The PTSenR™ LS300 LiGuard BESS Active Thermal Detector (Cluster) is an advanced active
thermal hazard monitoring device engineered for ultra-early detection of risks in Battery Energy
Storage Systems (BESS). Designed to safeguard critical energy infrastructure, the LS300
combines nano-particle detection, characteristic gas monitoring, and active online sampling to
deliver precise, real-time warnings of overheating, discharge, and potential thermal runaway
events. Its detection principle is based on Mie scattering technology, which enables accurate
identification of microscopic particles released during the early stages of equipment or material
overheating. When a beam of light irradiates these particles—typically ranging from 0.002 μm to
0.05 μm—the light scatters in all directions.
By analyzing the scattering parameters, the LS300 determines particle size and concentration
with exceptional precision. This process, fully aligned with Mie scattering theory, is enhanced by
intelligent algorithms that quantify particle density and detect abnormal trends long before visible
smoke or gas escalation occurs. Through this integration of optical physics and smart analytics,
the LS300 provides a robust, multi-parameter monitoring solution that ensures comprehensive
protection and proactive risk management in modern energy storage environments.
