JC-15D2
Flue Gas Temperature Monitor
Installation & Operation Instructions
Why should Flue Gas Temperature be Monitored ?
Every 40 F increase in Flue Temperature results in an approximate 1% decrease in Boiler/Furnace Efficiency.
High Flue Temperature can indicate a need to clean soot or scale build-up on the tubes.
High Flue Temperature can indicate fallen refractory, baffle damage, short circuiting, or overfiring.
High Flue Temperature can indicate insufficient feedwater
Hartford Steam records show that Boiler Overheating is the primary reason for Boiler Damage.

Description
The
JC-15D2
Flue Gas Temperature Monitor is a digital Indicator and Alarm. Flue gas
temperature is displayed on a backlit color touchscreen LCD display. An intuitive
bargraph display and alarm messages provide clear stack temperature status. Bargraph
Scaling, Alarm Setpoints, and Time Delays are all field selectable. All adjustments can
be made directly from the faceplate of the instrument by navigating through user friendly menus. JC_Edit PC software can also be
used to configure the
JC-15D2
via the USB port and to import the Alarm/Event History into JC_Edit.
Any J or K thermocouple can be used with the
JC-15D2
to sense the temperature. The 20” 104087D and the 12” 104087E are
constructed with an Inconel sheath for corrosion protection, ½" male NPT process connection, cast iron head with terminal block,
and ½" female NPT electrical connection.
