DtiCorp.com Is Introducing The LG1093AA24 And LG1093AA26 Flame Sensors

Fort Lauderdale, FL – Popular Honeywell online retailer DtiCorp.com (http://www.DtiCorp.com) is introducing the Honeywell LG1093AA24 and LG1093AA26 Gas Turbine Combustion System Flame Detectors – replacement for GE Part Number 261A1812P012. 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.

- Dehumidification features can be used to control dew points in buildings and can be deployed where moisture is an issue, such as around school pools or in humid locations.

- Temporary Override can be configured from 1 to 8 hours to allow override from unoccupied schedule to an occupied schedule as well as for classrooms that are only used for parts of the week or just occasionally used.

- Control Algorithm is the best available for heating and cooling large spaces, such as gymnasiums or auditoriums, quickly and accurately. The algorithm is specifically tuned for commercial equipment and has a short sensor time constant that can react quickly to demand changes.

Healthcare and Gym Facilities

- Dehumidification features are ideal for controlling high-moisture areas.

Restaurant/Food Service

- Commercial Algorithm provides the best comfort control to react to the constantly changing food service and restaurant environments, reacting quickly to changing load demands via fast-sensing time constants.

- Remote Sensing configuration options allow the use of commercial 20K ohm and 10K ohm sensors to create a 20K ohm averaging network, a good solution for food service locations that have high load demands.

- Economizer function allows restaurants to meet ventilation requirements and is also important to balance the air intake of the restaurant. Restaurants that are not properly balanced do not achieve good comfort control as they draw in unconditioned air.

Churches/Public Worship

DtiCorp.com Is Introducing 10 Honeywell DS06 Pressure Regulating Valves

Fort Lauderdale, FL – Popular Honeywell online retailer DtiCorp.com (http://www.DtiCorp.com) is introducing 10 Honeywell DS06 Pressure Regulating Valves. The Honeywell DS06D,G Dial Set is a balanced, direct acting pressure-regulating valve. It provides constant downstream pressure regardless of varying inlet pressures and downstream flow demands. The spring force holds the valve in the open position until downstream pressure, sensed by a port, is sufficient to press on the underside of the diaphragm and close the valve. As downstream pressure drops due to demand, the force on the diaphragm is reduced and the valve opens. Adjustment is made by manually turning the adjustment knob clockwise to increase the spring force and require a higher downstream pressure to close the valve. Similarly, reducing the spring force lowers the outlet set pressure. A factory-calibrated dial is built into the adjustment mechanism to allow outlet pressure (under no flow condition) to be set without a gauge. A lock screw maintains the setting. A black plastic cover is provided for additional protection. When the outlet pressure is set, the DS06D,G automatically regulates to maintain the downstream pressure.

Features:

- Ideally suited for potable water and irrigation applications requiring accurate regulation.

- Wide outlet pressure range, high inlet pressure, and compact design allow flexibility in installation and application.


- Calibrated outlet pressure set dial that allows outlet pressure adjustments without the use of a gauge in most applications.
