Panametrics Oxygen Transmitter
Control at the Tip of a Finger
The oxy.IQ is a highly reliable and cost-eective two-wire,
loop-powered transmitter with a linearized
4 to 20 mA output. It measures oxygen in ten ppm ranges
and seven percentage ranges. All ranges are userselectable. This compact transmitter uses proven sensor
technology to accurately measure O2 in a variety of gases,
even in hazardous environments.
Proven Sensor Technology
The oxy.IQ’s oxygen sensor is an advanced galvanic
fuel cell that provides superior performance, accuracy,
stability and long life. The cell’s innovative design
eliminates the potential for negative signal output,
reduces sources of contamination.
The cell is unaected by other background gases or
hydrocarbons and is compatible with acid gases
(OX-2 and OX-4 cells). Recovery from air at low ppm levels
takes just a few minutes. Because the cell is
self-contained, minimal maintenance is required. There is
no electrolyte to change or electrodes to clean.
Intrinsically Safe
When equipped with optional zener barriers or a galvanic
isolator, the oxy.IQ can be mounted in a hazardous
(classied) location.
The rugged oxy.IQ is controlled by a microprocessor that
enables the user to select the range, trim outputs and
perform calibration. Improved user interface includes
user-selectable and programmable ranges, sensor
diagnostics including a sensor lifetime feature and
sensor raw signal, low reading/sensor failure signal and
temperature compensation. Programming is easily done
using the keypad and display. These keypad buttons allow
complete functionality in hazardous areas when equipped
with a zener barrier or a galvanic isolator per drawing
752-347.
Installation Flexibility
The compact oxy.IQ, with its built-in microprocessor,
is designed to t easily into any installation site. The
oxy.IQ can be installed right at the sampling point,
whereas other transmitters must be rack or panel
mounted.
Sample Systems
In addition to standard features and options, GE oers
a full line of sample handling systems for a variety
of applications. If needed, GE can design and build a
sample conditioning system to meet unique application
requirements. Please contact GE for details.
