Scattered light dust measuring devices
DUSTHUNTER SP30

Measure intelligently. Reduce costs.

Your Benefits

  • Accurate dust measurement – independently of gas velocity or particle charge
  • Convenient data transmission via Modbus® and analog output directly from the sensor
  • Versatile thanks to several configurable measuring ranges
  • Two calibration curves for switching with different dust sources
  • No external purge air unit required as it is integrated into the device (option)
  • High degree of flexibility due to different mounting options
  • Low level of expenditure and maintenance work thanks to self-monitoring

Note: The analysis devices listed below are completely configured and available with short delivery times. Furthermore, countless device configurations - even customer-specific configurations - can be delivered on request. Our regional sales organization will be glad to advise you on which device configuration is best for you.

Overview

Measure intelligently. Reduce costs.

The DUSTHUNTER SP30 is a measuring device which reliably detects very low to high dust content. The measurement is based on the forward scattering of light and is independent of the gas velocity and particle charge. The automated monitoring of the zero and reference point ensures a high level of accuracy.

Thanks to its compact design, the DUSTHUNTER SP30 is available as an independent measuring device but also with an integrated purge air unit and MCU control unit for additional functions as an option. The installation is carried out on one side of a duct, whereby several mounting options and probe lengths are available. The measuring device is highly versatile, e.g., for process optimization or intelligent filter diagnostics and monitoring.

At a glance
  • Independent measuring device – with or without MCU control unit
  • Automated monitoring of zero and reference point
  • Integrated purge air unit as an option
  • Installation on one side of a duct
  • Rugged and compact structure
  • No moving parts in the duct
