Flammable gas LEL concentration analyzer

SOLAREx seriesFlammable gas LEL concentration analyzerBy using flame temperature sensing (FTA) technology for direct measurement, it can respond to all combustible gases (including H2S, CO, H2, etc.) with a response time of less than 1 second. The combustion chamber of the analyzer has a precisely measured flame that continues to burn at a reference temperature. Samples containing flammable gases are drawn into the combustion chamber of the analyzer and burned in a hydrogen induced flame. The thermocouple located above the induction flame will measure the temperature changes caused by combustion in real time and convert the generated temperature rise into an electrical signal. The temperature rise is proportional to the 0-100% LEL concentration of combustible gas.

Analyzer Design

SOLAREx seriesFlammable gas LEL concentration analyzerIt is a highly integrated online LEL measuring instrument, equipped with a heating monitoring room and control unit, which can ensure that the analyzer continuously measures the low explosive limit of exhaust gas, with a measurement range of 0-100% LEL. Shigona Company adopts a unique measurement principle to design the LEL analyzer, which directly measures the combustible content in the sample to obtain LEL data, ensuring measurement accuracy and linearity.
