Flame Scanner Sensor YFD-5

Product Description

  [European instrument measurement and control YFD-5-918H intelligent integrated flame detector mechanical parameters]:

  Housing material: die-cast aluminum housing with grey polyester housing

  Shell weight: 3.1 lbs (1.41Kg), except for external flanges

  Environmental requirements: NEMA 4X, IP66

  Installation requirements: A mounting flange with two threaded connections is required and must be ordered separately. (as follows)

  Mounting flange: P/N 60-2692, 1” NPT inner pipe thread with 3/8" NPT inner pipe thread cooling air interface, including a heat insulating tube (P/N35-127-1), 1”NPT × ; 3”.

  P/N 60-2693,1”BSP inner pipe thread with 3/8" BSP inner pipe thread cooling air interface, including a heat insulation pipe (P/N35-127-3), 1 & rdquo; BSP X 3 & rdquo;.

  Mounting flange weight: 0.71 lb (0.32Kg)

  Cooling / purge requirements:

  Source: clean, dry, low temperature

  Flow rate: 4 SCFM (113L/MIN), accessed by the 3/8” threaded connection on the mounting flange.

  Or 1”NPT on the "Y” type tee mounted on the detector tube

  Threaded connection port is connected. If the ambient temperature is near the upper limit of the detector operating temperature, or when using dirty/dusty fuel, the required cold air flow needs to be increased to 15 SCFM (425L/MIN).

  Pressure: Appropriate pressure above the furnace or bellows.

  Temperature range: -40 °C — 65 °C

  Humidity: 0% — 95% relative humidity, non-condensing

  Installation Precautions:

  The YFD-5-918H flame detector defines the presence or absence of a flame by monitoring the spectral frequency of the flame. The detector should have the main fuel zone within the detector line of sight during initial installation.

  The mounting locations and line of sights listed below are a guide to the general detector position. The detector helps to debug and calibrate the detector through feedback from the LED display. Refer to the setup procedure section described in this manual.

  Note: The proper detector installation location must ensure the following:

  Reliable detection of main flame and/or ignition flame (within fuel combustion range) under all air volume conditions and furnace load

  If the ignition flame is too short or in the wrong position and the main flame cannot be reliably ignited, the ignition flame is considered to be absent. Do not deliver fuel to the burner.
