1-2 Features and Capabilities
Basic Features (cont.) • At high oxygen concentrations, changes in atmospheric pressure
have significant effects on the measured oxygen level. However,
the XMO2 provides automatic microprocessor-based atmospheric
pressure compensation of the oxygen signal for these applications.
• The XMO2’s modular construction means that the unit can be
field-calibrated quickly and easily. Also, the plug-in measuring cell
can be replaced with a pre-calibrated spare in just minutes.
• The XMO2 Transmitter, which is available in weatherproof or
explosion-proof packaging, is designed to be installed as close as
possible to the process sample point. It can be located up to 450 ft
(137 m) from the control system, display, or recorder using
standard GE cables.
• An RS232 serial communications interface and a multi-level,
menu-driven User Program provide a convenient means for
calibrating and programming the XMO2
• Internal software algorithms along with user-programmed
calibration data provide compensation of the oxygen signal for
background gas composition, atmospheric pressure, or both
background gas composition and atmospheric pressure.
• GE’s proprietary Fast-Response software provides enhanced
response times to track rapidly changing processes.
• Sophisticated error-checking software with user-programmable
defaults and error limits detects abnormal measurement conditions.
• Pushbutton adjustment of the 4-20 mA analog output zero and
span values is a standard feature with the XMO2.
• A drift calibration routine provides automatic drift compensation
for minor changes in the sensor calibration setting.
• Programmable recalibration is accomplished in the field via a
computer interface, with no potentiometers to adjust.
