LFE10系列火焰監(jiān)測器
品牌：SIEMENS（西門子）
產地：德國
產品介紹
The LFE50... together with the QRA50M / QRA51M b 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 supervisionand can therefore be used in connection with oil burners, gas burners and gas / oilburners. Automatic startup and control of these burners must be ensured with a controlunit 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 b.
?
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.
