Control at the tip of a finger

The oxy.IQ is a highly reliable and cost-effective two-wire,loop-powered transmitter with a linearized 4 to 20 mA
output. It measures oxygen in ten ppm ranges and six
percentage ranges. All ranges are user-selectable. This
compact transmitter uses proven sensor technology
to accurately measure O2 in a variety of gases, even inhazardous environments.

The rugged oxy.IQ is controlled by a microprocessor thatenables the user to select the range, trim outputs andperform calibration. Improved user interface includes userselectable and programmable ranges, sensor diagnostics
including a sensor lifetime feature and sensor raw signal,
low reading/sensor failure signal and temperaturecompensation. Programming is easily done using thekeypad 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.

Proven sensor technology
The oxy.IQ’s oxygen sensor is an advanced galvanic fuel cellthat provides superior performance, accuracy, stability andlong life. The cell’s innovative design eliminates the potential
for negative signal output, reduces sources of contamination.
The cell is unaffected by other background gases orhydrocarbons and is compatible with acid gases(OX-2 andOX-4 cells). Recovery from air at low ppm levels takes justa few minutes. Because the cell is self-contained, minimal
maintenance is required. There is no electrolyte to change orelectrodes to clean.

Intrinsically safe
When equipped with optional zener barriers or a galvanic
isolator, the oxy.IQ can be mounted in a hazardous(classified) location.

Installation flexibility
The compact oxy.IQ, with its built-in microprocessor, isdesigned to fit easily into any installation site. The oxy.IQ
can be installed right at the sampling point, whereas othertransmitters must be rack or panel mounted.

Sample systems
In addition to standard features and options, Panametrics
offers a full line of sample handling systems for a variety ofapplications. If needed, Panametrics can design and build
a sample conditioning system to meet unique applicationrequirements. Please contact Panametrics for details.

Intrinsically safe (IS) installation

Intrinsically safe installations require a zener barrier, one IS
cable and one non-IS cable.

Power requirements
24 to 28 VDC at 50 mA

Cable

PN 704-1318: blue jacket, twisted pair with connector; 26 AWG;
