Medición del polvo detrás de un filtro


Proporciona valores de medición continuos para la concentración de polvo como tendencia o valor absoluto.

El ProSens se puede calibrar y proporciona valores medidos en mg/m3. El sensor también se puede utilizar en canales de gran diámetro.
El sensor es adecuado para aplicaciones Ex y funciona incluso en aplicaciones exigentes con temperaturas de hasta 500 grados Celsius.

  • Continuous, precise and reliable dust quantity measurement (mg/m3)
  • Dust measurement possible in large channel diameters
  • Output of dust concentration as absolute value
  • ATEX-certified
  • Measurement of dust concentration at high temperatures or harsh environment
  • Trend signal or absolute value
ProSens is used for:

  • trend measurement in any dust channel
  • exact measurements even with large channel diameters
  • applications in explosion hazard zones (GasEx-Zone 1, DustEx-Zone 20)
  • the measurement of dust concentration even at high temperatures or/and in harsh environment in various industries such as: Steel, Chemistry, Food, Cement, Minerals, Pharma
  • Output: absolute value in mg/m3
  • For exact measurement even with large channel diameters
  • Measurement of dust concentration even at high temperatures

The ProSens can be installed in metal channels and pipelines.
The installation should take place away from any curves and other inserts such as flaps and valves.
The distance between the sensor rod and inserts in the channel should be at least 3 times the channel diameter in every flow direction.
Non-metallic channels must be sheathed using a metal sleeve, a metal foil or a close-mesh metal grid over a length of at least 5 times the channel diameter. After determining the installation location, a hole must be drilled in the channel wall to insert the welding casing flush. The casing is now welded into place vertically to the channel. The sensor rod is then inserted in this and fastened with a fixing screw. The length of the sensor rod should at least 1/3 and at most 2/3 of the channel diameter. It can be shortened to the respective optimal length (up to 70 mm) without a problem.
