BWSENSING High-Precision Modbus Dual Axis Inclinometer (BWS2700)

The BWSENSING High-Precision Modbus Dual Axis Inclinometer (BWS2700) is a dual-axis, high-precision tilt sensor developed by Bewis Sensing using MEMS technology with a fully digital output. Designed for applications where fractions of a degree matter, the BWS2700 measures inclination across a ±30° range on two axes with a manufacturer-stated maximum accuracy of 0.001° and a cross-axis error of just 0.001° — figures the manufacturer describes as the most accurate in the industry for this product class. Communication is handled over a Modbus digital interface with a baud rate adjustable from 2400 to 115200, the output frequency is adjustable between 5 and 100 Hz, and the sensor accepts a wide 9–36 VDC supply. An IP67 protection rating seals the unit against dust and temporary water immersion, making it suitable for demanding industrial and outdoor installations, and Bewis Sensing offers OEM customization for volume integrators.

Background

Bewis Sensing and MEMS inclination measurement

Bewis Sensing (BWSENSING) specializes in inclination and attitude measurement products built on MEMS — micro-electro-mechanical systems — technology. MEMS inclinometers determine tilt by sensing the orientation of an internal micro-machined proof mass relative to gravity, then processing that signal digitally to deliver calibrated angle values. Compared with legacy electrolytic or mechanical tilt sensing, the MEMS approach allows compact packaging, solid-state durability, and digital signal conditioning that can compensate for non-linearity. The BWS2700 sits at the precision end of the company's inclinometer range: the manufacturer positions it as a super-high-accuracy model, with its 0.001° maximum accuracy claimed as the industry's best at the time of publication.

Where the BWS2700 fits in the lineup

Within the BWSENSING portfolio, the BWS2700 is the dual-axis, Modbus-output configuration for high-precision static and low-dynamics inclination measurement. Its defining combination is a deliberately bounded ±30° measurement range — trading wide-angle coverage for resolution and linearity within the band where precision leveling and monitoring tasks actually operate — together with a digital Modbus interface that drops directly into industrial PLC and SCADA environments. The adjustable output rate of 5–100 Hz lets integrators balance responsiveness against bus load, while the adjustable 2400–115200 baud rate accommodates everything from long, noise-prone RS-485 runs at low speed to fast local polling. The manufacturer also accepts OEM customization requests, which typically covers items such as interface, range, or housing adaptations agreed at order time.

Technical Specifications

The values above are taken from the manufacturer's product introduction and series documentation. Detailed electrical characteristics, temperature behavior, dimensions, and mounting information are defined in the official BWS2700 technical manual, and all figures should be confirmed against the current manufacturer datasheet during quotation, since specifications may be updated between revisions.

Why does 0.001° accuracy matter?

An accuracy figure of 0.001° corresponds to detecting a rise of roughly one millimeter over a fifty-seven-meter span — the kind of sensitivity required when monitoring structures and machines whose failure modes announce themselves as barely perceptible tilt changes. At this level, an inclinometer stops being a simple leveling aid and becomes a measurement instrument: it can resolve the slow settlement of a foundation, the thermal lean of a tower through a day-night cycle, or the deflection of a precision machine bed under load. It is worth noting that ultimate real-world accuracy in any precision inclinometer installation also depends on mounting quality, temperature environment, and vibration isolation, so system designers should engineer the full measurement chain to exploit what the sensor can deliver.

How does the Modbus digital interface simplify integration?

Modbus remains the lingua franca of industrial automation, and the BWS2700's native Modbus output means the sensor speaks directly to PLCs, RTUs, data loggers, and SCADA gateways without analog signal conditioning or proprietary converters. Digital transmission eliminates the drift, noise pickup, and calibration burden of analog voltage or current outputs over long cable runs, and the adjustable 2400–115200 baud range lets installers tune the link to cable length and network conditions. Multiple devices can share a bus with distinct addresses, which suits monitoring projects that deploy sensor arrays across a structure. The adjustable 5–100 Hz output frequency gives designers control over the data cadence: low rates minimize traffic for long-term structural logging, while the upper range supports more responsive control and leveling loops. Combined with the wide 9–36 VDC supply tolerance and IP67 sealing, the interface design makes the BWS2700 a field-ready component rather than a laboratory-only instrument.

Who is the BWSENSING BWS2700 for?

The BWS2700 is aimed at engineers and integrators who need reference-grade tilt data inside industrial systems: structural-health-monitoring specialists instrumenting bridges, towers, and buildings; heavy-equipment and platform manufacturers implementing precision leveling; automation engineers aligning machine tools, antennas, and solar-tracking mechanisms; and research or geotechnical teams logging slow deformation over months. It suits projects that already run Modbus infrastructure and that operate within a ±30° window where its accuracy is concentrated. OEM customers with recurring volume can additionally take advantage of Bewis Sensing's customization program to adapt the sensor to their product requirements.

What is the BWSENSING BWS2700 used for?

1. Structural health monitoring — tracking minute tilt changes in bridges, towers, dams, and buildings as an early indicator of settlement or deformation.
2. Precision platform leveling — providing closed-loop feedback for leveling systems on industrial platforms, lifts, and specialized vehicles.
3. Machine and equipment alignment — verifying and maintaining the angular alignment of machine beds, rails, and precision manufacturing equipment.
4. Antenna and solar tracker positioning — supplying accurate two-axis inclination data for pointing and tracking mechanisms.
5. Geotechnical and settlement monitoring — logging long-term inclination trends in foundations, retaining structures, and slopes through Modbus data-acquisition networks.
6. Robotics and automation attitude sensing — giving stationary or slow-moving automated systems a high-resolution tilt reference within a ±30° operating envelope.
