BWSENSING Dual Axis Wireless Lora Inclinometer (LR-WL300)

The hardest part of watching a structure is rarely the sensor. It is the cable that has to reach it. The BWSENSING Dual Axis Wireless Lora Inclinometer (LR-WL300) removes that cable from the plan: it measures tilt on two axes, sends the readings over a LoRa wireless network, and can be charged by solar energy for long-term monitoring.

The product is available through this page, by quotation.

Background

Bewis Sensing Technology and the BWSENSING brand

The LR-WL300 is made by Bewis Sensing Technology LLC, a company established in 2010. From 2019, BWSENSING is the approved global brand, and that is the name you will see on the instruments, the datasheets and this page.

The brand is built around inclination and tilt measurement. Our store carries a wider family of BWSENSING instruments in the BWSensing category, and the broader range of measurement devices sits in the Sensors category. The LR-WL300 is the wireless, long-range member of that family.

Positioning and key technology

The LR-WK100 and LR-WL300 are LoRa wireless inclinometers specially designed for structural health monitoring. The LR-WL300 is the dual-axis version, so it reports tilt along two directions instead of one. That matters on real structures, because movement seldom follows a single line: a wall leans outward and sideways, a mast bends toward the prevailing wind, a slope creeps down and along.

The second key technology is LoRa, a low-power, long-range radio method widely used for sensor networks. Instead of wiring each sensor back to a logger, the LR-WL300 joins a LoRa wireless network. A customizable monitoring cloud system completes the picture, so the readings end up where the people who need them can see them.

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

A wired inclinometer is a fine instrument when the site allows for it. The store lists several, such as the BWSENSING Cost-Effective Dual-Axis Inclinometer (BWM427) and the BWSENSING Cost-Effective Dual-Axis Digital Output With Modbus Inclinometer (BWN427). Those are digital-output instruments, made for installations where a data line is part of the design.

The LR-WL300 answers a different problem. When a measuring point is on a remote embankment, on a tower, or across a stretch of ground where trenching a cable is slow, the wireless link becomes the deciding feature. The maximum transmission distance of 5 KM means the sensor and the receiving end do not have to sit next to each other. The solar charging option adds a second freedom: the sensor does not depend on a power line being run to it.

The measurement itself is not given up for convenience. An accuracy of 0.1° and a resolution of 0.01° describe an instrument meant for slow, small movements, which is exactly what structural monitoring looks for. This suits high-precision long-term monitoring, where a sensor must keep reporting for a long time without constant visits.

How does LoRa help with structural monitoring?

Structural movement is usually slow. A bridge pier does not tilt by the hour; it shifts over weeks and seasons. A monitoring system therefore does not need a fast, bulky data stream. It needs a link that reaches far, costs little energy, and keeps working for years. LoRa was designed with that kind of traffic in mind, and that is why it suits an inclinometer.

With the LR-WL300, the readings travel over the LoRa wireless network and are handled by a customizable monitoring cloud system. Customizable is the useful word. Every project has its own points, its own reporting habits and its own people who need to know. A system that can be shaped to the project fits better than a fixed screen made for someone else's site.

If you are planning a larger network, tell us how many measuring points you expect and how far apart they sit, and we will shape the quotation to your layout.

Who is the LR-WL300 for?

The first group is engineers and consultants responsible for structural health monitoring: bridges, buildings, retaining walls, towers and similar structures where tilt is an early warning. The instrument was designed for this purpose, so it is the natural choice for them.

The second group is contractors and site managers who need monitoring on temporary or hard-to-reach works, such as excavations, embankments and slopes. A wireless sensor goes in faster than a cabled one and does not get in the way of the work.

The third group is utilities and operators of remote assets, for example poles, masts and other tall structures spread over wide areas. The LoRa range and the solar charging option suit them, because visiting each point is the expensive part.

The fourth group is integrators and research teams building their own monitoring solutions. For them, the customizable cloud system is the draw. If your project needs only a single axis, or a wired digital output, the store also lists models such as the BWSENSING Cost-Effective Single-Axis CAN Output Inclinometer (BWM415), and we can help you compare.

What is the LR-WL300 used for?

1. Structural health monitoring. Tracking the slow tilt of bridges, buildings and other structures so that changes are seen early.
2. Slope and embankment watching. Following two-axis movement on ground where cabling is slow or impractical.
3. Tower and mast monitoring. Keeping an eye on the lean of tall structures spread across a wide area.
4. Long-term unattended monitoring. Running for long periods with solar charging, so fewer site visits are needed.
5. Remote sensor networks. Linking several measuring points over a LoRa wireless network with a range of up to 5 KM.
6. Custom cloud reporting. Feeding tilt data into a customizable monitoring cloud system shaped to the project.

Frequently Asked Questions

Is the LR-WL300 a single-axis or a dual-axis sensor?

It is a dual-axis inclinometer. It measures tilt along two axes, with an accuracy of 0.1° and a resolution of 0.01°.

How far can the LR-WL300 transmit?

The maximum transmission distance is 5 KM over its LoRa wireless network.

Can the LR-WL300 run on solar power?

Yes. It can be charged by solar energy, which meets the needs of high-precision long-term monitoring.

What software comes with the LR-WL300?

The product is offered with a Customizable Monitoring Cloud System. Details of how it is set up for your project are given with the quotation.

Can the LR-WL300 follow ground movement on a slope?

It measures tilt along two axes, so movement down and along a slope can be tracked, with the readings sent over the LoRa wireless network.

Is the LR-WL300 the same as the LR-WK100?

No. They share a purpose, structural health monitoring, but the figures on this page belong to the LR-WL300, the dual-axis version.

Where can I buy the LR-WL300 and what does it cost?

You can buy it through this page, by quotation. We do not list a price here; send us your quantity and project details and we reply with a quotation that includes delivery, customs and support arrangements.

Summary

The weak point of many monitoring plans is not the instrument but the cable and the visits it takes to keep it running. The LR-WL300 attacks both: a dual-axis measurement with 0.1° accuracy and 0.01° resolution, a LoRa wireless link with a maximum distance of 5 KM, solar charging for long-term work, and a customizable cloud system for the results. For anyone who needs to see a structure move before it fails, without wiring every point, this page is the starting point.
