SpraySpy – Analysis and monitoring for Sprays & Atomization

IMG_0519

The analysis of drops and particles in flows is often an essential monitoring or diagnostic task in process engineering, for example in spray coating. For various reasons existing particle measurement systems are not suitable for those applications, especially if non transparent drops, like in suspensions or emulsions, are to be characterized in size and velocity.

Different patented innovations are combined in SpraySpy®. The result is a real-time in-situ measurement system for R&D and inline process measurements.

Facts:

– Measurement of the individual droplet velocity and size

– Detection of the volume flow rate, the droplet momentum and the concentration of particles within droplets are possible
– Analysis of all kind of liquids
– Non invasive and inline measurement, developed for inline applications in production processes
– Flexible and convenient useage
without calibration
– Explosion protected (ATEX) and high voltage proof version for electro static painting available

Field of Applications: 

– Various R&D applications
– Monitoring of spray processes for the quality management
– Characterization or comparision of sprays, lacquers, nozzles or spray guns
– Smart maintenance of spray equipment

Measurement range:

– Droplet & particle size range: ~ 1 µm – 1000 µm
– Droplet velocity:                          1 m/s – 100 m/s

Measurement for the quality monitoring of the droplet size and velocity at a bell atomizer using SpraySpy

In order to monitor the spray parameters (bell rotation, shaping air and volume flow) SpraySpy was used to detect variations in the spray parameters. Therefore, the droplet size and velocity was measured with varying spray parameters.
