The reflector is mounted at a distance of 10 meters from the transmitter/receiver unit. The visibility is measured using the autocollimation method. Here, the light emitted by the transmitter in the transmitter/receiver unit is reflected via the reflector to the receiver, thereby forming the measurement path (20 m). The light, which is attenuated by the dust particles, diesel soot, etc. in the tunnel atmosphere, is recorded by the receiver in the transmitter/receiver unit. This raw value is processed and converted to a measurement value in the evaluation unit. The VICOTEC 410 compensates for any factors that can falsify the measurement, such as contamination or the long-term drifts of device components /09-02 SICK AG Anayzers & Process Instrumentation Germany All rights reserved 7

8 VICOTEC 410 Introduction Product Information Measuring Principle CO Concentration The principle for measuring the CO concentration is based on the wavelength-specific absorption of infrared light (negative gas filter correlation) by carbon monoxide (CO). In the wavelength range from 4.5 to 4.9 µm, CO has an absorption spectrum that comprises a variety of spike-like absorption lines. The shape and position of the absorption spectrum is characteristic of carbon monoxide.

All preparatory work must be completed by this time. 12 SICK AG Environmental Monitoring Germany All rights reserved /

13 VICOTEC Preparations for Mounting the Devices Arrangement of the Measuring Points in the Tunnel The number and distribution of the measuring points must be suitable for the type of ventilation system used. Further details will depend on the Tunnel profile type Routing Type of ventilation system Number and arrangement of the fans Local regulations The selected measuring points largely depend on the following criteria: With half and cross-ventilation, an even distribution across the length of the tunnel is recommended, with at least 2 measuring points per ventilation section. In the case of a main tunnel with traffic in more than one direction, opposing traffic cannot be ruled out completely. According to the Federal German Guidelines for Equipping and Operating Road Tunnels, RABT, therefore, tunnels with longitudinal ventilation must contain at least 3 measuring points one at a distance of approx. 150 m from each portal, and at least one at the center of the tunnel. If there is a risk of fog intake in the tunnel, fog sensors must be provided at a maximum distance of 10 m from the tunnel portal. The fog effect can intensify in the main tunnel, since dust particles act as further condensation particles. The fog droplets increase the turbidity caused by dust particles. Thanks to the use of fog sensors, fog is detected immediately. As a result, the ventilation control system can prevent fog intake. In the case of bends in the road, the measuring beam between the individual sensors must not be interrupted by the tunnel wall, fittings, or crossing vehicles. Note Additional fog sensors Fog usually penetrates the tunnel up to a distance of 150 m. At points at which this effect cannot be ignored, we recommend the installation of additional fog sensors in the vicinity of the tunnel portals. Fog sensors help to prevent fog intake. Effective fog correction software is available for configurations using a fog sensor pair at the tunnel portal. This software contains a program for detecting fog in the tunnel. The fan regulation system can be controlled in such a way that fog intake is prevented. Since conditions can vary from tunnel to tunnel, the fog correction software can be parameterized to suit the tunnel in question. The parameter settings must be defined in conjunction with SICK during the project planning stage Arrangement of the sensors in a cross-section profile In general, the particle concentration in a road tunnel is distributed very evenly across the profile cross section. Traffic and longitudinal flows caused by natural ventilation, as well as the piston effect of the vehicles in main tunnels for separate directions, cause the inside air in the tunnel to be mixed rapidly. This effect is increased by the eddy currents behind the vehicles. Since the air is mixed well, the height is not an important criterion. The devices are generally installed at a height between 3.5 and 4.5 meters / SICK AG Environmental Monitoring Germany All rights reserved 13

