GSM5310 hydrogen leak detection sensor module & FLS310 thermal conductivity sensor
Hydrogen is Full of Promise — and Risk
Hydrogen is light. Clean. Abundant. And vital to the future of energy. But it’s also hard to handle.
- It leaks easily.
- You can’t see or smell it.
- It’s highly flammable — with a wide explosive range.
- It behaves very differently in confined spaces vs open air.
As the hydrogen economy grows, so do the risks…unless we address them head-on.
The GSM5310 Hydrogen Leak Detection Sensor Module is designed for leakage detection in hydrogen applications.
- Uses Flusso FLS310 thermal conductivity sensor
- Accuracy ± max (1000 ppm, 10% m.v.) across a temperature range of -40 – 85 ºC and humidity range of 0 – 40 g/m3
- Fast start up (<1 s) and response time (<4 s)
- High selectivity to hydrogen in humid air
- Very high immunity to poisoning
- CAN interface
- EvalKit available from FMG
The GSM5310 is an example of possible modules based around the FLS310. The FLS310 thermal conductivity sensor is suitable for high-volume consumer and industrial applications. Main features are:
- CMOS MEMS thermal conductivity technology
- Contains membrane crack detection circuit
- Ultra-small surface mount package (3×3 mm)
- Fully compatible with SMD assembly processes
Flusso is open to collaborate towards the development of customised sensor modules with FLS310 at their core.
