S-POP: Mono-optical probe for atomization and dense spray analysis

Product catalog summary

Overview
The S-POP is a mono-optical probe designed for atomization and dense spray analysis, offering simultaneous measurements of concentration, droplet velocity and size, flux, local flow rate, chord-velocity correlation, and various diameters (D10, D32, etc.). It is a unique technology that complements existing spray analysis tools.

Technical Specifications

Concentration Range: 0 ≤ α ≤ 100%
Velocity Range: 0.1 ≤ U ≤ 25 m/s (expandable on demand)
Operating Conditions: Up to 30 bar / 250°C (expandable on demand), with flow viscosity up to 30 times that of water
Minimum Detectable Drop Size: Drops > 15 µm
Uncertainties: ± 5% on concentration, ± 15% on velocity and size
Laser Source: 830 nm, 3 mW, class 3R

Working Principle
The S-POP operates by measuring the reflection of a laser beam at the probe tip, sensitive to the refractive index of the surrounding phase. It detects phase changes at a specific location, with velocity measurements based on the propagation of the liquid-gas interface along the sensing tip. The device works by contact, allowing operation in dense environments without requiring light propagation outside the probe.

Product Offerings

Standard Products: S-POP, B-POP, i-LDA
