JC-15D Panel

When flue gas temperature increases, boiler efficiency decreases. A mere 40F increase in flue gas temperature causes an approximate 1% drop in boiler efficiency. Large flue gas temperature increases can be an indication of boiler overheating. Boiler accident insurance claims show that boiler overheating causes three out of every four accidents. The Preferred Instruments' JC-15F provides 24 hour monitoring of the boiler flue gas temperature.

Indicating Instruments

	Miropocessor-based indicating instrument with a heavy duty thermocouple assembly.
	Flue gas temperature is continuously displayed using a highly visible backlit 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 instruments by scrolling through user friendly, English-language menus.

Thermocouple Assembly Features

	Constructed of 8 gauge iron-constantan (ISA type J) thermocouple for installation in the boiler flue gas outlet
	1/2" steel open end protection tube
	Adjustable mounting flange (permitting up to 19" insertion)
	16 gauge thermocouple wire
