Promo® system

The Promo® aerosol spectrometer system was specially developed for continuous process monitoring and is based on the welas® digital technology. Besides particle size distribution and particle concentration, up to 36 static distribution parameters are continuously measured with a minimum temporal resolution of 1 s.Unique are up to four measuring ranges in only one device: 0.12 µm – 3.5 µm (additionally in welas® 1000 and Promo® 1000) 0.2 µm – 10 µm 0.3 µm – 17 µm 0.6 µm – 40 µm 2 µm – 100 µm (additionally for sensors 2300 and 2500). welas® digital system and Promo® system are famous for up to 128 size channels per measuring range and a concentration range from < 1 particle/cm3 to 106 particles/cm3. Promo® is a standalone measuring device equipped with an easy-to-operate integrated PC with touchscreen.By means of various interfaces, such as Modbus, Promo® can be integrated in process control systems and operated with external software.Unique in the world: The broad spectrum of easily exchangeable welas® aerosol sensors enable perfect matching of the measurement technology with the particle spectrum (120 nm to 100 µm) to be measured, in particle concentrations of < 1 particle/cm3 up to 106 particles/cm3, also in overpressure up to 10 barg and in temperatures of -120 °C to 470 °C. Calibration can be performed on-site independently by the customer!
