Yes, they connect to any LoRaWAN or MQTT infrastructure (Kerlink, Cisco, Milesight, MultiTech, etc.) for flexible integration with existing SCADA systems.
Solvent Line Pressure Monitoring
Early deviation visibility and improved process stability
Pressure
Quick Overview
| Problem | Pressure variations in solvent lines are not always continuously monitored, especially across distributed or secondary piping networks. |
| Solution | SENSAiO pressure sensors monitor solvent line pressure trends in real time. |
| Value | Improved visibility on hydraulic conditions, supporting earlier detection of abnormal pressure behavior. |
| ATEX | Suitable for hazardous chemical environments (Zone 1–2), compliant with ATEX / IECEx requirements. |
The Operational Challenge
Solvent lines are widely used in chemical and petrochemical processes for:
- Transporting liquid solvents between process units
- Feeding reactors or separation systems
- Supporting cleaning or extraction operations
These systems operate under varying flow and pressure conditions.
Pressure in solvent lines is influenced by:
- Flow rate changes
- Pump operation
- Valve positioning
- Fluid properties such as viscosity and temperature
From a physical perspective:
- Pressure reflects the balance between flow energy and system resistance
- Pressure losses occur due to friction, fittings, and equipment
- Changes in pressure indicate changes in flow behavior or system condition
Typical issues include:
- Partial blockages or fouling leading to pressure increase
- Leakage resulting in pressure drop
- Pump instability causing pressure fluctuations
- Incorrect valve positioning affecting flow distribution
Detection challenges include:
- Distributed piping networks across large plants
- Limited instrumentation on secondary lines
- Transient pressure events that are not captured
- Reliance on periodic manual checks
As a result, abnormal pressure conditions may not be identified early.
Why Pressure Monitoring Matters
Pressure is a key indicator of hydraulic performance in solvent systems.
By continuously monitoring pressure:
- Baseline operating conditions can be established
- Deviations from normal pressure ranges can be detected
- Pressure trends can be analyzed over time
Typical interpretations include:
- A gradual pressure increase may indicate restriction or fouling
- A pressure drop may correlate with leakage or reduced supply
- Pressure instability may reflect pump or control issues
Pressure data provides direct insight into solvent flow behavior.
Sensa.io Solution
SENSAiO deploys wireless pressure sensors installed along solvent lines or at critical points
Pressure visibility
such as:
- Upstream and downstream of pumps
- Near control valves
- At key process interfaces
Sensors continuously measure pressure and transmit data via LoRaWAN to a centralized monitoring platform.
The system provides:
- Continuous pressure trend monitoring
- Detection of abnormal pressure conditions
- Alerts based on thresholds or deviations
It is important to clarify that:
- SENSAiO is a monitoring-only system
- It does not control pumps or valves
- It does not perform flow calculation or leak confirmation
- It does not replace process control or safety systems
The system supports operational awareness and troubleshooting.
Results and ROI
ATEX Compliance and Safety
Solvent lines often carry flammable liquids and operate in hazardous zones. SENSAiO sensors:
- Are available with ATEX / IECEx certification for Zone 1–2
- Are suitable for installation on pressurized solvent lines
- Are designed for chemical processing environments
All equipment is delivered with appropriate certification documentation.
SENSAiO systems are not safety systems and do not replace pressure protection systems, leak detection systems, or regulatory safety requirements.
Integration and compatibility

| Gateways | Compatible with standard LoRaWAN gateways (Kerlink, Multitech, Cisco, etc.) |
| Systems | Integration with plant monitoring and maintenance platforms |
| Deployment | Suitable for retrofit on existing solvent piping networks |
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.
