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 safeguardLFE50... 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 ofmanually operated burners.

  • Prerequisite for the use of the DETACTOGYR system is sufficiently high UV radiationat the flame detector’s mounting location.

  • For combustion plant where heat generation must also be ensured in the event theflame supervision system fails, active redundancy circuitry can be accomplished byusing 2 DETACTOGYR systems.
