LSS1 is a compact single-channel optical measurement probe for droplet and particle characterization. It is used with SprayQuantAI® SQA1 and ParticleTensorAI® PTA1.
The physical probe hardware is identical for both systems. Whether the measurement system operates as SQA1 or PTA1 is determined by the signal acquisition concept, firmware, and evaluation software used in the connected ZEON control unit.
Measurement Principle
Droplets or particles pass through a specifically shaped light beam in the measurement region. Their interaction with the illumination produces a characteristic scattered-light intensity distribution. Because the particle moves through the light field, this spatial information is transformed into a time-dependent optical signal.
The scattered light is detected by the active detector channel and transferred through the optical connection to the ZEON control unit for acquisition, processing, and evaluation.
Compatible Systems
LSS1 is operated together with the ZEON control unit. The same optical probe can therefore be used with two different measurement concepts.
| System | Control Unit | Evaluation Concept |
|---|---|---|
| SQA1 | ZEON | Individual-event evaluation; classical or AI-based |
| PTA1 | ZEON | Buffered ParticleTensorAI® analysis; AI-based evaluation |

Single-Channel Measurement
LSS1 uses one active detector channel and represents the most compact optical configuration within the LSS probe family. The time-resolved signal from this channel contains information about the interaction of an individual droplet or particle with the shaped illumination field.
In SprayQuantAI® SQA1, the signal is evaluated on an individual-event basis. Particle or droplet properties can be determined using classical signal-processing methods or AI-based evaluation, depending on the configured measurement method.
In ParticleTensorAI® PTA1, the same detector signal is continuously recorded and combined over a defined acquisition interval. The resulting buffered signal data are processed using the ParticleTensorAI® approach to characterize the particle population, spray behaviour, or material-related properties.
Optical Configuration
LSS1 is based on the same fundamental optical principle as LSS2 and LSS4. A shaped illumination field converts the spatial interaction of a droplet or particle with the light into a time-dependent scattered-light signal.
The probe can be adapted to the measurement task. Depending on the application, parameters such as working distance, optical alignment, mechanical mounting, and integration into the atomizer, spray gun, nozzle, or process equipment can be customized.
Typical Applications
- Droplet and particle characterization
- Compact spray measurement systems
- Spray process monitoring
- AI-based evaluation with SprayQuantAI®
- Material and particle characterization with ParticleTensorAI®
- Measurements on spray guns and nozzles
- Customized integration into industrial processes
Integration into Measurement Systems
LSS1 is designed as part of a complete measurement chain. The optical probe, optical connection, ZEON control unit, firmware, and evaluation software together form the measurement system.
For industrial applications, the probe can be mechanically adapted to the atomizer, spray gun, nozzle, or production equipment. This allows the measurement region to be positioned according to the specific spray geometry and process requirements.
