Highlights
With its triple IR sensor, the Dräger Flame 1750 H2 detects hydrogen-based fires. It offers you high reliability against false alarms and its good measurement performance remains even at extreme temperatures.
Fast and safe detection
The Dräger Flame 1750 H2 is a triple IR flame detector. It detects hydrogen-based fires even at a greater distance. In just five seconds, it notifies you of a hydrogen fire (1-metre flame) at a distance of up to 40 metres. Due to its certified reliab … More informationility, the Flame 1750 H2 meets the IEC 61508 requirements for safety integrity according to SIL 2. The flame detector also has HART® and RS-485 interfaces and has low energy consumption.
Developed for hydrogen
The Dräger Flame 1750 H2 was specially developed for the detection of hydrogen fires. Its three IR sensors measure only in the 2 to 4 μm range relevant to hydrogen flames, guaranteeing high performance and a low false alarm rate. Common sources of fa … More informationlse alarms, such as hot CO2 or welding work, are no longer a problem for you.
Robust and durable
The housing is very robust and weatherproof. To protect against icing and fogging, the window can be heated automatically. This allows you to operate the Flame 1750 H2 reliably even under extreme environmental conditions, e.g. in temperatures from -6 … More information0 °C to +85 °C.
Simple verification
The built-in self-test "Advanced Optical Verification" (AOV) automatically checks the electronics and optics of the Flame 1750 H2. The three-colour LED on the front allows you to quickly see the device status. Green stands for normal operation, yello … More informationw indicates an error and red signals a fire alarm.
Key features
Fast reaction time: Less than five seconds for tested with a one-meter hydrogen fire from 40 meters distance. Avoidance of false alarms: Using three infrared sensors and sophisticated algorithms. All-weather availability: Equipped with a heated win … More informationdow to combat frost and fogging, ensuring year round functionality.
