Working in areas with combustible gases, vapours or materials requires fire/flame detection as a life-saving necessity. The best solutions must combine state-of-the-art technology with rugged durability and be ready to reliably work in any situation. Dräger offers a wide variety of high-quality flame-detectors that fulfil these requirements.

Benefits

A Multi-Talent With More Features

• The SharpEye™ 40/40L4 and the L4B model (with built-in test option) are both offered by Dräger and combine UV and IR sensors that are capable of detecting hydrocarbon-based fuel and gas fires.

Rugged Yet Refined

• The 40/40L4-L4B are designed to cope with harsh weather conditions and come with such features as a heated window against snow, ice and condensation and a rugged outer housing. At the same time, both models are compact and lightweight, making them ideal for any situation or installation set-up. In addition to many other innovative features, the device comes with DNV and MED shipping approval.

Automatic and manual optics checks (BIT)

• Automatic checks of the detector electronics and optics helps ensure that no fault goes undetected. Additionally the test can be triggered manually at any time.

Performance You Can Trust

• The UV/IR flame detector senses radiant energy in the short wave section of both the ultraviolet and infrared portions of the electromagnetic spectrum. The signals from both sensors are then analysed for frequency, intensity and duration. The simultaneous detection of radiant energy in both the UV and IR sensors then triggers the alarm.

Simple installation and commissioning

• Installation is simple! The detector is easily installed with a stainless steel tilt mount; enables the detector to be rotated up to 60° in all directions to position the detector in relation to the potential fire source.

Reliability

• Functional safety is a concept applicable across all industry sectors. It is fundamental to enabling complex technology used for safety-related systems. It provides assurance that the safety-related systems will offer necessary risk reduction. The SharpEye™ 40/40 flame detector series is highly reliable and complies with the IEC 61508 Safety Integrity Requirements of SIL2.

Easily visible status LED

• A tri-colored LED which is visible at the front of the detector provides a simple status indication to personnel in close proximity to the detector. Green indicates normal operation; yellow indicates a fault and red indicates the presence of radiation from a fire.
