What is the Landis & Gyr LFE10?
The LFE10 is an electronic flame detector relay specifically for use on gas burners and comparable equipment. It senses flame signals via an attached flame sensor and either permits or cuts off fuel supply depending on the presence of the flame. This real-time decision capability precludes the build-up of unused fuel, hence preventing potential explosions or system destruction.
Designed by Landis & Gyr, which is famous for its control systems of top quality, the LFE10 model is in extensive use across HVAC, factories, refineries, and industrial settings.
Key Features:
• High Sensitivity Detection: Rapid detection of flame presence or absence, with minimal risk of false alarms.
• Compact Design: Simple to integrate into control panels and small-space applications.
• Reliable Output Contacts: Suitable for direct connection to fuel valves or PLCs.
• DIN Rail Mountable: Allows for simple installation and replacement.
• Voltage Compatibility: Works effectively on 220–240V AC power supply.
• Test/Reset Functionality: Manual reset facilities for maintenance testing and fault diagnosis.
• LED Status Indicators: Visual indications for flame detection and relay status.
• Compliant with Safety Standards: Constructed as per EN and DIN-DVGW standards.
• Durable Build: Designed to work in harsh industrial environments.
• Multi-Use Compatibility: Compatible with many different flame sensors, such as UV and IR sensors.
Uses of the LFE10 Flame Relay:
• Industrial Boilers – Guarantees flame monitoring to avoid the buildup of unburned gases.
• Heating Systems – Protects large commercial or industrial HVAC equipment.
• Gas Burners – Brings essential fail-safes for manual and automatic ignition systems.
• Furnace Control Panels – Connects to PLCs for automatic flame shutdown.
• Power Plants – Improves operational safety in turbine ignition systems.
• Refineries and Petrochemical Units – Critical for combustion control in high-risk zones.
• Food Processing – Employed in gas or oil flame-powered ovens and cookers.
• Pulp and Paper Mills – Safeguards drying and heat treatment areas.
• Steel Manufacturing – Guarantees safe operation of furnaces and heat treatment areas.
• Waste Management Plants – Flame relay is essential in incinerators.
Why Landis & Gyr LFE10?
Safety, accuracy, and dependability—these are the three cornerstones that make the LFE10 an industry favorite among professionals. In working with high-temperature, flame-powered systems, the price of failure can be devastating. The LFE10 not only avoids accidents but also reduces expensive downtimes by providing continuous monitoring and control. Supported by Landis & Gyr’s heritage of innovation, this flame detector relay is relied upon globally in mission-critical infrastructure.
