Yes, they connect to any LoRaWAN or MQTT infrastructure (Kerlink, Cisco, Milesight, MultiTech, etc.) for flexible integration with existing SCADA systems.
LNG Cryogenic Temperature Monitoring
Thermal deviation tracking and insulation performance visibility
Temperature
Quick Overview
| Problem | Temperature deviations in cryogenic systems can occur locally and are not always continuously monitored at critical points. |
| Solution | SENSAiO temperature sensors monitor cryogenic temperature conditions across LNG systems in real time. |
| Value | Improved visibility on thermal behavior, supporting earlier detection of abnormal temperature variations. |
| ATEX | Suitable for LNG hazardous environments (Zone 1–2), compliant with ATEX / IECEx requirements. |
The Operational Challenge
LNG systems operate at cryogenic temperatures, typically around -160°C, to maintain natural gas in liquid form.
Maintaining stable temperature conditions is essential for:
- Preserving LNG phase state
- Preventing excessive boil-off gas generation
- Ensuring equipment integrity
Temperature deviations may arise from:
- Heat ingress through insulation degradation
- Flow disturbances inside pipelines or equipment
- Operational transients during loading or unloading
- Inadequate cooling or circulation
From a physical perspective, temperature changes may lead to:
- Partial vaporization of LNG (boil-off gas formation)
- Changes in fluid density and flow behavior
- Thermal stress on materials because of expansion or contraction
Detection challenges include:
- Cryogenic systems distributed across large facilities
- Limited instrumentation at certain points
- Localized temperature changes that are not captured by central measurements
- Intermittent manual inspection
As a result, temperature anomalies may develop without immediate detection.
Why Temperature Monitoring Matters
Temperature is a direct and fundamental parameter in cryogenic systems.
By continuously monitoring temperature:
- Baseline cryogenic conditions can be established
- Deviations from expected temperature ranges can be detected
- Trends can be analyzed over time
Typical interpretations include:
- A temperature increase may indicate heat ingress or reduced insulation performance
- Localized temperature rise may correlate with flow disturbance or partial vaporization
- Temperature instability may reflect operational transients
Temperature data provides a direct indication of system thermal behavior.
SENSAiO Solution
SENSAiO deploys wireless temperature sensors installed on LNG pipelines, storage systems, or process equipment.
Sensors continuously measure temperature and transmit data via LoRaWAN to a centralized monitoring platform.
The system provides:
- Continuous temperature trend monitoring
- Detection of abnormal temperature deviations
- Alerts based on thresholds or unusual patterns
It is important to clarify that:
- SENSAiO is a monitoring-only system
- It does not control cooling systems or LNG processes
- It does not calculate boil-off rates automatically
- It does not replace process control or safety systems
The system supports operational awareness and investigation.
Results and ROI
ATEX Compliance and Safety
LNG facilities are hazardous environments due to the presence of flammable gas. SENSAiO sensors:
- Are available with ATEX / IECEx certification for Zone 1–2
- Are designed for cryogenic temperature conditions
- Can be installed on pipelines and equipment handling LNG
All equipment is delivered with appropriate certification documentation.
SENSAiO systems are not safety systems and do not replace cryogenic protection 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 LNG monitoring and maintenance platforms |
| Deployment | Suitable for retrofit on existing LNG 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.
