Seawater Cooling Pressure & Temperature Monitoring (Cooling Reliability & Asset Protection) — Offshore / ATEX
Ensures cooling reliability, uptime
Pressure
Temperature
Quick Overview
| Problem | Offshore seawater cooling systems are essential for heat removal across compressors, generators, and process units. Fouling, corrosion, leaks, or pump degradation often go undetected until cooling capacity is lost—leading to overheating, trips, and production loss in hazardous offshore environments. |
| Solution | SENSAiO’s wireless pressure and temperature sensors provide continuous monitoring of seawater cooling circuits, enabling early detection of fouling, leaks, and performance degradation. |
| Value | Improved cooling reliability • Reduced overheating risk • Lower maintenance OPEX • Increased asset availability |
| ATEX | Not always required on seawater lines; ATEX-certified pressure & temperature sensors available when installed in hazardous zones |
The Operational Challenge
Seawater cooling systems are widely used offshore for:
- Compressor and motor cooling
- Generator and turbine heat exchangers
- Lube oil and process cooling
- HVAC and utility cooling
These systems operate in extremely aggressive conditions:
- High salinity and corrosion
- Marine growth and biofouling
- Sand and suspended solids
- Continuous duty with limited redundancy
Common failure modes include:
- Progressive fouling of heat exchangers
- Cooling water leaks or pressure loss
- Pump wear reducing flow capacity
- Blocked strainers or filters
Traditional monitoring often relies on:
- Local gauges
- Periodic inspection
- Temperature alarms triggered too late
This results in reactive shutdowns rather than proactive intervention
Why Pressure & Temperature Monitoring Matters
Cooling performance is directly reflected by pressure and temperature behaviour.
Continuous monitoring enables operators to:
- Detect pressure drop indicating fouling or blockage
- Identify abnormal temperature rise across coolers
- Detect leaks or pump degradation early
- Maintain stable cooling margins
Early detection prevents secondary damage to compressors, motors, and turbines—often far more costly than the cooling system itself. Remote monitoring also reduces the need for personnel access to wet, slippery, and hazardous areas offshore.

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.
