Yes, they connect to any LoRaWAN or MQTT infrastructure (Kerlink, Cisco, Milesight, MultiTech, etc.) for flexible integration with existing SCADA systems.
Solvent Tank Pressure & Temperature Monitoring (Storage Safety & Compliance) — ATEX
Prevents overpressure & explosions
Pressure
Temperature
Quick Overview
| Problem | Solvent storage tanks are exposed to pressure build-up, temperature variation, and vapour formation. Undetected overpressure, thermal expansion, or abnormal conditions can lead to venting events, fugitive emissions, tank deformation, or explosion risk—especially in ATEX-classified environments. Manual inspections provide limited visibility and expose personnel to hazards. |
| Solution | Sensa.io’s ATEX-certified pressure and temperature sensors continuously monitor solvent tanks to detect abnormal conditions early, ensuring safe storage, regulatory compliance, and loss prevention. |
| Value | Improved storage safety • Reduced solvent losses • Regulatory compliance • Lower inspection effort |
| ATEX | Zones 0–2 • Ex ia IIC T4 Gb certified pressure & temperature sensors |
The Operational Challenge
Solvent tanks are used across chemical industries for:
- Raw material storage
- Intermediate buffer tanks
- Finished product storage
- Waste and recovery solvents
They face multiple operational risks:
- Thermal expansion during temperature changes
- Vapour pressure increase from volatile solvents
- Blocked or malfunctioning vents
- Overfilling or abnormal operating conditions
Typical monitoring limitations include:
- Manual gauge readings
- Infrequent inspection rounds
- Limited instrumentation on legacy tanks
- Reactive response after alarms or incidents
Consequences of inadequate monitoring can include:
- Continuous venting and solvent loss
- Emission threshold exceedance
- Structural stress on tanks
- Safety incidents and regulatory non-compliance
Why Continuous Pressure & Temperature Monitoring Matters
Pressure and temperature are the primary indicators of safe solvent storage.
Continuous monitoring enables operators to:
- Detect overpressure before venting occurs
- Identify abnormal thermal behaviour
- Verify proper vent and relief operation
- Maintain stable storage conditions
Early detection prevents loss events and supports safe ATEX operations.

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.
