Yes, they connect to any LoRaWAN or MQTT infrastructure (Kerlink, Cisco, Milesight, MultiTech, etc.) for flexible integration with existing SCADA systems.
Hydrogen Compressor Vibration Monitoring
Hydrogen Compressor Vibration
Vibration
Quick Overview
| Problem | Hydrogen compressors operate under high mechanical and dynamic loads, and vibration behavior is not always continuously monitored across all units. |
| Solution | SENSAiO vibration sensors provide continuous monitoring of compressor vibration patterns. |
| Value | Improved visibility on mechanical condition, supporting earlier detection of abnormal operating behavior. |
| ATEX | Designed for hydrogen environments, compliant with ATEX / IECEx requirements for explosive gas atmospheres. |
The Operational Challenge
Hydrogen compressors are critical components used to:
- Increase gas pressure for storage or transport
- Maintain flow through hydrogen networks
- Feed downstream processes such as liquefaction or fueling
These compressors involve:
- High-speed rotating elements
- Bearings and seals under stress
- Compression stages generating thermal and mechanical loads
From a physical perspective:
- Rotating machinery generates vibration due to imbalance, friction, and dynamic forces
- Each compressor has a characteristic vibration signature during normal operation
- Mechanical degradation alters vibration amplitude and frequency content
Typical issues include:
- Bearing wear or lubrication degradation
- Rotor imbalance or misalignment
- Seal degradation
- Mechanical looseness or structural resonance
Detection challenges include:
- High-speed operation masking early-stage changes
- Limited instrumentation on distributed compressor assets
- Dependence on periodic inspections
- Difficulty detecting gradual degradation trends
As a result, abnormal mechanical conditions may develop without continuous monitoring.
Why Vibration Monitoring Matters
Vibration is a direct indicator of mechanical behavior in rotating equipment.
By continuously monitoring vibration:
- Baseline operating conditions can be established
- Deviations from normal vibration patterns can be detected
- Progressive mechanical changes can be tracked
Typical interpretations include:
- Increasing vibration amplitude may indicate wear or imbalance
- Changes in vibration frequency may correlate with mechanical faults
- Intermittent vibration spikes may indicate transient or unstable conditions
Vibration data reflects how mechanical energy is distributed within the compressor.
SENSAiO Solution
SENSAiO deploys wireless vibration sensors installed on:
- Compressor housings
- Bearing points
- Structural frames
Sensors capture vibration signals and transmit data via LoRaWAN to a centralized monitoring platform.
The system provides:
- Continuous vibration monitoring
- Trend analysis over time
- Alerts on abnormal vibration deviations
It is important to clarify that:
- SENSAiO is a monitoring-only system
- It does not perform automatic fault diagnosis
- It does not predict failures with certainty
- It does not replace compressor protection systems or safety controls
The system supports earlier investigation and maintenance planning.
Results and ROI
ATEX Compliance and Safety
Hydrogen compression systems operate in explosive gas atmospheres. SENSAiO sensors:
- Are available with ATEX / IECEx certification for gas zones
- Are suitable for hydrogen infrastructure
- Are designed for harsh industrial environments
All equipment is delivered with appropriate certification documentation.
SENSAiO systems are not safety systems and do not replace shutdown systems, gas detection, or regulatory safety protections.
Integration and compatibility
| Protocols | LoRaWAN, MQTT, REST API |
| Gateways | Compatible with standard LoRaWAN gateways (Kerlink, Multitech, Cisco, etc.) |
| Systems | Integration with maintenance and hydrogen monitoring platforms |
| Deployment | Suitable for retrofit on existing compressor installations |
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.
