Fidas® Sense Sensors

Aerosol sensors for indoor production, process and environmental monitoring

The Fidas® Sense system are high-resolution aerosol sensors for indoor use.

The Fidas® Sense 2900 sensor measures particle number concentrations in single count mode up to 200 particles/cm³. This makes it suitable for use in environments where particle contamination is critical to the product or process.

Fidas® Sense 2300 can analyze up to 20,000 particles/cm³ in single count mode with size resolution. Thus, it is designed for general indoor and hall air monitoring, but also in driver's cabs or similar areas to ensure occupational health and safety.

The sensor system calculates and transmits the specified parameters at 10-second intervals via the integrated USB interface directly to the connected computer system using suitable software for further processing.

Operation principle

Your special advantages

  • Direct evaluation of data and provision for further processing
  • Mechanically robust, durable and free of maintainance
  • Unambiguous and specific calibration of particle size determination via NIST-retraceable monodisperse aerosol
  • Long-term stable light source with long service life
  • 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

Individual solutions for various industries

  • 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:
    • Large-scale ventilation and air-conditioning systems
