    Tunnel solutions for the light sensors

    According to the International Committee on Illumination CIE recommendations, luminance should be monitored as the luminance contained within in a conical field of view, subtending an angle of 20º. It is recommended that a luminance photometer is mounted in the tunnel approach road approximately 120 - 200 metres from the portal, depending on the approach speed of the vehicles and their stopping distance. The purpose of monitoring the luminance at the portal is to adjust the level of light intensity inside...

  • Haze Monitoring

    The principle cause of regional and urban haze, or visibility impairment, is light extinction caused by fine particles, sulfates, organic and elemental carbon, nitrates and crustal matter. Particles between 0.1 and one micrometers in size are most effective at scattering light, in addition to being of greatest concern for human health.

    Marine monitoring solutions for the SO2/CO2/NOx monitoring

    Process control of a SO2 scrubber on a ship is a challenge due to wet and corrosive gases. In such environment, extractive gas sampling systems require high levels of maintenance in order to operate correctly. OPSIS monitoring system solves this by using an optical, non-contact, cross-duct technique. A light beam is sent across the duct or stack to be measured, and the captured light is sent through an optical fibre cable to an analyser. The analyser measures SO2, CO2 and NOx concentrations using UV and IR...

  • Seawater Biotoxicity monitoring to protect the coastal waters of Italy

    The recorded death of fish in the river that flows out of the industrial zone of Scarlino has created the need of the installation of a biological alarm system. The decision was made to work with an automatic system, iTOXcontrol created by microLAN-The Netherlands represented in Italy by Ecotox Lds, which uses marine bacteria. The system compares the values of the light emission from these organisms at the entrance and exit of the canal, generating alarms in the presence of toxic substances.

    Instruments and analyzers for outdoor material testing

    Weathering of materials is most often an irreversible process affecting the cosmetic properties or strength of materials. This aging process is mainly driven by UV radiation, Heat and reactive elements in the atmosphere, for example chemical contamination. The plastic fabric of the product can dry and therefore weakened. The solar load can overheat the products and change material properties irreversibly. A common method to test the deterioration of materials is to expose materials to sun light and...

    Fire detection solutions for the oil rigs

    The worse event that can befall on off shore oil rig is fire. The Model 125 is a smoke monitor designed to operate in hazardous areas, especially in oil rig air conditioning and ventilation ducts. The electronics are contained in an explosion proof container rated as EEX de II B T5; the sensing head uses fibre optic cables to transmit the near infra-red light to a reflector where it is returned to another fibre optic cable. The light level is then monitored by a photo-electric cell. The Model 125 gives an...

    Instruments and analyzers for measuring spectral irradiance

    Spectral irradiance is the irradiance of a surface per unit frequency or wavelength. spectral irradiance of a wavelength spectrum is measured per watts per square metre per nanometre (W·m−2·nm−1). Spectroradiometers are devices designed to measure the spectral power distribution of a source. From the spectral power distribution, the radiometric, photometric, and colorimetric quantities of light can be determined in order to measure, characterize, and...

  • Water quality monitoring for pulp & paper industry

    Pulp and paper waste streams are exceptionally well suited for spectral analysis due to the high concentration of UV/Vis light absorbing organics in their process water and waste streams. Continuous monitoring of the organic load by means of COD/BOD correlations will help ensure the treatment process is carried out in the most efficient way possible by optimizing aeration rates and nutrient dosing while also making sure that all the regulatory goals are met.

  • Dust monitoring of exhaust gases from manufacturing processes

    DynOptic dust monitors use the innovative Dynamic Detection Principle (DDP) to measure dust and particulate within exhaust gases from various manufacturing processes. DDP, or optical scintillation as it sometimes referred to, measures the dynamic fluctuation in light transmission as dust particles move through a light beam. This dynamic fluctuation derives from temporal distributions of the dust particles which attenuate the light beam. The more dust present in the exhaust, the greater the amplitude of these...

    Ambient air quality monitoring solutions for remote sensing of ship emissions

    New regulation forces ships to lower the emissions of SO2. Ships travelling in SECA areas has to either run on low sulphur fuel, or install SO2 scrubbers. To measure the SO2 emissions from a ship is not an easy task. OPSIS provides the Port Authorities with a unique measurement principle where the emissions from the ship is measured remotely. Light is passing the emissions and by analyzing the light, concentrations of SO2 can be measured.
