Siemens QRA2 Burner Flame Detector Photo Cell

The Siemens QRA2 photo cell UV Flame Detector is manufactured in Germany and weighs 60 grams. This sensor is designed to detect flames in burners of the LGB2, LGB4, LFL, LFE1, LFE10, and LMG series. Its operation is intermittent, capable of detecting UV radiation changes from the flame with millisecond precision. The device includes UV accessories to enhance sensitivity and utilizes Photoresistor and Photo cell technology. Its compact size and low weight ensure easy installation and replacement in industrial environments. The QRA2 can operate within standard industrial temperature ranges and withstand typical mechanical vibrations and shocks.

The Siemens QRA2 burner photo cell improves burner safety by accurately detecting flames and preventing unexpected shutdowns. This sensor is fully compatible with LGB and LFE timers and meets European industrial standards. Its UV technology allows detection of both gas and liquid flames, with a response time of less than 200 milliseconds. Its engineering design filters out environmental noise and light variations. Related product names include Siemens eye, Siemens burner photo cell, and Siemens photo cell, optimizing search visibility in online engines.

Brahma RE3 and SM592 relay base

The Brahma relay bases models RE3 and SM592 serve as electrical and mechanical interfaces for the safe mounting and connection of control relays in combustion systems. These bases are rated for 250V AC and support a maximum current of 10 amperes. Their bodies are made of heat-resistant reinforced polyamide, allowing operation in ambient temperatures ranging from -20 to +85 degrees Celsius. The pin configuration follows the standard 11-pin layout, ensuring precise and noise-free connections. These models are DIN rail mountable with a standard width of 35 millimeters, simplifying installation in industrial electrical panels.

The RE3 and SM592 bases fully comply with international safety standards such as CE and UL, ensuring reliable operation in control circuits. The insulation distance between contacts exceeds 3 millimeters, preventing accidental short circuits. Terminal connections use screw-type clamps with a torque tolerance of 0.8 Nm. Electrical resistance between terminals exceeds 100 megaohms at 500V DC. These bases are compatible with various Brahma flame relays and timers, with a mechanical life expectancy of over 100,000 switching cycles.
