Teledyne 9060 - Zirconium oxide flue gas oxygen analyzer - Manual (Page 30)

9060-Zirconia Analyser
Sample Piping - Connect the gas sample piping to the “sample in” port. If the process,
boiler, kiln or furnace has a positive pressure, no suction will be required. If the sample is
under a negative pressure, connect a pump to the “inlet” port as shown below. The flow
rate should be within the range of 1 to 5 litres/minute (120 to 600 scfm).
3.3 INSTALLING THE AUXILIARY THERMOCOUPLE
Weld a 1/2 inch BSP mounting socket to the flue within about 300 mm (12”), and
upstream of the oxygen probe. The thermocouple should be of similar length to the
oxygen probe to prevent flue temperature distribution errors.
3.4 SHIELD CONNECTIONS
All external wiring to the 9060 Analyser should be shielded. Do not connect shields
at the field end. Simply clip off and insulate. An extra terminal strip may be required to
connect all shields together. This should be supplied by the installer.
