Description

Principle of operation

The Buhler Model BA 1000 solid-state oxygen analyzer hasbeen developed for in-situ applications. The cell is selfcontrollingand therefore well- suited for applications in flue gas or similar matrices.

The dynamic sensor measures oxygen without using a reference gas. The sensor is consists of two zirconium discs covering both sides of a platinum ring. An additional Al O coating protects the sensor from environmental influence and increases it´s life expectancy. The measurement chamber (P2) is filled with a sample gas. One disc is connected with a reversible source of current. It is then used as an solid-state electronic oxygen pump. An optional pre-filter enables operation in gas streams with high dust concentrations.
