Introduction

GB/T 18403 in this section include a high temperature electrochemical oxygen sensor characteristic analyzer terminology, performance specifications and tests.

Use of a high temperature electrochemical oxygen analyzer sensor, the operating temperature is typically in excess of 600 deg.] C, measured for the oxygen content of the gas sample has a very Wide measuring range. Gas to be measured in a representative sample is the product of the combustion process.

There are two types of on-line analyzer An in situ type analyzer that the sensor is installed in the gas path; the other is the sample Type analyzer sample through simple sampling system to the sensor.

A typical online analyzer comprises two parts mounted on the control unit and the sensor cable inside the gas line connection.

Performance of gas analyzers - Part 2.

Gas oxygen (high-temperature electrochemical sensors)

1 Scope

GB/T 18403 in this section apply to the use of high-temperature electrochemical sensor to measure various types of oxygen in the gas analyzer, and with GB/T 18403.1-2001 combination.

This section applies to in-situ and extractive analyzers formula parser and analyzer installed in the indoor and outdoor.

The purpose of this section is.

--- Provisions concerning the gas analyzer features terms and definitions, the analyzer utilizing high-temperature electrochemical sensors continuously measure the oxygen concentration in the sample gas;

--- Unified class analyzer features and verification methods;

--- Specifies the test content and test methods for determination of functional characteristics should be carried out;

--- Provide basic document for the ISO 9001, ISO 9002 and ISO 9003 quality management standard applications.
