BWSENSING Low Cost Dual-Axis Digital Output With Modbus Inclinometer (BWL327S)

Most things that tilt do so slowly, and nobody notices until the tilt has become a problem. A solar array drifts off its sun angle, a tower leans a little further each season, a machine bed never quite sits level. The BWSENSING Low Cost Dual-Axis Digital Output With Modbus Inclinometer (BWL327S) is built to notice those small movements early and report them as plain digital numbers that a controller can act on.

The product is available through this page, by quotation.

Background

The company and its lineage

BWSENSING is a maker of inclinometers and tilt sensors, and its catalog covers single-axis and dual-axis models with several output styles. The BWL327S belongs to a family that also includes the BWL327, the BWL326S and the BWL325S. Within that family, this page describes the BWL327S only, and every figure below belongs to it.

For buyers around the Caribbean, a sensor line like this matters because the work is practical: solar installations, telecom and utility structures, and industrial plants all need angle feedback that is simple to wire and simple to read. You can browse the wider range in our Sensors category or see everything from the maker under BWSensing.

Positioning and key technology

The BWL327S measures tilt on two axes at once, across a range of ±90°, and reports it with a resolution of 0.01°. The highest accuracy is 0.1°. The output is digital, with RS232, RS485 or TTL as options, so the angle reaches your controller as data rather than as an analog voltage that has to be conditioned and calibrated.

The housing measures L55mm×W37mm×H24mm, and the size is customizable. The protection level is IP67, which is the reason this model suits outdoor and exposed installations as well as cabinets. The supply input runs from 9 to 35V, a wide window that fits the mixed power rails found in field equipment.

What makes the BWL327S a good fit for exposed sites?

Three things stand out together. The first is the IP67 protection level, which speaks to the dust and water exposure that a sensor on a roof, a mast or a tracker frame will meet sooner or later. The second is the 9~35V input, which lets the sensor share a supply with other field equipment instead of needing a dedicated regulated rail. The third is the MTBF of at least 90000 h, a reliability figure that matters when the sensor sits somewhere that is expensive to reach.

Start-up is quick, under 50ms, so a system that powers up after an interruption has an angle reading almost immediately. The impact resistance is 2000g for 0.5ms, three times per axis, and the insulation resistance is at least 100 MΩ. Together these describe a sensor intended for real installations rather than a bench.

Why does the output frequency and interface choice matter?

Tilt is usually slow, but control loops still need data at a rate that suits them. The BWL327S output frequency is adjustable from 5 to 100Hz, so a leveling routine that wants quick updates and a monitoring station that only needs a steady trickle can both be served by the same sensor.

The interface is a matter of what your system already speaks. RS232, RS485 and TTL are all options, and the product name points to Modbus output. If your site is built around multi-drop serial networks, an RS485 variant is the natural conversation to have. If you are connecting directly to a microcontroller board, TTL may be the simpler path.

If you are comparing against other dual-axis digital models, the BWN427 and the BWM427 are worth a look, and we can set the options side by side with you.

Who is the BWL327S for?

Solar installers and tracker builders are the first group. A tracker needs to know its angle on two axes, continuously, and photovoltaic automatic tracking is one of the applications of the BWL327S. Integrators who maintain towers, masts and tall structures form the second group, since tower tilt monitoring is another.

Industrial plant engineers who need automatic leveling on platforms and machines make up a third group. The fourth is equipment makers in the medical field, where medical instruments are an application and where a compact housing helps.

If your project calls for a different axis count, another model may suit you better. For a single-axis Modbus option, see the BWM417.

What is the BWL327S used for?

1. Photovoltaic automatic tracking. It gives a tracker controller the two-axis angle it needs to follow the sun.
2. Tower tilt monitoring. It reports lean on towers and similar structures so that drift is seen early.
3. Industrial automatic leveling. It feeds angle data to a leveling routine on platforms and machinery.
4. Medical instruments. A compact, digital tilt reading suits instruments that must know their orientation.
5. Equipment orientation feedback. It tells a control system how a machine or mounting frame is positioned.
6. Remote condition monitoring. A digital serial output lets angle data travel to a monitoring station for review.
