R5 Gauge – Wireless tiltmeter for 2-axis tilt monitoring

A standalone wireless tiltmeter, ready to use

The R5 gauge is a wireless tiltmeter — also known as a surface inclinometer — designed to remotely monitor the tilt of civil engineering structures, retaining walls, balconies or any other sensitive structure. Fully autonomous, it does not require any additional equipment to operate. Delivered ready to use, it includes everything needed for reliable, accurate and long-term monitoring.

A complete solution delivered with:

• Three embedded sensors: 2-axis tilt, temperature and humidity
• An app with unlimited access duration, on smartphone or PC, to configure and view data
• One year of subscription included, activated only at first start-up. Even after expiry, data remain available in the app
• “Monitoring+” mode to temporarily increase measurement frequency (up to one measurement every 2 minutes and data uploads every hour). This mode is time-limited to preserve the battery and the amount of data
• Supplied fixings (bracket and anchors), for simple installation in all configurations

The R5 gauge wakes up at regular intervals to measure tilt, temperature and humidity, stores the data locally, then transmits it to the app according to the configured upload frequency.

With its intuitive interface, no technical skills are required. The user simply sets three parameters in the app: measurement frequency, data transmission frequency and monitoring start time.

A reusable tiltmeter that can be configured remotely: settings can be adjusted at any time remotely to match site requirements. Once a monitoring campaign is completed, the gauge can be removed, stored and reused for a new job with a configuration identical to the initial installation.

Extended network coverage in Europe and internationally

The R5 gauge connects to LTE-M / NB-IoT networks. These networks use 4G base stations and are specifically designed for IoT devices, with a protocol enabling a longer range and better penetration through walls (it can connect in basements where a phone may have no signal).

Multi-operator connectivity provides coverage in all European countries and in the main countries worldwide. For any questions regarding coverage in your country, please do not hesitate to contact us.

The subscription only starts when the gauge is activated. As long as it has not been commissioned, the subscription does not take effect.

More than 8 years of battery life depending on use

The gauge operates with a 3.6 V lithium battery (included). Battery life depends on the selected settings and operating conditions and can range from more than 2 years to more than 8 years in standard situations. The app provides an estimated remaining battery life during the initial setup.

When the battery approaches end of life, an alert is automatically sent so you can plan battery replacement in advance.

“Monitoring+” mode: enhanced monitoring that can be enabled remotely

To address temporary needs for more intensive monitoring (unusual events, construction works, structural alerts), a “Monitoring+” mode can be enabled remotely via the app.

This mode increases measurement and transmission frequency with the following settings:

• measurement frequency: every 2, 5, 10, 20 or 30 minutes
• data transmission frequency: every 1, 2, 3 or 4 hours

This mode is temporary, as it consumes more energy and data.
The maximum operating duration is automatically determined based on the selected frequency. Once this duration is reached, if the user has not disabled “Monitoring+” mode, the device automatically returns to standard mode to preserve battery life and data usage. This mode can be enabled several times for a series of measurements, up to a limit of 12,000 measurements.

Quick and easy installation of the R5 tiltmeter

The R5 gauge is designed for fast installation that is accessible to everyone, with no specific technical skills required. It can be installed in a few steps using the supplied fixings and the Saugnac app, available on smartphone and PC. A detailed user guide is included to walk you through the process step by step.

Installation steps:

1. Add the gauge in the Saugnac app: scan the QR code on the gauge or manually enter the identifier located under the QR code to add it to your interface.
2. Configure operating settings: in the app, set:
   • the time of the first measurement
   • the measurement frequency: every 1h, 2h, 4h, 6h, 8h, 12h or 24h
   • the data transmission frequency: every 12h, or every 1, 2, 3 or 7 days. Note: the more spaced out the transmissions, the longer the battery life.
3. Power on the gauge: open the housing, switch it on, then close the housing. The gauge initializes automatically, connects to the network and indicates its status via an LED. Once ready, it goes into standby until the time of the first measurement.
4. Mount the gauge on the structure to be monitored:
   
   • solid substrate: use the brass anchors
   • hollow substrate: use the EPDM anchors

Mounting the wireless tiltmeter

The R5 gauge is supplied with two types of anchors:

Brass anchors for solid substrates requiring Ø8 mm holes.
Tools required (not supplied) for mounting on solid substrates with brass anchors: drill, Ø8 mm drill bit, 5 mm hex key + 3 mm hex key to open the housing and power on the gauge.

EPDM anchors for hollow substrates (also suitable for solid substrates) requiring Ø13 mm holes.
Tools required (not supplied) for mounting on hollow (or solid) substrates with EPDM anchors: drill, Ø13 mm drill bit, 5 mm hex key + 3 mm hex key to open the housing and power on the gauge.

To mount the gauge, drill the holes, insert the anchors, prepare the fixings and the bracket to be fixed to the substrate, then place the gauge in the bracket and fine-tune the positioning.

Bonded mounting is also possible on metal substrates, by gluing the bracket with a fast-curing two-component epoxy adhesive.

Subscription and network coverage: reliable, wide-area connectivity

Each R5 gauge is supplied with a one-year multi-operator subscription, valid throughout Europe and in the main countries worldwide. For any questions regarding coverage in your country, please do not hesitate to contact us.
When powered on, the device automatically selects the best available network, using the LTE-M and NB-IoT protocols, specifically designed for IoT communications via mobile operators’ 4G base stations.

Handling network interruptions
In the event of a temporary connection loss, the gauge stores the data locally. It is automatically transmitted the next time a connection is available.
If the interruption persists, the device attempts automatic reconnection, including switching operator if necessary.

Subscription management

• Duration: 1 year from first activation
• Renewal: directly from the app, either by credit card or via a purchase order generated from a quotation
• Price: €49 excl. VAT for one additional year
• Data: after expiry, previously recorded data remain accessible, but no new measurements are transmitted until the subscription is renewed

Protective cover for the R5 gauge – mechanical protection

To protect the R5 gauge during on-site measurements, a dedicated protective cover is available. Made of PVC, it provides an effective barrier against splashes and accidental damage that may occur in outdoor environments or on construction sites.

Designed to fit perfectly over the R5 gauge, it offers a simple and reliable solution to secure the instrument during long-term installation on a structure.

The protective cover for the R5 gauge is available in three colours (other colours available on request).

Real-time tilt monitoring from the Saugnac app

All data measured by the built-in sensors (2-axis tilt, temperature and humidity) is available remotely via the app https://saugnac.app, available free of charge on smartphone and PC. Access to the app remains active even after the subscription ends, and previously recorded data remain available with no time limit.

📊 Data visualization and analysis

• Customizable charts: view trends in clear, exportable charts (image format), ideal for your reports
• Data export: download raw measurements in Excel or CSV format for in-depth analysis
• Dynamic report sharing: generate a secure link providing access to an interactive report containing the most recent data at the time of viewing

🚨 Alert system

The app lets you configure email alerts if a threshold is exceeded, upwards or downwards, relative to the first recorded measurement. This keeps you informed in case of unusual or critical changes. The alert is sent when the data is transmitted.

Integration with your IT system

We provide a standard API to send data to any information system. We can also deliver flat files (CSV) to a secure FTP server. If you want to feed data directly into your IT system without using our app, contact us to set it up.
