Energy industry laser oxygen online analyzer

1、 Product Overview

Energy industry laser oxygen online analyzerAdopting tunable semiconductor laser absorption spectroscopy（TDLAS）Technology, based on Bill-Lambert's law enables real-time online monitoring of oxygen concentration in energy production processes. The equipment has strong anti-interference ability and fast response speed（≤1High measurement accuracy (in seconds)（±0.1%FS）These characteristics can be widely applied in combustion control, process optimization, and safety monitoring in fields such as thermal power, coal chemical industry, oil and gas extraction, biomass energy, etc.

2、 Core technological advantages

1. Spectral selective detectionUsing a specific wavelength laser（760nmThe nearby oxygen characteristic absorption line can effectively avoidH₂OTheCO₂TheCH₄Maintain measurement stability even under complex working conditions with the interference of background gases.

2. In situ analysis techniqueSupport direct insertion of laser probes into process pipelines (temperature)-40℃~800℃, pressure≤10MPa）No need for sampling preprocessing system, reducing lag error (typical response time<)0.5Seconds).

3. Multi parameter adaptive compensationBuilt in temperature, pressure, and humidity sensors are used to dynamically adjust the impact of environmental changes on measurement results in real time, ensuring accuracy is maintained during fluctuations in operating conditions (drift<0.05%FS/24h）.

4. Dust resistant designUsing sapphire windows+Automatic blowing device (optional nitrogen gas)/Compressed air blowback can be used to reduce dust concentration≤200g/m³Continuous operation in harsh environments, with maintenance cycles extended to6More than a month.
