c. System Configuration
The equipment covered in this manual con-
sists of three major components: the oxy-
gen analyzer (probe), the intelligent field
transmitter (IFT), and an optional heater
power supply (HPS). The HPS is required
where the cable run between the probe and
the electronics is greater than 150 ft (45 m).
There is also an optional multiprobe calibra-
tion gas sequencer (MPS) to facilitate
automatic calibration of the probe.
Probes are available in five length options,
giving the user the flexibility to use an in situ
penetration appropriate to the size of the
stack or duct. The options on length are 18
in. (457 mm), 3 ft (0.91 m), 6 ft (1.83 m), 9 ft
(2.7 m), or 12 ft (3.66 m).
The IFT contains electronics that control
probe temperature (in conjunction with the
optional HPS), supply power, and provide
isolated outputs that are proportional to the
measured oxygen concentration. The oxy-
gen sensing cell is maintained at a constant
temperature by modulating the duty cycle of
the probe heater. The IFT accepts millivolt
signals generated by the sensing cell and
produces outputs to be used by remotely
connected devices. The IFT output is iso-
lated and selectable to provide linearized
voltage or current.
The heater power supply (HPS) can provide
an interface between the IFT and the probe.
The HPS contains a transformer for sup-
plying proper voltage to the probe heater.
The enclosure has been designed to meet
NEMA 4X (IP56) specifications for water
tightness; an optional enclosure to meet
Class 1, Division 1, Group B (IP56) explo-
sion proof is also available.
Systems with multiprobe and multiple IFT
applications may employ an optional MPS
3000 Multiprobe Calibration Gas Se-
quencer. The MPS 3000 provides automatic
calibration gas sequencing for up to four
probes and IFTs to accommodate automatic
calibration.
d. System Features
1. Unique and patented electronic cell
protection action that automatically
protects sensor cell when the analyzer
detects reducing atmospheres.
2. Output voltage and sensitivity increase
as the oxygen concentration
decreases.
3. User friendly, menu driven operator
interface with context-sensitive on-line
help.
4. Field replaceable cell.
5. Analyzer constructed of rugged 316
LSS for all wetted parts.
6. The intelligent field transmitter (IFT)
can be located up to 150 ft (45 m) from
the probe when used without optional
heater power supply (HPS). When the
system includes the optional HPS, the
HPS can be located up to 150 ft (45 m)
from the probe and the IFT may be lo-
cated up to 1200 ft (364 m) from the
HPS.
7. All electronic modules are adaptable to
100, 120, 220, and 240 line voltages.
8. Five languages may be selected for
use with the Intelligent Field
Transmitter:
English Italian
French Spanish
