BWSENSING Dual Axis Wireless NB-Iot Inclinometer (NB-WS2000)

A hillside that is moving a fraction of a degree a month gives no warning to anyone standing on it, and the places where such movement matters most are seldom the places where a mains supply or a data cable can be run. The BWSENSING Dual Axis Wireless NB-Iot Inclinometer (NB-WS2000) closes that gap. It takes a high-resolution tilt measurement on two axes, recharges from the sun and sends its readings over the cellular network to a cloud platform, so the engineer responsible for a slope, a wall or a foundation can follow it from a desk rather than from a site visit.

Robots Europa, based in Dublin, sells the NB-WS2000 and supplies it to customers throughout the European Union and the DACH region. Robots Europa prepares the quotation, arranges delivery to the project or the office and remains the point of contact for technical questions once the sensors are installed, so a monitoring programme has a single European partner from the first enquiry onwards.

Background

Bewis Sensing Technology and the BWSENSING range

BWSENSING is the brand of Bewis Sensing Technology LLC, an innovative and fast-growing company established in 2010. Its catalogue spans inclination sensors for industrial machinery, automation and structural work, from compact digital modules with serial or fieldbus outputs to complete wireless monitoring nodes. The NB-WS2000 sits at the wireless end of that range: rather than a component to be wired into a host controller, it is a self-contained field instrument intended to report on its own. The wider family is presented on the BWSensing brand page, and further measuring equipment is gathered in the Sensors category.

Precision delivered over a cellular link

Inclinometers use gravity as their reference and express tilt as an angle from the horizontal. What separates a monitoring-grade instrument from a simple level switch is how small a change it can see and how faithfully it reports it. The NB-WS2000 combines a fine angular specification with NB-IoT and 2G-GSM connectivity, which means the measurement does not depend on a local gateway or a data logger cabled to the sensor. NB-IoT is a low-power cellular technology designed for devices that send small amounts of data at intervals, while 2G-GSM offers an established network layer in areas where coverage varies. Solar charging removes the routine of battery replacement visits, which on remote or difficult terrain is often the largest hidden cost of a monitoring scheme.

Technical Specifications

Specifications are as published by the manufacturer and are confirmed against the datasheet at quotation. The manufacturer has not published the dimensions, weight, housing material, supply voltage, power consumption, battery capacity, reporting interval, zero temperature drift, certifications, software or app details, or what is included in the box; Robots Europa confirms these at quotation.

What makes a wireless NB-IoT inclinometer different from a wired one?

A conventional digital inclinometer is a measuring element: it produces an output, and something else has to power it, read it, store the values and pass them on. On a factory machine that is straightforward, because the controller is already there. On an embankment, a cutting or a bridge pier, every one of those functions becomes a piece of site infrastructure, with trenching, cabinets, loggers and the maintenance that comes with them.

The NB-WS2000 folds those functions into one unit. Its connectivity is cellular, over NB-IoT and 2G-GSM, so readings leave the site without a local network. Its energy comes from solar charging, so there is no supply to run. And its data lands in the Customizable Monitoring Cloud System, where the project team can view and organise the measurements. The measuring performance is not sacrificed for that convenience: the instrument offers 0.001° accuracy and 0.0007° resolution in a dual-axis design, which is the level of detail needed to separate genuine slow movement from noise.

The trade-off is one of integration style. Where a project already has a control system, a PLC or a SCADA network on site and simply needs another input, a wired module is usually the more natural choice. Where the asset is isolated, spread over a large area or only temporarily instrumented, a wireless node such as the NB-WS2000 avoids building infrastructure that would otherwise outweigh the sensors themselves.

How does the NB-WS2000 fit into a monitoring programme?

In practice, a monitoring programme begins with a baseline: sensors are fixed to the structure or ground, their initial angles recorded, and every later reading is compared with that starting point. A dual-axis instrument tracks rotation in two perpendicular directions, so the team can see not only that an element is moving but in which direction it leans. Because the NB-WS2000 reports through the cellular network, a group of sensors across one site, or several sites, can feed the same cloud view, and the customisable platform allows the presentation to be shaped around the project rather than the other way round.

Before an order is placed, it is worth checking cellular coverage at each installation point, agreeing how often readings are needed and deciding how alarms should be handled. Robots Europa works through these points with the customer while preparing the offer.

Who is the NB-WS2000 for?

The NB-WS2000 is aimed at organisations that are responsible for assets which move slowly and sit far from convenient power and data. Geotechnical consultants and monitoring contractors are an obvious group, particularly on slopes, embankments and excavations where a cabled system would be costly or short-lived. Infrastructure owners and operators of roads, railways and waterways fall into the same category, as do engineers overseeing settlement near construction works, and those responsible for older buildings or heritage structures where intrusive cabling is unwelcome. Research groups running long field campaigns may also value the independence from local infrastructure.

The same wireless family also includes the NB-WM410, NB-WK100 and NB-WL300, and Robots Europa can compare them with the NB-WS2000 on request. For buyers whose sensors will be wired into an existing controller, the cabled BWSENSING modules are often the better fit: the BWSENSING Cost-Effective Dual-Axis Digital Output With Modbus Inclinometer (BWN427) for Modbus networks, the BWSENSING Cost-Effective Dual-Axis Digital Output Inclinometer (BWM426) for a digital output, and the BWSENSING Cost-Effective Single-Axis CAN Output Inclinometer (BWM415) where a single axis on a CAN bus is sufficient.

What is the NB-WS2000 used for?

1. Slope and landslide monitoring — tracking slow ground rotation on hillsides and cuttings that lie beyond mains power.
2. Retaining walls — following the lean of walls behind roads, rail lines and excavations over months and years.
3. Foundations and settlement — watching buildings next to construction works for tilt caused by nearby excavation.
4. Bridges and piers — observing the rotation of piers, abutments and decks as part of structural health monitoring.
5. Embankments and dams — keeping watch over earth structures that span long distances and are costly to cable.
6. Heritage structures — monitoring towers, façades and historic walls where discreet, cable-free installation is preferred.

Which networks does the NB-WS2000 use to send data?

It communicates over NB-IoT and 2G-GSM. Coverage at each installation point should be checked before deployment.

How is the NB-WS2000 powered?

The instrument uses solar charging. Robots Europa can advise on the energy budget for your sites.

Where are the measurements viewed?

Is the NB-WS2000 CE marked?

The manufacturer has not published certification details for this model. Robots Europa sets out the applicable marking in the offer.

How does it differ from the wired BWSENSING inclinometers?

Summary

The movements that threaten slopes, walls and foundations are small, slow and usually located far from power and cabling. The NB-WS2000 answers that combination with a dual-axis measurement of 0.001° accuracy and 0.0007° resolution, cellular reporting over NB-IoT and 2G-GSM, solar charging and a customisable cloud platform, turning a remote asset into one that can be followed from anywhere. Robots Europa supplies, quotes and supports it across the European Union and the DACH region.
