GfG Instrumentation Commercial and Industrial Fixed Point Gas Detection Systems


GfG's fixed gas detection systems are available as either easy to operate single point units or as larger, multiple point systems. These systems consist of controllers and up to several hundred transmitters that communicate with each other. The transmitter converts the measured gas concentration to an electrical signal which is then transferred to the controller. The controller displays the gas concentration and immediately activates alarms in case of a gas leak. Advanced features such as data logging or online data transmission allow the user to easily monitor changes in the environment. The stand alone unit is a combination of one transmitter and one controller.


Controller Modules
- Processes the electrical signal received from the transmitter, evaluating and displaying the measured gas concentration.

Gas Transmitters
- Each transmitter can have different gas sensors to choose from. The transmitter's sensor is the "nose" of a fixed gas detection system. The sensor is located in a metal sensor enclosure which is attached to the transmitter. Electronics inside the transmitter convert the gas concentration into an electrical signal for interference free transfer to the controller. The transmitter and the controller can be installed several hundred meters apart from one another.

Stand Alone Systems
- Stand alone units are designed for applications where only one fixed point of detection is needed. The stand alone unit is a combination of one transmitter and one controller. The sensor detects the gas and converts the concentration into an electrical signal which is processed inside the unit. The stand alone unit is equipped with relays that activate external alarm devices.
