LFE50系列火焰监测器
品牌:SIEMENS(西门子)
产地:德国 |
产品介绍 |
The LFE50... together with the QRA50M / QRA51M form a self-checking UV flame supervision system (DETACTOGYR®) designed for use with continuously operating oil or gas burners or burners operating without interruption for more than 24 hours.
-
The DETACTOGYR flame supervision system consists of the UV flame safeguard LFE50... and the flame detectors QRA50... / QRA51.... It is designed for UV supervision and can therefore be used in connection with oil burners, gas burners and gas / oil burners. Automatic startup and control of these burners must be ensured with a control unit LEC1... (refer to Data Sheet 7761). The system is also suited for the supervision of manually operated burners.
-
Prerequisite for the use of the DETACTOGYR system is sufficiently high UV radiation at the flame detector’s mounting location.
-
For combustion plant where heat generation must also be ensured in the event the flame supervision system fails, active redundancy circuitry can be accomplished by using 2 DETACTOGYR systems. | |