14 VICOTEC SICK AG Environmental Monitoring Germany All rights reserved / Fig. 2.1 Installation height of the VICOTEC 410 sensor The mounting location for the sensor pairs should be selected primarily on the basis of the following criteria: Ensure that the sensors are mounted at a safe distance from the traffic area. Note See also section 1 of the Federal German Guidelines for Equipping and Operating Road Tunnels RABT. Ensure that access is provided for maintenance and monitoring. Wherever possible, mount the sensors in a protected niche. The mounting location should not be within the range of tunnel cleaning services. To ensure that the measurement value reflects the actual concentration, the sensors must not be located within the immediate proximity of the ventilators or fresh-air flow of an extractor fan. The measurement beam between the sensors must not be impeded by fittings or crossing vehicles. The distance between the left sensor and right sensor is 10 meters. Plan sufficient clearance for removing the housing cover. Installation options: Installation of both sensors in a wall niche (recommended). Installation of both sensors on a wall above the shoulder. Requires safety precautions for maintenance requirements if space is at a premium. If only limited space is available, both sensors can be attached to the tunnel ceiling. Generally requires safety precautions while maintenance work is being carried out. Note The measurement values initially remain constant when the light beams are interrupted. If the interruption exceeds the T 90 time (time required to reach 90 % of the measurement value), a malfunction message is output on the evaluation unit. VICOTEC-Sensor 3,5 4,5 m m VICOTEC sensor

15 VICOTEC Attaching the mounting consoles The mounting consoles consist of two parts: The wall bracket, which is mounted directly on the wall The angle attachment, to which the sensor is secured Preparation The wall bracket and mounting console are connected with 3 bolts. The mounting console can be pivoted by up to 15º to compensate for any installation inaccuracies. Secure the workplace Provide adequate lighting, electricity, and a lift truck Provide material, for example: securing material, drill, cables, socket spanner set, torque spanner, marking material, measuring tools and gauges, spirit level. ATTENTION Selection criteria: Define measurement path: The specified measurement path should be observed if possible. Record any deviations in the installation log. Choose the securing material: The tunnel atmosphere is usually extremely corrosive. Only use high-strength and non-corroding securing material. Choose the angle of inclination: The mounting brackets must be aligned with the same angle of inclination to the tunnel wall. Different angles of inclination in the tunnel profile will make it more difficult to align the sensors. If necessary, mount washers under the wall bracket. Step 1 Step 2 Step 3 Step 4 Step 5 Step-by-step procedure Determine the mounting location for the mounting bracket in accordance with the project planning specifications. See mounting hole diagram (Fig. 2.2 Mounting hole drawing and dimensions of mounting console, page 16): Drill the holes for the wall bracket. Ensure that the holes are suitable for the selected dowels or wall anchoring elements. Position the dowels or wall anchoring elements in accordance with the manufacturer s instructions (concrete walls B25 only). First screw on the brackets temporarily. Align them by means of a visual inspection. Tighten the screws as instructed by the manufacturer, using a torque spanner if necessary. Check whether the brackets are generally aligned and correct them if necessary. Note With inclined or rounded cross-section profiles, the wall plate and mounting bracket can also be mounted at a slight inclination. The mounting brackets for each sensor pair must be level but do not necessarily have to be exactly horizontal. Sufficient clearance must be provided to remove the tube and cover / SICK AG Environmental Monitoring Germany All rights reserved 15

17 VICOTEC Fog correction with the VICOTEC 410 According to the RABT, fog intake by the ventilation system in the tunnel must be avoided. For this purpose, the turbidity caused by fog within the tunnel must be measured by a fog sensor. The VICOTEC 410 from the SICK AG allows you to install: A VICOTEC 411 sensor pair in the direct vicinity of the tunnel portal or A VISIC 610 visibility monitor at the tunnel portal. Up to 2 fog measuring points can be integrated in the network on the VICOTEC 410 measuring system. Data transfer takes place via an RS 422 connection.

18 VICOTEC Sensor Pair Arrangement Looking directly at the tunnel wall, the VICOTEC 410 transmitter is located on the left and the VICOTEC 410 receiver on the right. Note With left-hand drive traffic systems, it is more effective to arrange the sensor pair on the right side of the road. Fig. 2.4 Arrangement of the VICOTEC sensor pair Sensor pair arrangement for tunnel bends The VICOTEC sensors can be used in tunnel bends with up to the following curve radii: at the outer wall of the curve: minimum permissible curve radius m at the inner wall of the curve: minimum permissible curve radius 85 m Sensor pair arrangement in tunnels with sound-absorbing walls Suitable mounting bases must be provided by the customer to mount the sensors on a sound-absorbing tunnel wall.
