  • 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 fluctuations. DDP instruments calculate the dynamic response, or the ratio of light variation to light intensity, which for particular applications, is proportional to dust concentration and when calibrated against standard reference measurements, this can be presented as a reading in mg/m³.

  • Hydroxyl Number in Polyols (OH#) #3013

    The use of polymeric polyols is commonplace in the manufacturing of polyurethanes and other specialty polymers. The hydroxyl number (OH#) is a measure of the concentration of the hydroxyl groups on the polyol. This is an important parameter to monitor and control during polyol production. The laboratory method that is commonplace for hydroxyl number determination is both time consuming and involves the use of hazardous materials. This note will discuss the use of Guided Wave hardware and software tools for the measurement of hydroxyl number in polyols using fiber optic-based, Near-Infrared (NIR) spectroscopy. NIR can be applied in real time directly in process or as a laboratory procedure. In either case NIR is a time and money saving alternative to traditional methods. NIR also offers the benefit of increased safety over traditional methods. For well established process measurements, a Guided Wave ClearView® db multi-wavelength photometer can be used to achieve similar results.

  • Classification and identification of recyclable material

    This level is expected to reach over 4 million tons by 2010. Companies that specialize in recycling carpet require a fast, reliable and accurate means of identifying the carpet face fiber type entering recycling streams. Collection of plastics for recycling is increasing rapidly. Plastic recycling faces one huge problem, plastic types must not be mixed for recycling. Even a small amount of the wrong type of plastic can ruin the melt. Whether it is a carpet or plastic, classification and identification of recyclable material can be achieved using Bruker Optics` state of the art spectrometer systems. Bruker Optics has applied the FT-NIR technology and experience to this demanding requirement, and offers the Carpet Analyzer as a dedicated solution for the recycling industry.

  • Pipeline Monitoring Systems for Health Monitoring

    Pipeline management presents challenges that are quite unique. Their long length, high value, high risk and often difficult access conditions require continuous monitoring as well as an optimization of maintenance interventions. The main concern for pipeline owners comes from possible leakages that can have a severe impact on the environment and put the pipeline out of service for repair. Leakages can have different causes, including excessive deformations caused by earthquakes, landslides or collisions mobile objects, corrosion, wear, material flaws or third party intrusion.

  • Dams and Dikes Structural Health Monitoring Systems

    The control of a dam requires a wide range of important information coming from the sensors, which are of vital importance for the life of a dam. Engineers in charge can take specific and sudden decisions for a correct control of a dam`s reservoir, body and foundations. However, monitoring is not only carried out by sensors, but it also involves direct or remote visual inspection as well as topographical measuring.
