Stack Sensor Kit
Description:
A high stack temperature indicates inefficient
boiler operation; i.e. sooted boiler. Monitoring the
stack temperature can lead to prompt maintenance,
increasing performance, and preventing boiler
damage.
•Constant Display of Stack Temperature. Thus,
giving the user an immediate access to the current
temperature.
•Alarms can Visual, Audio, or sent an EMS Remote
Alarm. The SPC Elite control connected to the
stack sensor can trigger an alarm whenever, the
stack temperature rises to a critically adjustable set
point. The SPC Elite output can then be connected
to either an audio-visual alarm as the Vis-U-Alarm
(must be ordered separately) or to the BMS/EMS
system to trigger a digital alarm.
