Dräger FD10 Flame Detector

Dräger FD10 Flame Detector: Comprehensive Overview and Key Features

The Dräger FD10 is a high-performance flame detector that uses advanced ultraviolet (UV) and infrared (IR) technology to detect fire. This dual-spectrum detector is recognized for its reliability and efficiency in both indoor and outdoor applications, making it suitable for various industrial settings, including hazardous environments due to its explosion-proof design.

Key Features of the Dräger FD10 Flame Detector

Dual-Spectrum Detection

The Dräger FD10 flame detector is equipped with both UV and IR sensors, allowing it to detect a broad range of fires. The UV sensor is particularly sensitive to hydrocarbon-based fires, while the IR sensor is responsive to the heat emitted by flames. This dual-spectrum capability ensures comprehensive fire detection, enhancing safety measures in diverse environments.

Wide Field of View

One of the standout features of the FD10 is its 90-degree field of view. This extensive coverage ensures that the detector can monitor large areas effectively, reducing the risk of undetected fires. The wide horizontal field of view, combined with high sensitivity, makes the FD10 an optimal choice for extensive industrial spaces.

High Sensitivity and Early Detection

The FD10 is designed with high sensitivity to flames, enabling it to detect fires at their early stages. This early detection capability is crucial for minimizing fire damage and ensuring prompt response, thereby protecting both personnel and property.

Self-Testing Capability

To maintain its reliability, the FD10 performs an automatic self-test every 60 minutes. This self-diagnostic feature ensures that the detector is functioning correctly and can detect any faults or malfunctions promptly. The self-test process is quick, taking approximately 10 seconds, during which the flame detection functionality is momentarily paused.

Alarm Output for Immediate Notification

The FD10 flame detector can be integrated with alarm systems to provide immediate notification in case of a fire. This integration allows for rapid response from fire safety teams, significantly enhancing overall safety measures. The alarm output ensures that any detected fire is communicated swiftly to the relevant personnel.

Operational Principles of the Dräger FD10

Detection Mechanism

The Dräger FD10 operates as an optical flame detector with dual-spectrum capabilities. It detects UV and IR radiation emitted by flames, with each type of radiation being processed by separate sensors. The UV sensor responds to changes in ultraviolet energy, while the IR sensor detects variations in infrared energy. This dual detection mechanism increases the accuracy and reliability of the FD10 in identifying real fire incidents while minimizing false alarms.

Automatic Frequency Modulation

The IR source in the Dräger FD10 is activated and modulated at a frequency of 0.5 Hz. This modulation helps the sensor detect rapid changes in IR energy, enhancing its ability to identify genuine flames. When the UV source is activated, it does not modulate because the UV sensor operates based on absolute UV energy levels rather than frequency changes.

Test and Fault Indication

During the self-test process, the FD10 checks both its IR and UV sensors. If either sensor fails the test, the detector indicates a fault with a yellow LED. Successful completion of the UV test within 5 seconds allows the detector to resume its normal detection state. This proactive monitoring ensures continuous and reliable operation of the flame detector.

Applications and Installation

Versatility in Use

The Dräger FD10 flame detector is versatile, suitable for a wide range of applications both indoors and outdoors. Its robust design and explosion-proof certification (Ex d) make it ideal for hazardous environments, including oil and gas facilities, chemical plants, and other industrial settings where fire hazards are prevalent.

Durability and Material Options

The FD10 is available in two material options: aluminum grade 25 LM and 316 stainless steel. These materials provide durability and resistance to harsh environmental conditions, ensuring long-term reliability and performance.

Conclusion

The Dräger FD10 flame detector stands out as a reliable and efficient solution for fire detection. With its dual-spectrum detection, wide field of view, high sensitivity, and robust self-testing capability, it offers comprehensive fire safety coverage. Its suitability for both indoor and outdoor use, combined with its explosion-proof design, makes it a versatile choice for various industrial applications. Integrating the FD10 into your fire safety system ensures early fire detection and rapid response, enhancing overall safety and protection.
