PGS5100 Hydrogen Sensor
Posifa’s PGS5100 Series hydrogen sensors enable fast, reliable detection of hydrogen in safety-critical environments such as EV battery packs, fuel cell systems, and industrial facilities. The sensors measure hydrogen concentrations from 0 % to 25 % using MEMS thermal conductivity technology.
Integrated humidity and barometric pressure sensors automatically compensate for environmental variations, helping maintain measurement accuracy across temperature, humidity, and altitude changes. Designed for embedded monitoring systems, PGS5100 sensors combine fast response, long service life, and robust operation in harsh environments.
Optimized for EV Battery Safety and Thermal Runaway Detection
Hydrogen can appear during the early off-gas stage of certain battery events, before heat escalation and ignition occur. Detecting hydrogen at this stage can provide an early indicator of thermal runaway development in EV battery systems and allow mitigation systems to respond sooner.
Key Benefits for Hydrogen Monitoring Systems
- Detect hydrogen leaks early in safety-critical environments
- Enable earlier response to EV battery off-gas events
- Maintain accuracy with humidity and pressure compensation
- Deliver reliable long-term operation in harsh conditions
- Support robust automotive and industrial system integration
Key performance characteristics include
- Fast response for real-time hydrogen monitoring
- Long-term stability with operating life exceeding 15 years
- Non-reactive sensing technology resistant to contaminants
- Reliable operation in harsh environmental conditions
Lithium-ion battery failures often begin with a phase of electrolyte decomposition and gas generation before heat escalation and ignition occur. During this early stage, hydrogen may be released inside the battery enclosure before visible signs of failure appear.
By detecting hydrogen during this initial off-gas phase, monitoring systems can identify abnormal battery conditions earlier and trigger mitigation actions such as system shutdown, isolation, or ventilation.
PGS5100 hydrogen sensors enable this type of early warning by providing:
- Fast response for real-time gas monitoring
- Stable operation inside enclosed battery pack environments
- Long service life suited for vehicle lifetime requirements
- Reliable detection without catalytic sensing elements
These capabilities make the PGS5100 well suited for EV battery safety systems, battery energy storage systems, and other lithium-ion battery monitoring applications.
