SYS 525 Pressurised-Gas Sampling System
Representative sampling and pressure-decoupling system for particle analysis in compressed-air and nitrogen lines at medium overpressures up to 8 bar, designed in line with VDI 2083-7 requirements.
Model Overview
| Model | Group | Positioning | Core fit |
|---|---|---|---|
| SYS 525 | Pressurised-gas sampling system | Isokinetic sampling and pressure decoupling from lines and vessels up to 8 bar | Compressed-gas particle monitoring, qualification and process control |
Key Features
Pressure decoupling
The system reduces pressure between the pressurised sampling point and an atmospheric-pressure particle counter.
Representative sampling
Probe geometry and flow monitoring support isoaxial and isokinetic extraction with minimal modification of the aerosol sample.
Medium-pressure operation
The unit is intended for gas lines and vessels operating from 1 to 8 bar overpressure.
Isokinetic status display
The measured total flow is compared with the required counter flow so the operator can observe and correct sampling conditions.
Portable operation
The 12 V DC supply supports adapter or battery-powered operation where required.
Process-monitoring fit
The system supports particle monitoring in pharmaceutical, chemical, food and other compressed-gas applications.
