1.4 Features
The
oxy.IQ
oxygen sensor uses 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 and reduces sources of contamination.
The cell is unaffected by other background gases or hydrocarbons
and is compatible with acidic 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 and no electrodes to clean.
The
oxy.IQ
offers the following features:
•
Two-wire, loop-powered, 4 to 20 mA transmitter
•
Display with keypad
•
Intrinsically-safe option
•
Proven galvanic fuel cell O
