For more than 60 years, GfG has been committed to protecting people, industrial facilities and the environment by developing and manufacturing gas detection systems. With an extensive range of portable gas detectors and fixed gas detection systems, GfG can supply you with a selection of products for many applications and industries. Our scope also includes on-site service and advanced training courses.
We are specialists for gas detection solutions, not generalists in safety. No one can be the best at everything, but if you focus on one thing, you can achieve excellence. We work hard to provide you with the best gas detection equipment available, so you can focus on your task without having to worry about the risks that gases can pose. Because of that we invest more heavily in research and development than any other company. Approximately 13% of our annual turnover is reinvested in basic research and the development of new sensors and devices.
This includes finding solutions for customers whose requirements are not met by “off the shelf” products. We take pride in our longstanding cooperation with the Singapore Civil Defence Force (SCDF), for example. For many years now, they have put their trust in GfG’s portable devices, which we optimized to adapt to the Singaporean climate and fulfill the special requirements for integration into the SCDF communication network.
Most gas sampling systems are bulky, heavy and expensive. To offer a compact all-in-one solution that can still be individually and modularly expanded, we developed the GMA200-MGSS. With the capabilities of a complex gas sampling system, it is still not larger than our GMA200 series controllers in a wall-mounted housing. The MGSS is easy to mount, easy to maintain, safe and reliable.
Adaptable for difficult conditions
The modular concept allows perfect adaptation to the requirements of the plant to be monitored. Whether a simple solution for one gas or a full GSS for sequential monitoring of three gases from six intake points is required, the MGSS is the best choice for measuring gases in hot, humid, cold or dusty environments. To ensure accurate monitoring as well as long sensor life, a water barrier, condensate trap and suitable cooling coils are available as accessories. Equipped with a flame arrester, even samples from an Ex zone can be aspirated and analyzed.
Suitable for a wide range of gases
The sensor block can accommodate up to three sensors. Two electrochemical and/or infrared sensors and one catalytic combustion sensor can be integrated to monitor oxygen concentration, toxic gases and combustible gases down to the lower explosion limit. An overview of the measurable gases can be found at the bottom of this page.
Expansion possibilities
The MGSS has eight internal relays, six of which are individually programmable. Up to four relay modules GMA200-RT or GMA200-RTD (16 relays each with one normally open contact) can be connected via the GMA bus. At the maximum expansion level, 70 freely programmable relays are possible. In addition, up to twelve external transmitters can be connected via the digital RS-485 interface if needed. The data logger stores all measured values and events on a microSD card for subsequent evaluation.
Quick assessment of the hazardous situation
The current measured values, operating status and alarm level can be read directly from the MGSS, which features a color backlit display and status LEDs for this purpose. In addition, a red LED bar for a clearly visible alarm and a buzzer for an acoustic alarm are integrated. On-site operation and alarm acknowledgement is accomplished via five buttons next to the display. Configuration is performed via the USB interface, a laptop or PC and the GMA200Config software. All measurement data of the GMA200-MGSS can be displayed centrally and in a clear manner on a monitor or PC using optional visualisation software.
