Measurement Services

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.

Measurement process:

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

2.    Measurement

·             Introduction to the system and demonstration

·             Execution and validation of the measurement as projected

·             Variation of different parameters

3. Finalization

·             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

Measurement Range:

·             Particle/Droplet size range:           1 µm-1000 µm

·             Particle/Droplet velocity:               1 m/s – 100 m/s

Further information:
If desired the measurements can be arranged as in directive DIN SPEC 91325 specified. Further information about this you will find here.
