Acoustic
Real-Time, ATEX-Certified Acoustic Monitoring for Leak Detection and Process Safety

Product Description
SENSA.iO wireless acoustic sensors deliver continuous monitoring of ultrasonic and audible sound patterns across pipelines, vessels, valves, flares, and critical process equipment. Designed for hazardous and hard-to-access environments, the sensor detects abnormal acoustic signatures such as gas leaks, steam leaks, cavitation, venting, and structural noise — all without wiring or external power. The device is ATEX Zone 1 certified, ensuring safe operation in explosive atmospheres including oil & gas facilities, chemical plants, offshore platforms, mining sites, and hydrogen infrastructure. With a rugged, corrosion-resistant enclosure and modular battery system, the sensor allows fast, tool-free battery replacement while remaining installed in the field. Using LoRaWAN® long-range wireless communication and optional edge intelligence, acoustic data is transmitted securely over distances up to 10 km, accessible via cloud dashboards, SCADA systems, or mobile devices.

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.
General & Functionality
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.
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.
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.
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.
Hardware & Installation
Does it work outdoors or in offshore environments?
Yes. The sensor is IP67-rated, corrosion-resistant, and built to handle rain, saltwater, shock, and vibration.
