Fidas® Sense Sensors

Fidas Sense Sensors

Aerosol sensors

The sensors manufactured by Palas® operate on the proven principle of single particle measurement using the scattered light method with high resolution to determine the distribution of particle size and concentration. For years they have been used in industry and science for the analysis and evaluation of airborne particles as well as in official and continuous fine dust monitoring according to the EN 16450 standard.

Like all sensors of the Fidas® line, the sensors can be easily calibrated on site using monodisperse particles and thus allow a constant and stable measurement of particle concentration values and mass fractions of PM1 – TSP.

FEATURES & BENEFITS

  • Direct evaluation of data and provision for further processing
  • Mechanically robust, durable and free of maintainance
  • No consumables and therefore low maintenance
  • Optics can be cleaned by trained personnel – high availability
  • Closed housing (protection class IP67) and therefore easy to clean
  • Various quality-determining monitoring & control parameters such as:
    • Number concentration CN
    • Aerosol size distribution PSD
    • Detection of specific concentrations of a particle size or area
    • On-line calculation of mass concentrations in aerosols
  • Control, monitoring or regulation of, for example:
    • Particle analysis for quality monitoring of particle-generating production processes (e.g., Pharma)
    • Large-scale ventilation and air-conditioning systems
    • Process and contamination monitoring
    • and many more
