BWSENSING Dual Axis Wireless Lora Inclinometer (LR-WL300)

A structure rarely gives way all at once. A retaining wall leans a little further each winter, a bridge pier settles after a flood, a mast takes on a tilt that no one can see from the ground. The instrument that would have caught it early is often the one nobody wanted to cable across the site. The BWSENSING Dual Axis Wireless Lora Inclinometer (LR-WL300) tackles that problem from the other end: it measures tilt on two axes exactly where the movement happens, sends its readings over a LoRa wireless network, and can be charged by solar energy so that it stays in place for the long haul.

Robots Europa, based in Dublin, supplies the LR-WL300 to customers throughout the European Union and the DACH region. We prepare your quotation, arrange delivery to your site or office, and remain your point of contact for technical questions once the sensors are installed, whether you are equipping a single pilot structure or a monitoring programme that covers a whole portfolio of assets.

Background

Bewis Sensing Technology and the BWSENSING brand

The LR-WL300 is made by Bewis Sensing Technology LLC, a company established in 2010 that describes itself as an innovative and fast-growing business. Since 2019 its products have been sold worldwide under the BWSENSING brand. The wider BWSensing range covers inclination sensing in several forms, from compact wired digital inclinometers for machines and equipment to the wireless units built for monitoring structures in the field.

Within that wireless family, the sources name four versions: LR-WK100, LR-WL300, LR-WM410 and LR-WS2000. This page deals with the LR-WL300 alone, and every figure quoted here belongs to that version. The manufacturer presents the LR-WK100 and the LR-WL300 together as LoRa wireless inclinometers specially designed for structural health monitoring, which tells you the purpose for which this product was conceived.

Wireless tilt sensing for structural health monitoring

Structural health monitoring is about trends rather than single readings. Engineers want to know whether a structure is moving, in which direction and how quickly, and they want that record to run for months or years without gaps. Inclinometers are central to that work because a change in angle is often the first measurable sign of settlement, rotation or deformation.

LoRa is a long-range, low-power radio technology widely used for this kind of telemetry. In a typical deployment the sensors send periodic readings to a gateway, which forwards them to a server or cloud platform where they are stored, charted and checked against alarm thresholds. The LR-WL300 combines that radio link with dual-axis measurement and the manufacturer's Customizable Monitoring Cloud System, so that tilt data can travel from a remote structure to an engineer's screen without a cable run in between.

Technical Specifications

Specifications are as published by the manufacturer and are confirmed against the datasheet at quotation.

The manufacturer has not published the weight, the dimensions, the measuring range, the IP rating, the operating temperature, the battery capacity, the power supply, the contents of the box, the operating frequency band or the output data rate; all of these are confirmed at quotation.

What makes the LR-WL300 different from a wired inclinometer?

A wired inclinometer is an excellent choice when the sensor sits on a machine, inside a cabinet or close to a data logger. On a structure spread over a wide area, the cable becomes the project. It has to be routed, protected, maintained and, sooner or later, repaired after a contractor's excavator or a winter storm has found it. Each additional measuring point adds another run of cable and another connection that can fail.

The LR-WL300 removes that dependency. Its readings travel over a LoRa wireless network with a maximum transmission distance of 5 KM, so a sensor on a distant pier, embankment or tower can report back without a physical connection to the monitoring station. The data then arrive in the Customizable Monitoring Cloud System, where they can be viewed and analysed rather than collected by hand from a logger on site.

Measurement quality is not sacrificed for the wireless link. The LR-WL300 offers an accuracy of 0.1° and a resolution of 0.01°, measured on two axes. Resolution matters particularly in monitoring work, because it determines how finely a slow change can be tracked from one reading to the next.

Where a wired solution suits the job better, for example on equipment that already has a control network, BWSENSING also offers wired models such as the BWSENSING Cost-Effective Dual-Axis Digital Output With Modbus Inclinometer (BWN427) and the BWSENSING Cost-Effective Dual-Axis Inclinometer (BWM427). Robots Europa will gladly help you weigh one approach against the other.

Can the LR-WL300 run unattended for long-term monitoring?

Long-term monitoring is exactly what the LR-WL300 was designed for. The manufacturer states that it can be charged by solar energy, meeting the needs of high-precision long-term monitoring. On a remote structure, every site visit costs time, access arrangements and sometimes traffic management or rope access; a sensor that replenishes its own energy reduces the number of those visits considerably.

For planning purposes, it is worth discussing the power arrangement and the radio set-up with us before you order. LoRa equipment operates in regional frequency bands, and for an installation in the European Union the band must match local rules and your gateway. Robots Europa makes sure that the sensors and the network fit together from the first day.

Who is the LR-WL300 for?

The LR-WL300 is aimed first at structural and geotechnical engineers and the consultancies that run monitoring programmes on their clients' behalf. For them, a wireless dual-axis sensor with cloud software shortens installation and turns a periodic manual survey into a continuous record.

Infrastructure owners and operators form the second group: authorities and companies responsible for bridges, embankments, towers and other assets that need to be watched over years rather than weeks. Contractors working next to existing structures, for example during excavation or tunnelling, can use the sensors to document that neighbouring buildings stay where they should.

Universities and research institutes studying structural behaviour will value the resolution of the measurement and the ability to collect data from field sites without permanent cabling. System integrators building wider monitoring platforms are a further natural audience, since the LoRa link and the cloud system give them a defined path for the data.

The LR-WK100 shares the same structural health monitoring purpose and solar charging; if you are choosing between the two, Robots Europa will gladly set them side by side for you. For applications on machines or in equipment, the wired models in our Sensors category are usually the better starting point.

What is the LR-WL300 used for?

1. Bridge monitoring: tracking the tilt of piers, abutments and decks to detect settlement or rotation over time.
2. Slopes and embankments: watching for gradual movement on cuttings, embankments and hillsides above roads or railways.
3. Retaining walls and excavations: recording whether walls and adjacent structures lean during and after construction work.
4. Towers and masts: following the inclination of telecommunications masts, pylons and similar tall structures.
5. Buildings and heritage structures: documenting long-term movement in older buildings where cabling would be intrusive.
6. Tunnels and underground works: observing linings and nearby structures during and after tunnelling.
