Station Building HVAC ΔP & Air Quality Monitoring (Ventilation Safety & Compliance)
Protects staff, ensures ventilation efficiency
Differential Pressure (ΔP)
Temperature
Quick Overview
| Problem | Compressor and pump station buildings require continuous ventilation to control temperature, gas accumulation, and air quality. Insufficient airflow, clogged filters, or fan failure can lead to unsafe conditions, regulatory non-compliance, and equipment overheating. |
| Solution | SENSAiO’s wireless differential pressure (ΔP) and temperature sensors continuously monitor ventilation performance, filter condition, and indoor climate, providing real-time visibility to facility and HSE teams. |
| Value | Improved worker safety • Regulatory compliance • Reduced energy waste • Predictive HVAC maintenance |
| ATEX | Not always required (safe area buildings) • ATEX sensor variants available for classified zones |
The Operational Challenge
Midstream station buildings house critical equipment such as compressors, pumps, electrical panels, and control systems. These facilities depend on reliable HVAC and ventilation systems to maintain safe and operable conditions.
Common operational challenges include:
- Clogged intake or exhaust filters reducing airflow
- Fan or damper malfunction
- Poor pressure balance between rooms
- Excessive heat buildup from rotating equipment
- Accumulation of hazardous gases or fumes
Traditional monitoring practices often rely on:
- Periodic manual inspection of filters and fans
- Reactive alarms based on temperature alone
- Fixed maintenance schedules rather than actual condition
These approaches may fail to detect gradual ventilation degradation, increasing the risk of unsafe working conditions and equipment damage.
Why ΔP & Air Quality Monitoring Matters
Ventilation performance is best assessed by pressure differentials and temperature trends, not by temperature alone.
Continuous ΔP monitoring enables operators to:
- Detect filter clogging through rising pressure drop
- Verify correct airflow direction and room pressurisation
- Identify fan or damper failure early
Temperature monitoring complements ΔP by:
- Identifying overheating equipment or rooms
- Detecting insufficient cooling capacity
- Supporting energy optimisation
Maintaining proper ventilation and pressure balance is essential for worker safety, equipment reliability, and regulatory compliance.

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.
