This filter is used to obtain the best response time in an environment close to a main road.

The sensor itself is protected from foul weather by a weatherproof casing. It is also protected against direct, indirect and distributed radiation. This protection is designed so that the temperature distribution is uniform internally and very close to the temperature of the outside air. Natural ventilation guarantees a very rapid response time for measurements.

Pavement Sensors

ARCTIS
BOSO II
BOSO III

Features

  • Freezing point detection by artificial cooling
  • Freezing point detection independent of the thawing agent type
  • Preventive alarms : risk of slippery pavement
  • Alarms : slippery pavement (black ice, frost, ice, freezing snow)
  • Minimum height (41.5 mm) for an easy installation in the pavement
  • Optionally available with housing

The patented ARCTIS (Active Road / Runway Condition Temperature of Ice Formation Sensor) sensor is used as a complement to the passive BoPAS or BOSO sensor. The ARCTIS sensor surface is submitted to cooling and heating cycles generated by a Peltier element.

A PT100 temperature sensor placed close to the sensor surface allows to detect the freezing point of an aqueous solution. The freezing point can be given until 15°C below the pavement temperature.

This active technology provides a reliable information about ice forming conditions on road surface independently of the kind of de-icing agent engaged  The cycles are used to detect any risk or presence of black ice, frost, ice or freezing snow on the pavement.

The sensor can be supplied with a housing for special applications (airports, etc.).

Features

  • Road surface temperature measurement.
  • Active detection of freezing point within 2°C below current pavement temperature.
  • Pavement condition : dry, moist, wet, black ice, frost.
  • Salt factor on the pavement (salt concentration).
  • Pavement status alarms (calculated).
  • Excellent resistance to mechanical stress and chemical agents.

The active BOSO II (BOden SOnde) has been developed to be installed in the pavement. It measures the road surface temperature by means of a PT100 sensor, as well as the electrical properties of the aqueous solution covering the pavement. These parameters allows the evaluation of the salt concentration of this solution.

Besides, the BOSO II sensor is equipped with an active element allowing to cool down a part of the sensor surface by 2°C below the current pavement temperature.

The creation of ice on this cooled area allows to detect an icing danger with great accuracy, independently from the type of thawing agent used, and especially before it happens on the pavement.

This sensor can be used jointly with the type pavement sensor ARCTIS (which effectively measures the freezing point temperature), allowing then to determine accurately the remaining factor of salt on the pavement.

Features

  • Road surface temperature measurement.
  • Thickness measurement of the aqueous solution present over the sensor.
  • Active detection of freezing point within 2°C below current pavement temperature.
  • Pavement condition : dry, moist, wet, black ice, frost.
  • Salt factor on the pavement (salt concentration).
  • Freezing point temperature (calculated).
  • Pavement status alarms (calculated).
  • Excellent resistance to mechanical stress and chemical agents.

The active BOSO III (BOden SOnde) has been developed to be installed in the pavement. It measures the road surface temperature by means of a PT100 sensor, as well as the thickness and electrical properties of the aqueous solution covering the pavement. These three parameters allow for the calculation of the salt concentration, and hence the freezing point temperature of the aqueous solution.

Besides, the BOSO III sensor is equipped with an active element allowing to cool down a part of the sensor’s surface by 2°C below the current pavement temperature.

The creation of ice on this cooled area allows to detect an icing danger with great accuracy, independently from the type of thawing agent used, and moreover before it happens on the pavement.

This sensor can be used jointly with the ARCTIS type pavement sensor (which effectively measures the freezing point temperature), thus allowing to accurately determine the remaining quantity of salt on the pavement.

Meteorological Sensors

NI / SH

The NI/SH Precipitation Sensor is characterised by a reliable optical system which detects rain and snow at 3 grades of intensity. It consists of 4 light boxes which are mounted vertically and opposite each other on a horizontal surface. Each light box comprises an infrared transmitter which is installed in front of a receiver unit. The alignment of the light boxes can also prevent problems with dazzle from an external light source (the sun or street lighting). In addition, the sensor is equipped with an automatic dirt detector and an integral instrument for measuring the ambient temperature. A heating element mounted on each transceiver prevents the formation of condensation or hoar frost. The reliable and robust construction ensures a long service life.

PWS

The PWS (Present Weather Sensor) is a compact and highly sensitive weather sensor which uses optical backscatter technology to analyse the water particles in the air. As a result, it is able to measure all kinds of precipitation, including rain, show or sleet, as well as the range of vision (reduction of visibility due to fog and precipitation). Thanks to its compact construction, the PWS consumes the minimum amount of energy in order to keep the optics dry. The optics are shielded from direct daylight and rain by a protective cover. In this way, the lenses are kept clean and only the minimum of maintenance is required. This high-quality product is also characterised by its ease of installation and its long-term reliability. The measured data are exported via the digital interface for further use and analysis.

RF / TL

The RF/TL sensor measures the relative humidity and the relative temperature, using an integrated electronic unit and the capacitive principle. With the aid of the integral weather protection system with independent ventilation, it is possible to accelerate the removal of condensed water from the measuring head.

WG

The WG (anemometer) sensor is designed to measure wind speed. The lightweight structure is equipped with high-precision sensors and incorporates an integral, electronically-controlled heater in order to prevent the moving parts from freezing and becoming immobilised. This product complies with EC Standards.

WR

The WR (wind direction) sensor is designed to measure wind direction. The lightweight structure is equipped with high-precision sensors and incorporates an integral, electronically-controlled heater in order to prevent the moving parts from freezing and becoming immobilised. This product complies with EC Standards.

Pyranometer

The PYRANOMETER measures the total solar radiation on a flat or sloping surface by means of adjustable feet. The measuring is based on the principle of the thermocouple. The measuring instrument comprises 64 thermocouples which are linked in series. The sensor detects the radiation occurring under the two concentric glass domes, which ensures excellent long-term stability of measurement, as well as a high degree of measurement linearity.

SHM

The Snow Depth Meter measures the actual depth of snow from 0 to 1,000 mm, based on the principle of optical reflection. At regular intervals, the optoelectronic detector is lowered until it is just clear of the surface of the snow. By means of repeated raising/lowering operations, a high level of accuracy is ensured when measuring all types of snow.
