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.

Applications

Emission monitoring of installations

Control of grinding and classification processes

Monitoring of production processes in the food, pharmaceuticals and chemicals industries

Testing of complete filters, inertial and wet separators or electrostatic precipitators

Using opto-mechanical switching, the two sensors that are connected can be easily controlled. The sensors are controlled automatically with the software.

The particular advantage over a manual measurement selector switch:

Faster change of the measurement location

No deposits in sampling lines

Long service life; no wear of the seals due to dust particles

The Promo® measurement technology:

The Promo® has a new, fast 20 MHz signal processing processor, which analyses the interference of each particle. This makes it possible to recognise coincidental events on the basis of the scattered light signal, i.e. more than one particle in the measurement volume at one time can be identified from the individual signal and corrected (according to Dr. Umhauer / Prof. Dr. Sachweh).

This makes it possible to increase the maximum concentration limit up to 106 p/cm3 (welas® 2070 sensor). Also in low concentrations < 1 particle/cm3 with the welas® 2500 sensor, this leads to a higher measuring accuracy.

High classification accuracy and high particle size resolution (see Graph 1) are guaranteed by the following special features:

White light and 90° light-scattering detection 

→ Unambiguous calibration curve

Patented T-aperture 

→ No border zone error

New digital individual signal processing 

→ Coincidence detection and correction of the individual signal making it possible to measure higher concentrations.
