Inline Gas Analysis System for Monitoring Pressurized Industrial Sources

The AWS3 system facilitates the continuous inline monitoring of gas concentrations within modified or technical atmospheres. Applied primarily in sectors such as food packaging, metal processing, and industrial manufacturing, the unit is available in configurations for O2, CO2, or combined measurement. This capability allows for the oversight of gas supply lines to maintain process specifications and verify the integrity of the atmosphere within the production chain.

Pressure Compensation and Measurement Stability
The internal design of the system incorporates pressure compensation mechanisms intended to maintain reading accuracy despite variations in line pressure. This feature is necessary for ensuring long-term stability in technical processes where pressure fluctuations could otherwise lead to measurement deviations. By using integrated sensor technology, the device provides real-time data on gas composition, supporting consistent quality assurance and reduced rework in sensitive applications.

Response Mechanisms and External Control
Operation is managed through an interface that provides manual calibration options and continuous limit value monitoring. When pre-defined gas concentration tolerances are exceeded, the system activates audible and visual alarms. To facilitate automated responses, a potential-free contact outputs 0–10 V or 4–20 mA signals. This allows external plant control systems to trigger corrective actions, such as process shutdowns, to prevent the use of incorrect gas mixtures.

Data Integration and Communication Protocols
For process documentation and plant-wide communication, the AWS3 includes Ethernet connectivity and an onboard data logger. The system supports industrial communication protocols, including OPC UA and Modbus TCP, allowing for the transfer of technical data to central management systems. Email notification options are available to alert maintenance personnel of alarm states, localized or remote, to assist in minimizing potential downtime.

Technical Integration and Housing
The hardware is contained in a splash-proof stainless steel enclosure to comply with hygiene standards in food and pharmaceutical production environments. This construction supports standard cleaning procedures used in high-purity sectors. Furthermore, the analysis unit can be integrated with existing WITT gas mixers, specifically the KM and MG models, to establish a unified solution for the supervision and documentation of gas quality across the entire line.
