BWSENSING High-Precision Modbus Dual Axis Inclinometer (BWS2700)

A tilt of a thousandth of a degree is invisible to the eye, yet it can be the first sign that a platform is settling or an antenna mount is drifting. The BWSENSING High-Precision Modbus Dual Axis Inclinometer (BWS2700) is built to notice that kind of change. It reads two axes at once, over a ±30° range, and reports the result as a digital value your controller can use directly.

Background

Bewis Sensing and its MEMS approach

BWSENSING is the brand of Bewis Sensing, a maker of inclination sensors. The BWS2700 was launched by Bewis Sensing as a dual-axis, high-precision inclinometer using MEMS technology with digital output. MEMS stands for micro-electro-mechanical systems. In a tilt sensor, a tiny machined structure responds to gravity, and electronics turn that response into an angle.

For buyers in the Caribbean, the practical value of this approach is easy to see. A MEMS device is compact and has no fluid to leak. It can be mounted on equipment where a bulky instrument would never fit. Other BWSENSING tilt sensors sit alongside it in our BWSensing range, and you can compare it with other instruments in the Sensors category.

Where the BWS2700 sits in the range

The BWS2700 is the high-precision member of the family. Its maximum accuracy of 0.001° and its resolution of 0.0005° when completely still are aimed at work where small angles carry real meaning. It is named in three versions by suffix: BWS2700-30-485, BWS2700-30-232 and BWS2700-30-TTL. Ranges of ±5°, ±15° and ±30° are also named. The figures in this article are for the ±30° range.

Industrial users like a sensor that accepts a wide supply and survives rough handling. The BWS2700 takes 9-36VDC, works from -40 to 85 ℃ and is housed in anodized magnesium aluminum alloy. It is a sensor for installations, not for the laboratory bench.

Technical Specifications

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

The manufacturer has not published the weight, the power consumption in watts, the contents of the box, the Modbus register map or the dynamic accuracy; they are confirmed at quotation.

What makes the BWS2700 suited to demanding sites?

Three things stand out in the specification: stability over temperature, a wide supply range and mechanical toughness. The zero bias is ±0.0007 °/℃ across -40~85℃. That matters because a tilt sensor on an outdoor structure in the Caribbean sun will not stay at one temperature. A sensor whose zero point wanders with heat would hide the small movements you installed it to find.

The supply range of 9-36VDC lets the unit run from the common DC rails found on vehicles, cabinets and field equipment. You do not need a dedicated regulated supply for it. The sensor also withstands impacts of 2000g, and its MTBF is stated as ≥90000 h.

Protection needs one clear note. IP67 applies, and the unit is waterproof to IP67 after gluing. If your site sees heavy rain, salt air or washdown, plan that sealing step into your installation and discuss it when you request a quotation.

How does the BWS2700 connect to a computer or controller?

The BWS2700 has a digital output, and the baud rate is adjustable from 2400 to 115200. The output frequency can be set from 5 to 100Hz. A slow rate suits a structure that moves over days, while a faster rate suits a platform that needs frequent angle updates. Both can be set to match your system rather than the other way round.

For setup and checking, supporting serial port debugging software connects the inclinometer to a computer and displays the angle, so you can confirm that the sensor is reading correctly before it goes into the field. The version suffixes 485, 232 and TTL point to different interface options, so please state which one you need when you ask for a quotation.

Who is the BWS2700 for?

Engineers who monitor structures such as bridges, towers, retaining walls and building frames will find the resolution and accuracy useful. Small, slow angle changes are the signal in that work, and a digital output makes logging simple.

Robotics and automation teams can use it for leveling platforms, checking the attitude of mobile machines and feeding angle data into a controller. Teams working with satellite and antenna equipment may value it for aligning and monitoring mounts, where a small tilt changes pointing.

Integrators building their own monitoring systems will appreciate the adjustable output frequency and baud rate. If your project needs a more economical dual-axis device and does not need the 0.001° maximum accuracy, look at the BWSENSING Cost-Effective Dual-Axis Digital Output With Modbus Inclinometer (BWN427) or the BWSENSING Cost-Effective Dual-Axis Inclinometer (BWM427). Check their datasheets for how they compare. For single-axis work, the BWSENSING Cost-Effective Single-Axis Digital Output With Modbus Inclinometer (BWM417) may be enough.

What is the BWS2700 used for?

1. Structural monitoring. Track slow tilt in bridges, towers and walls where small angle changes matter.
2. Platform leveling. Keep work platforms and mounting frames level on two axes at once.
3. Antenna and satellite mounts. Check the attitude of mounts and supports against drift.
4. Robotics and mobile machines. Feed tilt angles to a controller for balance or safety logic.
5. Industrial equipment. Watch booms, arms and frames that work in wide temperature ranges.
6. Test and commissioning. Use the serial debugging software to read angles on a computer during setup.
