Description of Equipment:
The Model oxy.IQ is a two-wire, loop-powered transmitter for measuring oxygen in ten ppm ranges and
seven percentage ranges. The Model oxy.IQ Transmitter contains one of five different oxygen cells. The
cells are specified to be part numbers OX-1, OX-2, OX-3 and OX-4 and OX-5. The type of oxygen cell
determines the range of measurement. The measured oxygen is converted to a mA signal for delivery to the
control equipment located in the non-hazardous area.
The Model oxy.IQ Transmitter's electronics are contained on one printed circuit board. The circuit board is
located inside of a metallic housing. An oxygen cell holder is connected to the circuit board by way of pins.
The base of the oxygen cell holder contains a threaded joint for replacement of the oxygen cell. The
housing contains a polymeric window display. The polymeric window is approximately 1" by ¾".The housing,
including the sensor assembly, is approximately 4.1" in height, by 2.75" in width, and 2.05" in depth.
Operation Temperature Ranges:
The ambient operating temperature range of the Model oxy.IQ Transmitter is -20°C to +60˚C.
The Transmitter is specified for use in normal atmospheric conditions.
Intrinsically Safe Energy Limitation Parameters:
Ui = 28V, Ii = 150mA, Pi = = 1.05W, Ci = 0, Li =
Model oxy.IQ-a3b-c0. Oxygen Transmitter.
a = Sensor: 0, 1, 2, 3, 4 or 5.
b = Cable Length: 0, 1 or 2.
c = Barrier: 0, 1 or 2.
Specific Conditions of Use:
1. The Model oxy.IQ Oxygen Transmitter will not pass the 500Vrms dielectric strength test. This must be
taken into account during installation.
2. When installed in a Division 2 location, the Model oxy.IQ Oxygen Transmitter shall be installed in a final
enclosure accepting a Division 2 wiring method per the NEC.
Test and Assessment Procedure and Conditions:
