Oxy-Orbital Bench Mounted Oxygen Analysers for TIG Welding

The OXY-Orbital Oxygen bench mounted indicator from Orbitec Ltd incorporates a maintenance-free ceramic sensor, which can accurately measure rest oxygen levels as small as 1 ppm (part per million) volume. Oxygen indicators with readout capabilities of only 0.1% (1000 ppm) or 0.01% (100 ppm) are not suitable for the welding industry as most precision welding is done below 70 ppm. This ceramic sensor is housed in a robust housing and is designed for job site as well as clean room work using a 110V / 220V connection. The unit can fitted with impulse that can be used in conjunction with an orbital welding machine.

The OXY-Orbital is designed to process the output from an oxygen sensor made of stabilized zirconium oxide. This material is a ceramic, also known as a solid electrolyte and 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-Orbital 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 computation is done to give an accurate reading. Maintenance and calibration-free make this the premium choice in oxygen analyzing.
