Transmitter
The sensor core contains all the active components of the analyzer. They
include:
1. the diffusion element filter at the end of the probe
2. the ZrO
2
sensing cell
3. the heater to heat the cell
4. a type K thermocouple
5. ceramic insulated wires for carrying the T/C and Cell signals,
6. transmitter electronics to control the heater and condition the raw mV
probe signals to a linear 4-20 mA O2 signal for use in the user's control
or data acquisition system.
Operator interface for setup, calibration, indication, and diagnostics is
available by several means:
1. HART communications through a 375 Field Communicator
2. HART communications through Emerson's AMS
3. An optional Xi Enhanced Interface. The Xi can act as interface to one or
two X-STREAM probes. The Xi also carries advanced features such as
elevated process temperature capability, autocalibration via an SPS
solenoid box, a stoichiometer feature for indicating the level of oxygen
deficiency in reducing conditions, and programmable reference to
enhance accuracy at near ambient levels of O

INSTALLATION
SUMMARY
Probe Mounting -
A standard 6-inch square weld plate with a 2-½ inch NPT
probe port must be welded to the duct wall. Optionally,
a traditional stud plate
to accept a 150# ANSI flange must be welded to the duct wall. See the
drawings in Section 2: Installation.
Xi Mounting
- Pipe, wall, or panel mount.
Reference Air -
Ferrule fittings for ¼" tubing. Reference air should be clean,
dry instrument air regulated to 5 psi (34 kPa) minimum, 8 psi (54 kPa)
maximum, and a flow of 0.5 scfh (0,25
/hr) maximum.
Calibration Gas -
Ferrule fittings for ¼" tubing. If cal gas lines are
permanently connected, a check or blocking valve should be used at the
probe to ensure that flue gases do not flow back through the lines.
Heater Power -
100-240 VAC, 50/60 Hz ±10%, via ½-inch NPT conduit port.
Transmitter Electronics (without Xi) -
"Loop powered" from the control
room by the 4-20 mA signal.
Transmitter Electronics with Optional Xi -
100-240 VAC, 50/60 Hz
±
10%,
via ½-inch bulkhead fitting.
A 4-20mA signal from transmitter is powered from the Xi.
A 4-20 mA signal to the control room can be loop-powered from
the control room or from the Xi.
