Gas monitors

The central control and monitoring element of an entire gas detection system is the Gas monitor. Gas monitors receive and process all signals from gas detectors or sensors that measure the gas concentration at the point of use. They evaluate these signals, compare them with set points and immediately trigger alarm or control functions if these are exceeded. It is essential where continuous monitoring of gases is required – be it in industrial plants, Cooling or heating systems, Underground car parks or Laboratories.

In contrast to mobile gas monitors, a gas warning system with a Gas monitor works automatically and permanently – it monitors the environment even when no one is present. This enables reliable monitoring and rapid protection against hazardous gases, toxic gas mixtures, flammable gases or oxygen deficiency.

How does a Gas monitor work?

The electrical signals from the connected gas detectors (e.g. via 4-20 mA, digital bus connection or other interfaces) are received by the Gas monitors. The control panel uses the sensor data to detect when potential hazards exist – be it toxic or combustible gases or a lack of oxygen. Alarm or threshold values set in advance then automatically generate warnings or countermeasures.

Common answers are:

• Acoustic and/or visual alarm signals to warn people
• In case of gas formation: activate ventilation systems, extraction systems or ventilation.
• Close systems or valves to prevent explosions or poisoning
• Reporting to higher-level control or building management systems

Gas monitors of the latest generation with modern equipment can store and display events (such as alarm or error messages), offer multi-zone monitoring and allow individual configuration based on the type and number of connected sensors.

Plus points of a central gas warning solution

• 24/7 monitoring – regardless of whether people are present or not. Particularly important in Industry, storage, basement or technical rooms.
• Central control & automation – alarms and safety measures can be triggered automatically: Ventilation, shutdown, warning – all without manual intervention.
• Flexible and scalable – a Gas monitor can be operated with a few or several dozen sensors, depending on requirements; perfect for small and large installations.
• Protection for people and systems – toxic or flammable gases and oxygen deficiency are identified at an early stage to prevent dangerous situations.
• Integration in building technology / management systems – Gas monitors can be connected to Ventilation, Alarm or Automation systems and are therefore part of a comprehensive safety concept.
• Common areas of application

Gas monitors are used wherever automatic and permanent gas monitoring is required. These include

• Production and industrial plants that contain chemical processes or where gases are stored or processed
• Refrigeration systems, cold rooms or Heat pumps with refrigerants or gases that are used or released
• Heating, ventilation and air conditioning systems – such as gas heating or heating systems with a risk of gas leaks
• Underground car parks, parking garages and workshops – for monitoring exhaust gases, CO or other harmful gases
• In laboratories, workshops or technical rooms – anywhere where gases can be used or released
• Storage rooms, cellars or material rooms – especially if gas cylinders, chemicals or highly flammable substances are stored there

Why every professional gas warning system needs Gas monitors

A gas detection system with Gas monitors offers the most comprehensive safety if you are looking for a reliable gas detection solution. It combines precise detection (via gas detectors / gas detectors) with intelligent analysis and automated protective measures – and therefore fulfills far more than the function of individual portable gas detectors. Especially in commercial, industrial or technical installations, it is often required by law or recommended. For this reason, a Gas monitor is the central element of any gas detection solution worthy of the name.

With such a system, you significantly increase the safety of people, buildings and systems – and create the confidence that gas risks will be detected at an early stage and reliably eliminated.
