A transformer running hot doesn't fail instantly. It fails slowly and silently until it doesn't.

Winding temperature is one of the most critical parameters in power transformer health. Missing a thermal event means unplanned downtime, costly repairs, or total asset loss.

NORVI X + EX-RTD4 changes that with a Smart Alarm Architecture:

- SENSING - 4x RTD sensors monitor winding temperatures at critical points in real time
- ACQUISITION - NORVI X collects, processes, and evaluates against configurable safety thresholds
- ALERT (Pre-Alarm) - local LED / display warning before limits are breached
- TRIP (High Alarm) - relay output triggers system trip on critical temperature
- SCADA / DCS - Modbus RTU/TCP integration for full supervisory visibility

Continuous monitoring. Intelligent alerts. Reliable protection.

Reading PLC data through a NORVI X

A full batch of NORVI X units - pre-wired, configured, and ready to ship. Every enclosure identical. Every controller tested.

For OEM machine builders, this is the advantage of a modular, repeatable platform:

- Standardised hardware across every unit
- Consistent I/O configuration per machine model
- Faster assembly — no custom PCBs, no one-off builds
- OTA firmware updates across the entire fleet post-deployment

Build once. Deploy many. Update remotely.

NORVI X was designed for exactly this.

Choosing connectivity for your IoT deployment shouldn't take a research paper.

WiFi, LTE, LTE-M, NB-IoT — each one trades off range, power, speed, and cost differently. Get it wrong and you're either burning battery life or paying for bandwidth you don't need.

- WiFi → high speed, short range, always-on power draw
- LTE → wide area, fast, but higher cost
- LTE-M → wide area, low power, built for IoT
- NB-IoT → massive range, years of battery life, lowest cost — ideal for mass deployments

Different needs, different strengths. Match the radio to the job, not the other way around.

Your network doesn't end where the WiFi signal does.

The NORVI GSM Industrial Controller connects over cellular - no router, no range limits, no dead zones at the edge of the property.

Remote pump stations. Outdoor equipment. Sites with zero network infrastructure. If there's cellular coverage, there's connectivity.

Digital inputs, RS485, relay outputs, and a built-in display - built for the places WiFi never reaches.

Pump stations, unmanned but never unwatched.

With the NORVI GSM-AE08, critical pump station data can be monitored remotely in real time - helping operators stay informed without being physically on-site.

From level, pressure, and flow sensors to the cloud, the system enables:

- Real-time monitoring
- SMS, Emails & push alerts
- Reliable cellular connectivity
- Faster, data-driven decisions
- Reduced manual inspections

A practical telemetry architecture for smarter and more reliable water and wastewater infrastructure.

The reservoir that reports itself.

No gatehouse. No telemetry cabinet. No mains power. Just a white pole, a sealed node, and a sensor cable disappearing into the water.

Every 15 minutes, the EC-M12 wakes up, reads the water level, pushes it over NB-IoT, and goes back to sleep.

Overflow threshold crossed? Alert fires. Level dropping faster than expected? It's already in the trend data.

One node. One sensor. Every reading logged and alarmed - for the cost of a single site visit.

After that, you don't need to come back.

Proprietary PLCs don't just cost more upfront. They cost you forever.

Vendor-locked hardware. Proprietary software. Custom gateways just to get data out. And a replacement cycle that starts the whole thing over.

NORVI X delivers the same industrial control - open stack, modular I/O, native IIoT - at a fraction of the cost and none of the lock-in.

Same control. Open stack. Fraction of the lock-in.

The PLC that speaks Arduino.

Most PLCs lock you into proprietary IDEs, ladder logic, and a vendor's ecosystem. This one runs on an ESP32-S3 - open firmware, Arduino or ESP-IDF, your choice.

But look at what's in this panel:

CPU-S3 → EX-R8 → EX-DI8 → EX-AI4 → EX-UART → EX-AI4

8 relays. 8 digital inputs. 8 analog inputs. UART expansion. All snapping onto a standard DIN rail. All talking to the same CPU over the backplane.

That's industrial-grade modular I/O with the programming model developers already know.

No proprietary runtime. No licensing fees. No relearning a toolchain you hate.

The NORVI X: what happens when an ESP32 grows up.

Most boreholes are invisible.

Dug, capped, and forgotten - until the water runs out or the pump burns dry pulling air.

The problem isn't the borehole. It's that no one knows what's happening 40 metres below ground until something goes wrong.

That's a solvable problem. Five components:

Pressure sensor → EC-M12 → NB-IoT → Cloud → Alert.

Water level drops below safe pumping depth? You know before the pump does. Recharge rate slowing after heavy extraction? It's in the trend data. Seasonal variation across multiple sites? One dashboard.

No power cable. No site visit. No guessing.

Just a 4–20 mA sensor at the bottom of a borehole, a battery-powered node on a pole, and NB-IoT doing what it was designed for - moving small packets of critical data from places no other network reaches.

Groundwater doesn't have to be a blind spot.

Borehole water level: 20%
Alerts: 0

That's the dashboard just moments after commissioning a NORVI EC-M12 at a remote borehole monitoring site.

Sealed. Mounted. Connected. Already transmitting live data over NB-IoT.

No network cable.
No power outlet.
Just a submersible pressure sensor, a SIM card, and a compact battery-powered IoT data logger quietly doing its job from a pole.

From that moment on, the site monitors itself.

Every 15 minutes, water level data is sent to ThingsBoard. If the level drops below the configured threshold, an alert is triggered automatically, no manual inspections required.

That's what reliable, battery-powered cellular IoT looks like.
