Yes, they connect to any LoRaWAN or MQTT infrastructure (Kerlink, Cisco, Milesight, MultiTech, etc.) for flexible integration with existing SCADA systems.
Hydrogen Storage Overpressure Monitoring
Improved event visibility and investigation support
Pressure
Quick Overview
| Problem | Pressure conditions in hydrogen storage systems are not always continuously monitored at all points, limiting visibility on abnormal pressure buildup. |
| Solution | SENSAiO pressure sensors provide continuous monitoring of storage pressure levels. |
| Value | Improved visibility on pressure behavior, supporting earlier detection of abnormal pressure increase or deviation from expected conditions. |
| ATEX | Designed for hydrogen environments, compliant with ATEX / IECEx requirements for explosive gas atmospheres. |
The Operational Challenge
Hydrogen storage systems (tanks, vessels, or buffer systems) are used to:
- Store compressed or processed hydrogen
- Balance supply and demand
- Maintain operational continuity
These systems operate under controlled pressure conditions.
From a physical perspective:
- Pressure represents the stored energy within the gas volume
- Variations in temperature or gas inflow/outflow directly affect pressure
- Overpressure conditions may develop if gas accumulates faster than it is released
Typical issues include:
- Pressure increase due to inflow imbalance
- Malfunctioning pressure relief or control devices
- Thermal effects causing pressure rise
- Blockage or restriction in downstream lines
Detection challenges include:
- Limited instrumentation at distributed storage points
- Lack of continuous monitoring in auxiliary systems
- Dependence on local gauges or periodic checks
- Difficulty identifying gradual pressure drift
As a result, abnormal pressure buildup may not be immediately detected.
Why Pressure Monitoring Matters
Pressure is a fundamental parameter in hydrogen storage systems.
By continuously monitoring pressure:
- Storage conditions can be tracked in real time
- Deviations from expected operating ranges can be identified
- Trends indicating gradual pressure increase can be observed
Typical interpretations include:
- Increasing pressure may indicate accumulation or restriction
- Sudden pressure rise may correlate with process imbalance
- Stable but elevated pressure may indicate system constraint
Pressure data reflects the balance between gas inflow, outflow, and storage conditions.
SENSAiO Solution
SENSAiO deploys wireless pressure sensors installed on:
- Storage tanks
- Buffer vessels
- Associated pipeline connections
Sensors measure pressure and transmit data via LoRaWAN to a centralized monitoring platform.
The system provides:
- Continuous pressure monitoring
- Trend analysis and historical tracking
- Alerts on abnormal pressure deviations
It is important to clarify that:
- SENSAiO is a monitoring-only system
- It does not control pressure relief systems
- It does not regulate storage conditions
- It does not replace safety systems such as relief valves or shutdown systems
The system supports operational awareness and early investigation.
Results and ROI
ATEX Compliance and Safety
Hydrogen storage areas are classified hazardous due to flammable gas presence. SENSAiO sensors:
- Are available with ATEX / IECEx certification for gas zones
- Are suitable for hydrogen storage environments
- Are designed for industrial hazardous areas
All equipment is delivered with appropriate certification documentation.
SENSAiO systems are not safety systems and do not replace pressure relief devices, emergency shutdown systems, or regulatory safety requirements.
Integration and compatibility
| Protocols | LoRaWAN, MQTT, REST API |
| Gateways | Compatible with standard LoRaWAN gateways (Kerlink, Multitech, Cisco, etc.) |
| Systems | Integration with hydrogen monitoring and maintenance platforms |
| Deployment | Suitable for retrofit on storage vessels and associated systems |
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.
