SIEMENS火焰控制器LFS1系列应用介绍
LFS1单元设计为与控制单元LEC1，燃烧器控制LME39.xxxRP或可编程逻辑控制器结合使用，以监控燃油和燃气燃烧器。
典型的应用领域包括从工业燃烧器到最高安全等级SIL3，以及在船舶燃烧器领域。
火焰监控：
-如果是LFS1.1（在油上点火），则应使用经认可可连续运行的光电探测器RAR9进行。
-如果使用LFS1.2（燃气点火），则可使用经批准可连续运行的电离探针或间歇性运行的UV火焰探测器QRA2 / QRA2M / QRA4 / QRA4M / QRA10 / QRA10M进行
LFS1 units are designed for the supervision of oil burners and gas burners in combination with control unit LEC1, burner control LME39.xxxRP, or with programmable logic controllers.
Typical fields of application range from industrial burners up to the highest security level SIL3 and in the field of ship burners.
Flame supervision:
- Takes place with photocell detector RAR9 with approval for continuous operation, in the case of LFS1.1 (firing on oil).
- Takes place with an ionization probe with approval for continuous operation or with UV flame detector QRA2 / QRA2M / QRA4 / QRA4M / QRA10 / QRA10M in intermittent operation, in the case of LFS1.2 (firing on gas)
