BWSENSING Ultra High Precision Dual-Axis CAN Output Inclinometer (BWS2500)

A bridge deck settles under traffic by an amount no one on the carriageway could ever feel, yet that movement is precisely what an engineer needs to see, logged hour after hour, without a person on site. The BWSENSING Ultra High Precision Dual-Axis CAN Output Inclinometer (BWS2500) is built for that kind of quiet vigilance: it watches the tilt of a structure or platform on two axes and reports it over a CAN bus. Its job is to notice change long before it becomes visible, and to keep doing so through heat, frost, wet weather and shock.

Robots Europa, based in Dublin, sells the BWS2500 and supplies it to customers throughout the EU and the DACH region. Robots Europa prepares each quotation, arranges delivery to your site and provides support from enquiry through to integration, whether you are specifying a single sensor for a test rig or a set of instruments for a monitoring network.

Background

BWSENSING and its inclinometer range

BWSENSING is a manufacturer of tilt-sensing instruments, and its range on this store spans both cost-effective models and the ultra-high-precision class to which the BWS2500 belongs. The broader catalogue includes single-axis and dual-axis inclinometers with different digital interfaces, so the BWS2500 sits within a family rather than standing alone. That matters to integrators: a project can use the precision model where the measurement is critical and a simpler model elsewhere, while keeping to one manufacturer. You can browse the full BWSensing range alongside our wider selection of Sensors. BWSENSING also accepts OEM customisation, which is relevant to equipment builders who need the sensor adapted to their own product.

Dual-axis measurement over CAN

An inclinometer measures its angle relative to gravity. A dual-axis instrument does this on two orthogonal axes at once, so a single unit can track a platform or structure that may lean in any direction, rather than requiring two separate sensors. The BWS2500 delivers its readings over CAN, the robust fieldbus widely used in vehicles, mobile machinery and industrial automation, which allows several devices to share one network and suits installations with long cable runs and electrical noise. The baud rate is adjustable from 25k to 500k and the output frequency from 5 to 100 Hz, so the sensor can be matched to an existing bus rather than forcing the bus to adapt to the sensor. The model is offered in three measuring ranges: ±5°, ±15° and ±30°.

Technical Specifications

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

The manufacturer has not published the package contents, details of the output signal beyond the CAN interface, or the cable length; we confirm these with you at quotation.

What sets the BWS2500 apart from a cost-effective inclinometer?

The difference lies less in what the sensor measures than in how small a change it can be trusted to report, and for how long. With a highest accuracy of 0.001° and a resolution of 0.0005° when completely still, the BWS2500 is aimed at applications where the signal of interest is a very slow, very slight drift: a structure settling, a deck deflecting, a platform creeping out of level. In that kind of work, the sensor's own instability can easily swamp the movement you are trying to detect.

That is why the zero temperature drift figure deserves as much attention as the accuracy. At ±0.0007 °/°C across -40 to 85 ℃, the instrument is specified to keep its zero point steady as an outdoor installation passes from a cold night to a sunlit afternoon. For long-term monitoring, where readings taken months apart are compared, a stable zero is what makes the comparison meaningful.

Robustness completes the picture. IP67 protection, an operating range of -40 to +85 ℃, impact resistance of 2000g for 0.5ms three times per axis, insulation resistance of at least 100 MΩ and an MTBF of at least 90000 h describe a sensor intended to be mounted and left in place. The wide 9-36VDC supply input also simplifies installation on vehicles, machines and field cabinets, where supply voltages vary.

Which measuring range should I choose?

The BWS2500 is offered with ±5°, ±15° and ±30° measuring ranges. As a general principle in inclinometry, the range should cover the largest tilt the application will realistically see, with some margin, but no more than that. Structural monitoring of bridges and buildings usually involves very small angles, so a narrow range is a natural starting point. Platforms that are deliberately tilted and then levelled, or equipment that moves through larger angles, may call for a wider range. Because the published accuracy is stated as the highest figure for the model, we confirm the accuracy that applies to your chosen range against the datasheet when we prepare your quotation.

Who is the BWS2500 for?

The BWS2500 is intended for engineers and organisations for whom a fraction of a degree is significant. Structural health monitoring specialists and civil engineering consultancies will find it suited to bridges, buildings and other assets that are observed over long periods. Machine builders and automation integrators working on precision platforms can use it as the feedback element in automatic levelling systems, with the CAN interface fitting directly into machine networks. Defence and specialist equipment manufacturers looking at automation of military equipment are another segment the manufacturer names. OEMs that need a tailored sensor can take advantage of BWSENSING's acceptance of OEM customisation.

Not every project needs this level of precision. If your application tolerates a coarser measurement, or only requires one axis, a model from the cost-effective range may be the better fit: the BWSENSING Cost-Effective Single-Axis CAN Output Inclinometer (BWM415) keeps the CAN interface for single-axis tasks, while the BWSENSING Cost-Effective Dual-Axis Digital Output With Modbus Inclinometer (BWN427) suits systems built around Modbus. We are happy to compare the options with you before you decide.

What is the BWS2500 used for?

1. Bridge deflection monitoring – tracking how a span tilts and deflects under load and over time.
2. Building health monitoring – recording settlement or lean of structures as part of long-term asset surveillance.
3. Precision platform automatic levelling – supplying the angle feedback that lets a control system bring a platform back to level.
4. Military equipment automation – providing attitude information to automated systems on specialist equipment.
5. Networked monitoring installations – sharing a CAN bus with other devices so that several measurement points report to one controller.
6. OEM integration – building a customised version of the sensor into a manufacturer's own machine or instrument.

Frequently Asked Questions

How many axes does the BWS2500 measure?

It measures inclination on two axes, so one unit can follow tilt in both directions of a platform or structure.

What interface does it use?

The BWS2500 outputs over CAN, with a baud rate adjustable from 25k to 500k and an output frequency adjustable from 5 to 100Hz.

Which measuring ranges are available?

The sensor is offered in ±5°, ±15° and ±30° versions. We confirm the figures for the version you select at quotation.

Can it be installed outdoors?

It carries IP67 protection and is specified for operation from -40 to +85 ℃, which makes it suitable for exposed installations such as bridges and building exteriors.

What power supply does it need?

It accepts a wide 9-36VDC input and draws 20-40 mA with no load. It starts up in less than 3s after power-on.

Is OEM customisation possible?

Yes, BWSENSING accepts OEM customisation. Please describe your requirements in your enquiry so that Robots Europa can clarify them with the manufacturer.

Where can I buy the BWS2500 and what does it cost?

You can buy it from Robots Europa, which supplies customers across the EU and the DACH region. The cost depends on the range, quantity and configuration, so we provide it in a tailored quotation that you can request on this page.

Summary

Some movements are too small to see and too important to miss. The BWS2500 is designed for exactly those: it combines dual-axis measurement, a highest accuracy of 0.001° and a very low zero temperature drift with a CAN interface that fits into industrial and vehicle networks, all in an IP67 housing built to remain in service for years. For bridge and building monitoring, precision levelling and automation projects, it offers the stability that long-term measurement depends on.
