SpraySpy® – Spray characterization services
Measuring droplet size and velocity for transparent and non-transparent particles and droplets, for instance to evaluate a spray nozzle or an existing process.
Characterizing the size and velocity for each detected droplet or particle results in a diameter-velocity-diagram.
1. Preparation ( approx. 1-2- Weeks ahead, alternative on-site preparation)
· Shipping of specific material and components
· Installation and pre-tests
· Adaptation and adjustment of the system on specific requirement
· Clarification of potential extension or limitations of the measurement
· Definition of relevant parameters and targets
· Discussion of the physical impact of the expected results
· Introduction to the system and demonstration
· Execution and validation of the measurement as projected
· Variation of different parameters
· Data validation against the given physical spray parameters
· Validation of results
· Data analysis and theoretical discussion (on request)
· Mathematical and graphical preparation of results (on request)
· Data transfer (approx.. 3 working days after the measurement)
Field of Application:
· Monitoring of spray drying processes
· Characterization and certification of paint spray guns and nozzles
· Particle/Droplet size range: 1 µm-1000 µm
· Particle/Droplet velocity: 1 m/s – 100 m/s
If desired the measurements can be arranged as in directive DIN SPEC 91325 specified. Further information about this you will find here.
