Gas Monitoring with the GMA 81 A
The GMA 81 A by GfG is a fixed gas controller designed to ensure industrial facility safety by detecting various hazardous gases in ambient air. This device is compatible with different transmitters, allowing continuous monitoring of combustible gases, toxic gases, and oxygen.
The GMA 81 A features a robust design and an intuitive user interface. It stands out with its three-digit digital display, which provides real-time readings of measured gas concentrations. Its menu allows easy configuration of alarm thresholds, offering operational flexibility suited to various site needs. Three alarm levels can be preset and are triggered when critical thresholds are exceeded.
The device is equipped with a peak concentration memory system, enabling analysis of gas level variations over a given period. Its integrated diagnostic mode ensures reliable and precise detection while signaling potential anomalies through LED indicators and audible and visual alarms.
The GMA 81 A includes configurable relays that allow connection to external alarm or emergency shutdown devices. It also offers an analog output (4-20 mA) for easy integration into a centralized monitoring system. Protection against malfunctions and storage of modified parameters ensure stable and reliable operation.
Designed for long-term use, the GMA 81 A complies with current safety standards, particularly those for detecting explosive and toxic gases. Its compact and robust housing enables wall mounting in various industrial environments.
By integrating the GMA 81 A into a gas monitoring system, you ensure optimal protection against risks associated with hazardous gas leaks. Its simple maintenance and durability make it an ideal solution for chemical, petroleum, pharmaceutical, and manufacturing industries.
