PRODUCT DESCRIPTION

The DURAG Flame Monitoring System from the DURAG Group consisting of a D-UG 110 or D-UG 120 Control Unit in combination with the D-LE 103 Flame Sensor is able to monitor flames of all burner types, fuels and combustion modes. The D-LE 103 Flame Sensor is available for different spectral ranges from UV to IR. UV flame sensors are mainly used for gas firings, whereas in the case of liquid and solid fuels it is the high emission in the IR region that will be evaluated.

These flame sensors have a range of spectral choice. The choices are 190 to 260 nm, 190 to 520 nm or 280 - 410 nm depending on the model. All blue-burning flames, e.g. gas flames whose portion of visible light is low may be monitored by these flame sensors.

Due to the potentially high risk of combustion processes every flame monitor should meet the highest standards for safety therefore the design of the D-UG 110/120 and D-LE 103 Flame Monitoring System is fail-safe and periodically performs self-checks. A dual channel microprocessor system ensures a safe operation of the flame monitor all the time.
