Instruction Manual IM-106-880, Rev 1.0 January 2007 OCX 8800 The equipment measures oxygen percentage by reading the voltage developed across a heated electrochemical cell, which consists of a small yttria-stabilized, zirconia disc. Both sides of the disc are coated with porous metal electrodes. When operated at the proper temperature, the millivolt output of the cell is given by the following Nernst equation: EMF = KT log10 (P1/P2) + C Where: 1.
Instruction Manual IM-106-880, Rev 1.0 January 2007 OCX 8800 The catalyst is specifically designed to detect carbon monoxide (CO), but the sensor responds to other combustible gases. The sensor is calibrated using CO, thus the output should be expressed in terms of CO. However, since the sensor detects other combustible gases, the output cannot just be labeled CO. The response of the sensor to other combustible gases gives an output that is equivalent to the sensor detecting CO.
Instruction Manual IM-106-880, Rev 1.0 January 2007 OCX 8800 5. An operator can calibrate and diagnostically troubleshoot the OCX 8800 using the HART Interface. Each of the OCX 8800's 4-20 mA output lines transmit an analog signal proportional to oxygen or combustible levels detected. The HART output is superimposed on the oxygen 4-20 mA output line only.

Instruction Manual IM-106-880, Rev 1.0 January 2007 OCX 8800 MECHANICAL INSTALLATION Selecting Location 1. The location of the OCX 8800 in the stack or flue is most important for maximum accuracy in the oxygen analyzing process. The probe must be positioned so the gas it measures is representative of the process. Best results are normally obtained if the transmitter is positioned near the center of the duct (40-60% insertion).
Instruction Manual IM-106-880, Rev 1.0 January 2007 OCX 8800 4. Use the pipe or wall mounting hardware as shown in Figure 2-3 to mount the electronics housing. Choose a location not to exceed the length of the electronics cable ordered. 5. Ensure the conduits drop vertically from the OCX 8800 and the conduit is routed below the level of the conduit ports on the housing to form a drip loop. Drip loops minimize the possibility that moisture will damage the electronics (Figure 2-4). 6.

Instruction Manual IM-106-880, Rev 1.0 January 2007 OCX 8800 EXPOSURE TO USED CERAMIC FIBER PRODUCT Product which has been in service at elevated temperatures (greater than 1800ºF/982ºC) may undergo partial conversion to cristobalite, a form of crystalline silica which can cause severe respiratory disease (Pneumoconiosis). The amount of cristobalite present will depend on the temperature and length of time in service. (See Section IX for permissible exposure levels).
Instruction Manual IM-106-880, Rev 1.0 January 2007 OCX 8800 The International Agency for Research on Cancer (IARC) reviewed the carcinogenicity data on man-made vitreous fibers (including ceramic fiber, glasswool, rockwool, and slagwool) in 1987. IARC classified ceramic fiber, fibrous glasswool and mineral wool (rockwool and slagwool) as possible human carcinogens (Group 2B). EMERGENCY FIRST AID PROCEDURES • EYE CONTACT - Flush eyes immediately with large amounts of water for approximately 15 minutes.
Instruction Manual IM-106-880, Rev 1.0 January 2007 OCX 8800 SECTION VIII. SPECIAL PROTECTION INFORMATION RESPIRATORY PROTECTION Use NIOSH or MSHA approved equipment when airborne exposure limits may be exceeded. NIOSH/MSHA approved breathing equipment may be required for non-routine and emergency use. (See Section IX for suitable equipment). Pending the results of long term health effects studies, engineering control of airborne fibers to the lowest levels attainable is advised.
Instruction Manual IM-106-880, Rev 1.0 January 2007 OCX 8800 IARC has recently reviewed the animal, human, and other relevant experimental data on silica in order to critically evaluate and classify the cancer causing potential. Based on its review, IARC classified crystalline silica as a group 2A carcinogen (probable human carcinogen). The OSHA permissible exposure limit (PEL for cristobalite is 0.05 mg/m3 (respirable dust). The ACGIH threshold limit value (TLV) for cristobalite is 0.
Instruction Manual OCX 8800 IM-106-880, Rev 1.0 January 2007 2. Cylinders may be stored in the open, but in such cases, should be protected against extremes of weather and, to prevent rusting, from the dampness of the ground. Cylinders should be stored in the shade when located in areas where extreme temperatures are prevalent. 3. The valve protection cap should be left on each cylinder until it has been secured against a wall or bench, or placed in a cylinder stand, and is ready to be used. 4.
