[Electrochemical oxygen analyzer with automatic temperature compensation]
Abstract:
A meter of oxygen partial pressure in gaseous medium capable of working in operating conditions has been designed. A circuit of temperature compensation for a pO2-probe current is described which is built on a functional division converter. The probe design and the electronic unit are also presented. With the new analyzer the results of O2 measurements differ no more than 3% from those obtained by using Holden analyzer. Temperature measurements have shown an additional error to be at least 2,5% within the temperature range of 5 degrees C to 50 degrees C.
