Oxy-2 oxygen indicator - purge welding gas sensor
The OXY-2 Oxygen Indicator incorporates a maintenance-free, non-depleting
ceramic sensor, which can accurately measure rest oxygen levels as small as
1ppm (part per million) volume. Oxygen indicators with readout capabilities of
only 0.1% (1000ppm) or 0.01% (100ppm) are not suitable for the welding
industry as most precision welding is done below 70ppm. The OXY-2
Oxygen Indicator incorportaes a ceramic sensor located in a robust housing
and is designed for demanding application from, construction job site's to
clean rooms. The machine uses a standard 110v connection (220v available
upon request). The unit can be fitted with an optional impulse to be used in
conjunction with an orbital welding machine.
The OXY-2 is designed to process the output from an oxygen sensor made of
stable zirconium oxide. This ceramic material, (also known as a solid
electrolyte) is ideally suited to high-temperatures like those used as an oxygen
ion conductor. Such ion conductors whose temperature range is dependent on
the composition of the material, possess the capability to fill empty spaces in
their crystal structure with oxygen ions. The oxygen ions attach themselves to
conductive platinum surfaces. The degree of oxygen concentration in gas
determines the degree of oxygen activity and thus, the quantity of oxygen ions.
The OXY-2 sensor consists of a solid electrolyte, which is exposed to gas on
both sides. One side is in contact with a reference gas - air - the other with
the - gas - to be measured. Using both heated and unheated sensors a |
With no maintenance -or- calibration needed, the OXY-2 Oxygen Indicator is
the premium choice in oxygen analyzers.
