Product Description

  • Danfoss LDS Flame sensors are used to detect the flame in yellow flame oil burners. They are designed for use with Siemens and Danfoss Burner Controller units. LDS sensors meet the requirements of the EN 298:2012 standard, as well as those of the RoHS and WEEE Directives.
  • The LDS sensors are based on the photo transistor principle in connection with an amplifier and convert light from the flame into a current. The flame’s characteristics and the location of the sensor influence the size of the photo current created in LDS. For this reason, LDS is available in two sensitivity levels. If a strong enough signal is not produced with the selected sensor, select a sensor with a higher sensitivity level. If the flame cannot be detected at the highest level of sensitivity, use the Danfoss UV sensor.
  • For no flame/darkness, the value must be ≤ 5 μA; for flame/light the value must be ≥65 μA.
