Insulated electrodes are used in three roles, as igniters, flame
detecting probes or liquid level probes in conjunction with appropriate
control equipment. In the igniter and flame detetector applications
sealing of the conductor to the ceramic is unimportant, but
for liquid level control it generally is, particularly in steam raising
or other process plants where the process involves pressure.
CUMITUFF® Ignition Electrodes, by the use of 95% Alumina as
insulator, possess superior mechanical strength and excellent
thermal shock resistance. The sealed construction makes the igniters
ideal for use as probes in liquid level controls and flame
detectors. Leading Indian manufacturers of packaged boilers now
rely entirely on CUMITUFF® Igniters.
