LAE10火焰监测器 的详细介绍:

LAE10系列火焰监测器

 

品牌:SIEMENS(西门子)(原LANDIS&GYR)

产地:德国

产品介绍

LFE10和LAE10都为配合西门子专用火焰探测器使用的火焰检测器。

LFE10可以与SIEMENS西门子公司的QRA...系列火焰探测器或者离子探针配合使用,把模拟量电流信号转换为开关量信号,并输出给燃烧器程控器。

LAE10可以与SIEMENS西门子公司的RAR...系列燃油火焰探测器配合使用,把模拟量电流信号转换为开关量信号,并输出给燃烧器程控器。

此两款火焰检测器必须每24小时停止工作一次。如需要24小时连续工作,请选用LFE50系列产品。

Flame safeguards for burners with intermittent operation. For safety reasons - self-test of flame supervision circuit, etc. - at least one controlled

shutdown is required every 24 hours. The LFE10 is suited for the supervision of gas flames and luminous or blue-burning oil flames in connection with UV detectors QRA... or a flame rectification probe.

Flame safeguards are used primarily in conjunction with the LEC1 burner control on the following applications:

  • Dual-supervision of burners: Supervision of the main flame or of the pilot and main flame by two identical or different types of flame detectors

  • Supervision of forced draught oil / gas burners: Supervision of the flame with different types of detectors, depending on the operating mode

  • Multi-flame supervision: Plants with several burners whose flames must be supervised individually by one or several detectors, whose startup and supervision, however, should or must be carried out centrally and simultaneously by only one burner control

  • The flame safeguards can also be used in connection with other types of burner controls provided the given combination and selected circuitry do not impair the burner controls safety functions

  • The flame safeguards are also used as flame indication units in combustion plant with manual startup
