Temperature

Sensa iO’s temperature sensor delivers precise temperature data for process lines, steam systems, heat exchangers, and storage assets.

Vibration

A high-resolution vibration sensor built for predictive maintenance of pumps, motors, compressors, and rotating equipment.

Acoustic

The Sensa iO acoustic sensor identifies ultrasonic leak signatures, gas escape, steam trap failures, and flare noise anomalies.

FAQ - Common Questions

Are Sensa.io sensors compatible with any gateway or network?

Yes, they connect to any LoRaWAN or MQTT infrastructure (Kerlink, Cisco, Milesight, MultiTech, etc.) for flexible integration with existing SCADA systems.

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.

Can the sensor be installed in hazardous or ATEX zones?

Yes. It is designed for harsh industrial environments and comes with ATEX certification.

Do I need wiring or power supply?

No. It is a fully wireless, battery-powered LoRaWAN device.

How long does installation take?

Most installations take under 10 minutes. The sensor mounts using brackets or clamps without modifying existing valves.

Connectivity & Software

Is real-time alerting supported?

Yes. You can receive instant notifications via dashboard, SMS, email, or system integration.

Can it integrate with our SCADA or existing systems?

Yes. Sensa.io provides APIs and integration options for SCADA, DCS, and cloud dashboards.

What happens if the network temporarily goes down?

The sensor stores data locally and automatically syncs it when connectivity is restored.

What network does the sensor use?

LoRaWAN. It supports both private and public LoRaWAN networks.

Battery & Maintenance

What maintenance does the sensor require?

Minimal. It requires occasional battery checks and ensuring the mount remains secure.

Can I replace the battery on-site?

Yes, the design allows for safe, fast battery replacement without removing the entire device.

How long does the battery last?

Depending on the reporting frequency, the battery lasts multiple years.

Use Case & Industry Fit

Does it work for non-oil & gas industries?

Yes—marine, chemical processing, agriculture, environmental control, and energy sectors.

Can the sensor be used on offshore platforms?

Yes. It withstands offshore vibration, salt spray, humidity, and ATEX Zone areas.

Can it help reduce manual inspection rounds?

Absolutely. Most clients reduce field visits by 30–70%, especially in remote or hazardous sites.

Is this sensor suitable for upstream, midstream, and downstream oil & gas?

Yes. It is designed for all sectors including wellheads, pipeline valves, refineries, terminals, and more.

Performance & Reliability

Is the sensor calibrated before shipping?

Yes. Each unit is tested and pre-calibrated before delivery.

Does vibration or extreme temperature affect performance?

No. It is engineered for harsh conditions and maintains reliable readings even in challenging environments.

How accurate is the position detection?

It provides precise, near-real-time valve position tracking with industrial-grade accuracy.

Data Security & Compliance

Where is the data stored?

Data is stored securely in the Sensa.io cloud or your preferred integrated system.

Does it meet industry compliance requirements?

Yes. It meets ATEX, IP67, and LoRaWAN compliance standards.

Is the data encrypted?

Yes. All transmissions follow LoRaWAN security standards with full end-to-end encryption.

Purchasing & Scaling

Is onsite or remote support available?

Yes. We provide installation support, training, and ongoing engineering assistance.

Do you offer bulk or enterprise pricing?

Yes. Custom pricing is available for large-scale rollouts.

Can we start with a pilot before scaling?

Yes. Most clients begin with a small deployment and expand after validating performance.

More

Do you offer a dashboard to visualize valve data?

Yes. Sensa.io includes a cloud dashboard for live monitoring, alerts, and analytics.

How far can the LoRaWAN signal travel?

Typical industrial ranges vary from hundreds of meters to several kilometers depending on infrastructure and line of sight.

Can the sensor detect anomalies or potential failures?

Yes. Movement irregularities are flagged early, helping prevent equipment damage.

How does a valve position sensor improve process safety?

It provides continuous monitoring, real-time alerts, and reduces the risk of manual oversight—all critical for high-risk environments.
