Li-ion Tamer LT-SEN-MOS Off-Gas Sensor Solution

LT-SEN-MOS designates the Li-ion Tamer Sensor Multi Output Solution (MOS), a plug-and-play lithium-ion battery monitoring assembly in the Li-ion Tamer gas detection range. Two primary components make up the solution, the LT-SEN-M off-gas sensor and the LT-SEN-IM-UL interface module, and the detection targets are hydrogen and battery electrolyte solvent vapours generated during thermal runaway, with fault detection at single cell failure level and a response time of 5 seconds.

Designed for modular Battery Energy Storage Systems (BESS), the assembly is compatible across lithium-ion battery form factors and chemistries. Placement puts the off-gas sensor at the battery racks or cabin, downstream of convective airstreams, with the interface module monitoring the sensor and integrating its output signals; two alarm relays are supported. Operation is calibration-free, needing only a bump test, and a companion variant, LT-SEN-MOS-C49, builds the same solution around the LT-SEN-M-C49 sensor.

Recognition of the off-gas sensor is to UL 2075 and ULC 588 for Hydrogen (H2), Carbon Monoxide (CO) and Battery Electrolyte Solvent Vapour detection, the vapour scope covering Diethyl Carbonate (DEC), Dimethyl Carbonate (DMC) and Ethyl Methyl Carbonate; the interface module holds fire alarm system module certification to UL864 10th. Related listings carry the Gen 2+ monitoring sensor as LT-SEN-M-L, and physical wiring and terminal connections are detailed in the installation manual.
