Previously, Aerospace Yilian has been conducting four years of TDLAS technology research and development, with relevant foundations. In June 2016, it began to evaluate the results of high-precision TDLAS humidity measurement technology. The laser pointer technology has reached international advanced level. Li Gang, the person in charge of the company, made a detailed report on the research background, goals, research content, technical route, scientific research team and research foundation, expected results, and project research cycle in the report.
According to him, the project team will make breakthroughs around key issues such as measuring high ambient humidity, many interference factors in working conditions (corrosive gas, static electricity, smoke, dust, droplets, etc.), lack of high temperature and high humidity calibration technology, and device reliability under severe conditions. Humidity large dynamic range adaptive measurement technology, complex operating conditions multi-wavelength measurement and control technology, and laser temperature and current control technology. Developed a laser high-temperature humidity sensor with a working temperature of 20 ° C ~ 350 ° C, and carried out demonstration applications to improve and optimize it. The purpose of real-time measurement of high temperature and humidity such as exhaust gas and boiler steam is to realize the final production and industrialization of sensors.
Technical expert groups from environmental monitoring, radio, instrumentation and other related fields and user committees composed of users in the power, environmental protection, aerospace, petrochemical and other industries listened to the project team’s report and made relevant suggestions for the product demonstration application stage. High temperature and humidity measurement is so important, but the realization of its green laser pointer technology is very difficult. Because of this, the project was approved in August this year by the Ministry of Science and Technology for a major scientific instrument and equipment development application. Once the sensor is successfully developed, it can improve the monitoring level of high temperature and humidity, improve the accuracy of environmental protection emission measurement, and save energy and reduce emissions in industrial processes.
