MF010-O-LC dynamic oxygen measuring system

The MF010-O-LC dynamic oxygen measuring system provides a fail-safe way to determine the residual oxygen content in furnace exhaust gas. With the help of a coupled controller the excess air specified for reasons of safety can be minimised and combustion in the furnace optimised, thereby increasing efficiency. In this way it is possible to compensate for fluctuations in the quality of fuels for modern wood firing. Contrary to a lambda probe which measures the relative oxygen content, this robust oxygen measuring system determines the absolute content. For this reason, fluctuations in air pressure, humidity and temperature have no influence on the accuracy of the measurement. The system is calibrated electrically, without reference gas and without additional personnel, in atmospheric air at the end of the furnace’s ventilation phase, thereby reducing maintenance work. Measuring range is from 0.1 to25% by vol. oxygen at an exhaust gas temperature of up to 250°C.
