Installation Hints:
The sensor will need to be supported while being installed. The installation process will take 1
to 4 hours depending upon sensor length and rate of insertion. When the sensor is in its final
position, it is recommended that the opening be covered or filled with fiber blanket around the
protection tube.
NOTE: The sensor is warranted against workmanship defects, but not against damage caused
by installing the sensor incorrectly.
1. SuperOx TM - Maintenance
It is important to check the sensor’s position every one to two months. If the fiber placed
around the protection tube and the bored hole has shrunk, add fiber into the area between the
protection tube and the bored hole. Use wooden sticks or dowels. Touching the HOT ceramic
tube with a metal screw driver is NOT recommended.
The sensor head should be observed for any excessive temperature. The internal workings of
the sensor head will ideally be exposed to temperatures no greater than 150 to 200°F (65 to
93°C).
During troubleshooting, it may be necessary to read the sensor millivolts from the sensor. If
you are asked to supply this information, please remove the electrical connection from the head
of the sensor and, using a digital voltmeter, measure the sensor millivolts by touching pins “1”
and “2,” and then observing the number reading. The number should be between 30 and 125
millivolts during a firing cycle. Check the reading against a millivolt vs temperature Oxygen
Chart. You can check the temperature by measuring the millivolts across pins “3” and “4”.
These values can be correlated using a “B-Type” thermocouple chart.
2. Reference Air System - Installation
The reference air system should be installed in an area protected from excessive heat and dust.
It is recommended that it be installed on a column or wall, at a height easily accessible for
maintenance of the air pump. The system should be installed with respect to local electrical
regulations. The reference airline needs to be run from the reference air system to the head of
the sensor. The line can be run using ¼ inch (6.35 mm) tubing (stainless or copper). Terminate
the tubing approximately 6 inches (152.4 mm) from the sensor head and finish the connection
with flexible tubing included in the sensor carton.
3. Reference Air System - Maintenance
The reference air system requires little maintenance. Changing the filter (dependent on the
dust level) 4 - 6 times per year ensures that the sensor receives a quality source of reference
air for proper function. The amount of reference air supplied to the sensor should be
maintained at 0.5 – 1.5 SCFH. The reference air pump needs to be checked periodically to
ensure proper operation.
