Fort
Lauderdale, FL - Popular online HVAC retailer DtiCorp.com is introducing the brand new Honeywell U2-1018 Combination
Viewing Head and Signal Processor. The
Honeywell U2 flame monitoring system combines sensing and processing in one
package. The U2 is available in several models to provide different options.
Each model includes one, two or three sensors which share the same optical
axis. The U2 can be connected either through a detachable connector or a pipe
fitting for installations with conduit. Refer to the table below for model
numbers and options.

The UVTRON tube detector has a peak
response at 210 nm and is primarily for gas flame monitoring. This UV detector
using pulse technology is the best for low NOx gas burners and where a solid
state sensor, using flicker technology, does not provide satisfactory results.

The solid state UV photodiode has a
peak response at 310 nm. This sensor is suitable for gas, oil and coal. The
principle of flame monitoring is flicker frequency based. User selectable high
pass filters are used to reject signals that are from background radiation.

The solid state IR photodiode has a
peak response at 1400 nm. This sensor is suitable for low NOx oil and coal
burners, low excess air oil burners, and burners with a limited view from a
windbox front plate. The principle of flame monitoring is flicker frequency
based. User selectable high pass filters are used to reject si gnals that are
from background radiation.
