Silicon Beam Sensing leverages its core technology accumulation in optics, sensors, and micromachining, based on the principle of TDLAS tunable diode laser absorption spectroscopy, and integrates innovative multi-wavelength collaborative detection technology to develop the XSJG-M3-L25 three-in-one laser gas sensor module, which can simultaneously and accurately measure the concentrations of ethylene (C2H4), acetylene (C2H2), and ethane (C2H6). 

This sensor module adopts a self-developed multi-optical-path integrated absorption cavity, paired with a highly stable distributed feedback laser and a highly sensitive photodetector, combined with precision circuits and intelligent data processing algorithms, achieving synchronous and interference-free measurement of multiple gas components. It features a built-in temperature and pressure dual-parameter compensation unit that can automatically correct the impact of environmental changes on measurement results; equipped with a low-power, high-performance processor, it balances measurement accuracy with the battery life requirements of portable devices, making it suitable for gas concentration monitoring in multiple scenarios.
