Installation
If your new sensor is to be installed in an existing entry port, be advised that the sensor is 100%
interchangeable with your current sensor.
For new installations in furnaces, an entry fitting must be provided at the furnace wall to permit
the sensor to extend into the furnace chamber. The furnace is prepared by drilling (ideally) a 3”
(76.2 mm) diameter hole through the wall and the insulation. A 1" (25.4 mm) coupling may then
be welded to the wall to provide the gas-tight entry. As the SuperOX TM has a 1" (25.4 mm) NPT
hub; use of conventional 1" (25.4 mm) fittings allows for appropriate installation. A combination
of 1" (25.4 mm) nipples and couplings allows for appropriate insertion depth.
Your SuperOX TM Sensor has been shipped with Teflon TM pipe tape applied to the gland, so you
may insert it directly into the furnace. When installing in a hot furnace, insert the first two
inches (50.8 mm) directly, then at a rate of no faster than 4" (101.6 mm) per 5 minutes in order
to avoid thermal shock fracture. Support the cover end of the sensor during installation.
The sensor requires a reference air supply. In addition, the SuperOX TM Sensor has been
designed with an optional cooling port that may require an additional air supply. SSi provides a
custom system, P/N 13017, that supplies both requirements.
It is imperative to emphasize that the reference air must be dry, clean, and oil free. Any
combustibles in the reference air will cause the sensor to read high in oxygen. Avoid the use of
lubricated compressed plant air. The air connection at the sensor should be made of silicone
rubber tubing to avoid problems related to the high temperatures normally encountered at the
sensor connection block. Reference air flow should be in the range of 0.2 to 2 CFH at no more
than 2 psi. Cooling air flow should be in the range of 1 to 10 CFH at no more than 2 psi.
Figure 4 and Figure 5 show installations in furnaces and glass tank regenerators.
These views show the installation of SuperOX TM probes in the walls of two different furnaces
furnace, utilizing a silicon protection tube which requires a 1 ½” (38.1 mm) coupling (or half
coupling) entry. This arrangement is typically used for extremely high temperature applications.
The wall is typically 13 ½” (342.9 mm) thick. Correct location of the sensor in the protection tube
may be accomplished by inserting a 1” (25.4 mm) coupling and appropriate length 1” (25.4 mm)
nipple between the sensor and the protection tube. There are three lengths of protection tubes
for use with sensors of 18” (45.72 cm), 27” (68.58 cm) and 36” (91.44 cm) lengths. When using
the unprotected sensor, a 1” (25.4 mm) coupling (or half coupling) can be used for direct entry.
NOTE: A protection tube is not required for use of the SuperOX TM Sensor.
