After selecting the probe mounting location,
provision should be made for a platform
where the probe can be easily serviced.
The intelligent field transmitter (IFT) can be
located up to 150 ft (45 m) cabling distance
from the probe when used without optional
heater power supply (HPS). When the sys-
tem includes the optional HPS, the HPS can
be located up to 150 ft (45 m) cabling dis-
tance from the probe and the IFT may be
located up to 1200 ft (364 m) cabling dis-
tance from the HPS.
A source of instrument air is required at the
probe for reference air use. Since the probe
is equipped with an in-place calibration
feature, provision should be made for con-
necting calibration gas tanks to the oxygen
analyzer when the probe is to be calibrated.
If the calibration gas bottles will be perma-
nently hooked up, a check valve is required
next to the calibration fittings on the probe
junction box. This is to prevent breathing of
calibration gas line and subsequent flue gas
condensation and corrosion. The check
valve is in addition to the stop valve in the
calibration gas kit or the solenoid valve in
the multiprobe calibration gas sequencer
units.
An optional Z-purge arrangement is avail-
able for applications where hazardous area
classification may be required (See Appli-
cation Data Bulletin AD 106-300B).
