Description

The Promo? is a light-scattering aerosol spectrometer system for particle size analysis and concentration determination that can be equipped with all welas? sensors. 

On Promo? 3000, the welas? sensors equipped with different measurement volumes, as required, can be easily connected via fiber optic cables and interchanged as required. These sensors allow reliable measurement in the concentration range from < 1 particle/cm3 up to 106 particles/cm3 and are available for measurement in gases, as well as in liquids. Please observe the "welas? sensors" product data sheet.

Unique are up to four measuring ranges in only one device:

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).

Promo? 3000 is famous for up to 128 size channels per measuring range and a concentration range from < 1 particle/cm3 to 106 particles/cm3.

A touch display ensures user-friendly operation. Measurements can be started easily, and all data, such as the current number distribution and the number concentration, as well as 24 further statistical values, can be evaluated and displayed in real time.

With Promo? as a standalone measuring device (i.e. without external computer) measurements are performed continuously. All incoming data can be stored with a maximum temporal resolution of 1 s. Promo? can therefore measure and save data over weeks independently. For data transfer, Promo? can also be integrated into a company network.

The Promo? has a standard interface and can be controlled by a process control system or by a simple Labview program.

For this reason, Promo? is especially well suited for control and monitoring applications.

Palas? offers remote maintenance for the device and data access via www.palas.de/user.

The quality in detail:

On Promo? 3000, two welas? sensors are supplied with one light source and the scattered light pulses are detected by a photomultiplier. This enables a quasi-simultaneous particle measurement at two sampling locations that are up to 100 meters apart.

With Promo? 3000 the user effectively has two scattered-light spectrometers in one device with the same device characteristics with regard to:

Particle size resolution capability

Particle size classification accuracy

Counting efficiency

Zero counting rate

The various welas? sensors are characterized by a particularly good conformity of counting efficiency and particle size resolution (see product data sheet: welas? sensors").

All welas? 2000 series sensors can be used with the Promo? 3000. The quasi-simultaneous particle size and particle quantitative determination offers particular advantages for characterising separators with fluctuating raw gas concentrations.
