge und Expertendiskussionen ein Bild über die Herausforderungen  bei der Umsetzung dieser Ziele unter den heutigen Sicherheitsaspekten zu machen.

Dabei sollen auch die bereits gemachten Erfahrungen am Beispiel der Umfahrung Lungern aufgezeigt werden.

In den 60-er Jahren wurde die Nationalstrasse N13 mitten durch das Dorf Roveredo gebaut. Mit einer Umfahrung, welche u.a. den 2.4 Km langen Tunnel San Fedele beinhaltet, wird diese Bausünde bis im Jahre 2016 behoben sein. Die Führung am Nachmittag vor Ort informiert über dieses interessante Projekt und den aktuellen Ausführungsstand. 

This Event will be held only in German.

Absorption Measuring Instrument in-line

The ColorPlus measures the colour/absorbance online at up to three different wavelengths in the UV and visible range, also combined. Turbidity can be compensated at the same time by selecting an appropriate wavelength. The modular design of the instrument enables to cover various applications by selecting the most suitable measuring cell. In many cases, a standard housing like e.g. Varivent® is used. Alternatively, custom-specific flow cells in different materials and designs are available. For inspecting the instrument, checking units on the basis of reference filters can easily be inserted. Operation is done intuitive using the intelligent control system SICON via touch screen technology and colour display. Values, graphs, alarm and status messages can be presented. An internal data logger allows recalling and displaying measured data from the last 32 days. A variety of analogue and digital interfaces allows smooth system integration and control.

Absorption Measuring Instrument bypass

The ColorPlus measures the colour/absorbance online at up to three different wavelengths. The bypass measuring cell has been specifically designed for applications within the water industry. Depending on the configuration it allows measuring DOC (UV absorption) and colour (Hazen) simultaneously and to compensate turbidity. Soiling of the flow cell is measured by means of a compensation glass in the interior of the flow cell. The effect of cell soiling is greatly reduced internally; constant and precise measured values are guaranteed. The user is alerted if the cell has to be cleaned. The cover of the flow cell can be opened without tools and allows simple access for cleaning the flow cell. For inspecting the instrument, checking units on the basis of reference filters can easily be inserted. Operation is done intuitive using the intelligent control system SICON via touch screen technology and colour display. Values, graphs, alarm and status messages can be presented. An internal data logger allows recalling and displaying measured data from the last 32 days. A variety of analogue and digital interfaces allows smooth system integration and control.

Ozone meter for gases

The Ozone meter for gases measures the ozone concentration according to standard DIN 19627 and the IOA (International Ozone Association) at a wavelength of 254nm. According to these standards, the extinction coefficient is 3024 l/mol cm. Therefore, the ozone measurement can be regarded as an absolute measurement requiring no calibration with ozone. Special measuring cells with different path-lengths cover measuring ranges for low as well as high concentrations. The concentration readings (e.g. in g/m3) are valid for the pressures and temperatures prevailing during measurement. For the conversion to standard conditions, an external pressure and temperature sensor can be connected to the operating unit, die calculation is then automatically done within the instrument. For inspecting the instrument, checking units on the basis of reference filters can easily be inserted. Operation is done intuitive using the intelligent control system SICON via touch screen technology and colour display. Values, graphs, alarm and status messages can be presented. An internal data logger allows recalling and displaying measured data from the last 32 days. A variety of analogue and digital interfaces allows smooth system integration and control.

Ozone Meter for ultra pure water

The Ozone meter for gases measures the ozone concentration according to standard DIN 19627 and the IOA (International Ozone Association) at a wavelength of 254nm. According to these standards, the extinction coefficient is 3024 l/mol cm. Therefore, the ozone measurement can be regarded as an absolute measurement requiring no calibration with ozone. The special measuring cell with a path-length of 100mm allows measuring ozone in ultra pure water in the ppb range. For inspecting the instrument, checking units on the basis of reference filters can easily be inserted. Operation is done intuitive using the intelligent control system SICON via touch screen technology and colour display. Values, graphs, alarm and status messages can be presented. An internal data logger allows recalling and displaying measured data from the last 32 days. A variety of analogue and digital interfaces allows smooth system integration and control.
