Panametrics Oxygen Transmitter

Control at the Tip of a Finger

The O2X1 is a highly reliable and cost-eff ective two-wire,
loop-powered transmitter with a linearized 4 to 20 mA
output. It measures oxygen in four ppm ranges (10; 100;
1,000 and 10,000 ppm) and three percentage ranges (1,
10, and 25%). All ranges are user-programmable. This
compact transmitter uses proven sensor technology
to accurately measure O2 in a variety of gases, even in
hazardous environments.

Proven Sensor Technology

The O2X1’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 and eliminates
electrolyte leakage.

The cell is unaff ected 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,
little maintenance is required. There is no electrolyte to
change or electrodes to clean.

The rugged O2X1 is controlled by a microprocessor that
enables the user to select the range, trim outputs and
perform calibration. Programming is easily done using the
three-button keypad and the three light-emitting diodes
(LEDs). These switches allow complete functionality in
hazardous areas when equipped with an MTL706 barrier.

Installation Flexibility

The compact O2X1, with its built-in microprocessor, is
designed to fi t easily into any installation site. The O2X1
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 off ers
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.

Intrinsically Safe

When equipped with the optional MTL706 barriers, the
O2X1 can be mounted in a hazardous (classifi ed) location
as defi ned by the National Electrical Code (NEC). The
O2X1 316 stainless steel package is FM approved as
intrinsically safe for use in Class I, II, III; Division 1; Groups
A,B,C,D,E, F&G hazardous (indoor/outdoor) Type 4X
locations, and is certifi ed by BASEEFA II 1 G EEx ia IIC T4
(Tamb = –20°C to +60°C)
