DtiCorp.com is Introducing the New Honeywell LG1093AC01 Turbine Flame Sensor
Fort Lauderdale, FL – Popular online HVAC retailer DtiCorp.com (http://www.DtiCorp.com) is introducing the brand new Honeywell LG1093AC01 Turbine Flame Sensor – GE Part Number 314A5030P01. Industrial power generation gas turbine installations demand the superior protection provided by the Honeywell UV Flame Monitoring System. The Honeywell flame monitor system detects the ultraviolet radiation emitted by a hydrocarbon flame and produces an output signal to indicate a flame or no-flame condition. This system has delivered proven performance on General Electric (and GE licensee) gas turbines for more than 35 years. Land-based and off-shore applications include power generation, pumping stations, shipboard power generation among other industrial uses. A variety of sensors types, amplifier types and sensor cable lengths are available. Flame monitoring of a burner has comprised the use of thermocouples, expansion tubes, and radiation sensors. Due to the extremely high flame temperatures in process boilers, monitoring of boiler flames in large furnaces has been done mainly with remotely located radiation sensors or sonic microphone pickups, which detect the frequency of the flame.
Although the radiation sensor circumvents the problem of placing a sensor in the region of high flame temperature, it has shortcomings such as the inability to differentiate between flame radiation and radiation from the heated boiler or furnace wall regions. Thus, the flame may be extinguished and the flame detector will fail to respond. The fuel supply to the burners will continue to be discharged onto the hot furnace walls. This time lag between loss of flame and shut down of the fuel supply can cause an explosion.
There are specialized radiation sensors which sense ultraviolet radiation and others which generate signals corresponding to the amplitude of the high frequency flicker of the flame monitored. The sensors can distinguish between flame radiation and background radiation since both ultraviolet and flickering radiation find a source of excitation exclusively in the flame. The use of a flickering type radiation sensor produces an output signal that is continuously fluctuating. The fluctuation may be hard to distinguish, and the problem becomes one of accurate detection of this fluctuation.
Sensors are positioned to converge and the radiation magnitude received by the individual sensors is similar. A circuit means subtracts the output signals of the individual sensors of the pair, the steady and slowly varying components of flame radiation from the flame are effectively canceled leaving the rapidly varying difference signal for flame detection. The high frequency flame flickering is due to random pulses or burst of radiation from very localized sources in the flame, and there will always be a residual, varying component from the dual sensor system as long as the flame is present.
Features:
- High sensitivity with fast response time (0.1 sec typical)
- Amplifiers support multiple voltage requirements: 28 Vdc, 20-35 Vdc, and 115 Vac.

DtiCorp.com is Introducing the New Honeywell IRIS S550B as Replacement for S550
Fort Lauderdale, FL – Popular online HVAC retailer DtiCorp.com (http://www.DtiCorp.com) is introducing the brand new Honeywell IRIS S550B Viewing Head For Flame Monitor as replacement for Honeywell S550. The IRIS Model S550B is a state-of-the-art Flame Monitor viewing head utilizing two types of detectors, an IR (infrared) solid state and UV (ultraviolet) tube. The S550B works with the latest version of the P520/P522 signal processors. Like other viewing heads in the S500 family of viewing heads, the S550B produces output pulse rates proportional to the flame signal strength; the pulse rates are displayed at the front panel of the signal processors. But, unlike the other members of the S5xx family of viewing heads, certain parameters in the S550B viewing head (UV gain, IR gain and filter selection) can be selected or adjusted remotely from the front panel of the P520/P522 signal processors.
Once adjusted, the new parameters are stored in EEPROM in the signal processor. If power is removed from the signal processor, which powers the viewing head, and re-applied, the signal processor then automatically resends the stored parameters out to the S550B viewing head. In addition, at the front panel of the signal processors the operator may also select “CAL”, a semi-automatic mode which will help to speed up the S550B setup. Thus, the S550B is a dual-sensor viewing head where the gain and filter selections are adjusted and stored remotely by the P520/P522 signal processors.
Specifications: - Application: Flame Detector
