Hydrogen Storage Overpressure Monitoring (Safety-Critical Tanks) — ATEX
Prevents accidents
Pressure
Quick Overview
| Problem | Hydrogen storage tanks operate under high pressure with very low tolerance for deviation. Overpressure, pressure cycling, or undetected micro-leaks can lead to safety incidents, forced shutdowns, or regulatory non-compliance in ATEX-classified environments. |
| Solution | Sensa.io’s ATEX-certified pressure sensors provide continuous, real-time monitoring of hydrogen storage pressure, enabling early detection of abnormal conditions and safe control of storage systems. |
| Value | Improved storage safety • Reduced risk of shutdowns • Compliance assurance • Predictable operations |
| ATEX | Zones 0–2 • Ex ia IIC T4 Gb certified pressure sensors for hydrogen service |
The Operational Challenge
Hydrogen storage systems are used across multiple renewable energy applications, including:
- On-site hydrogen buffers for electrolysers
- High-pressure storage vessels for distribution
- Intermediate storage for mobility or grid injection
- Pilot and demonstration hydrogen hubs
These systems are exposed to:
- Rapid pressure variations during charging and discharging
- Temperature-driven pressure changes
- Material fatigue from pressure cycling
- Extremely low leak tolerance due to hydrogen’s properties
Common operational risks include:
- Progressive pressure rise caused by thermal effects
- Undetected pressure decay indicating micro-leaks
- Inadequate visibility between manual inspections
- Limited instrumentation due to ATEX constraints
Traditional monitoring often relies on:
- Mechanical pressure gauges
- Safety relief devices only
- Periodic manual checks
This approach provides no early warning before safety thresholds are reached.
Why Continuous Pressure Monitoring Matters
Pressure is the primary safety parameter for hydrogen storage.
Continuous monitoring enables operators to:
- Detect abnormal pressure rise before relief activation
- Identify pressure decay patterns indicating leakage
- Monitor pressure cycling stress on storage vessels
- Correlate pressure behaviour with temperature and operating cycles
Early detection is essential to avoid escalation into emergency shutdowns, safety incidents, or regulatory reporting.

FAQ - Common Questions
Are Sensa.io sensors compatible with any gateway or network?
What ATEX certifications apply to Sensa.io devices?
All hazardous-area models are certified Ex II 2 G Ex ia IIC T4 Gb and IECEx approved for Zones 0–2.
What is the typical battery life?
Up to 10 years at 15-minute intervals, depending on signal strength and environment.
How are the sensors integrated into existing systems?
Through standard protocols — LoRaWAN, Modbus, MQTT, REST API — no proprietary middleware needed.
How does predictive maintenance reduce OPEX?
Early anomaly detection reduces emergency interventions by 30–40 %, extends equipment life and lowers energy costs.
What does the Sensa.io Valve Position Sensor actually measure?
The device detects real-time valve position states—open, closed, or intermediate—with high accuracy. It continuously sends this information wirelessly to your monitoring dashboard.
Can this sensor detect partial valve movement or stuck valves?
Yes. The sensor identifies irregular patterns such as partial movement, delayed response, or stuck valves, enabling early maintenance before failure occurs.
Is this sensor suitable for manual, motorized, and actuated valves?
Yes. It supports a wide range of valve types including ball, gate, butterfly, actuator-driven, and manual valves.
How fast does it update the valve position?
You can configure the reporting interval—from seconds to minutes—depending on your operational and battery needs.
How long does installation take?
Most installations take under 10 minutes. The sensor mounts using brackets or clamps without modifying existing valves.
