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.

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.

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-

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:
