Overview
The laser gas analyzer of Sifang Instrument adopts TDLAS cross beam technology, effectively avoiding background gas interference and ensuring measurement accuracy. It has a high explosion-proof rating and a multi-stage filtration system, which can operate stably for a long time under harsh working conditions such as high dust and high corrosion, achieving automatic sampling and remote monitoring. Widely used in key safety and process control points such as coal powder silos, blast furnaces, converters, etc., to assist in safety production and energy efficiency improvement.
Product Details
Product Name:Laser gas analyzer
Product Model:GasTDL-3110
Product Introduction
Laser gas analyzerDesigned for high dust conditions in the sample gas, it consists of four parts: sampling probe, preprocessing unit, control unit, and gas analysis unit. The system adopts tunable semiconductor laser absorption spectroscopy technology (TDLAS) with a beam design, which can continuously reflect the measured gas concentration in real time, which is conducive to improving gas utilization efficiency, energy conservation and consumption reduction, and ensuring safe production in industrial sites.
Product Features
Explosion proof rating Ex db IIC T6 Gb/Ex tb IIIC T80 ℃ Db, high safety factor.
The probe has automatic blowing function, reliable performance, and long lifespan.
It can automatically complete sampling, blowback, drainage and other operations.
Multi level filtration ensures long-term online operation of the instrument.
Using TDLAS technology, the measured gas is not affected by background gas cross interference.
Remote monitoring can be achieved without the need for manual attendance, reducing maintenance costs.
It has good adaptability in harsh measurement environments such as high temperature, high dust, high moisture, high corrosiveness, and high flow rate.
