Dual-axis Tilt Sensor

Single-axis sensors measure tilt in one plane, which is fine if your structure only moves in a known direction. Dual-axis units give you pitch and roll simultaneously from one mounting position. For retaining walls, bridge piers, or any situation where deformation could twist in unforeseen ways, the biaxial data eliminates blind spots. It also saves you the trouble of aligning two separate sensors perfectly orthogonal, which is trickier than it sounds on a dusty construction site.

Most MEMS-based tilt sensors in this class deliver a total accuracy of around ±0.01° to ±0.05° over a narrow range at room temperature, though real field accuracy depends heavily on temperature compensation. Our designs incorporate onboard calibration and thermal drift correction so you get repeatable readings across the full operating temperature range. If you need higher precision for critical monitoring, we can discuss factory calibration against reference inclinometers.

Yes. Standard enclosures are rated IP67, meaning they withstand temporary immersion and are sealed against dust. For aggressive environments—coastal salt spray, acidic mining runoff—we offer stainless steel housings and marine-grade connectors. The cable glands are also strain-relieved and sealed; we recommend routing cables with a drip loop to prevent water tracking into the connector. Periodic visual inspection of the housing seals is good practice, but the internals are nitrogen-purged during assembly to minimize internal condensation risk.

You can order models with 4–20mA current loops, which are robust against electrical noise and support long cable runs without signal loss. RS485 (Modbus RTU) versions allow multi-drop networking and digital communication for up to a few hundred meters. Some models also provide a 0–5V voltage output. We can supply pre-terminated cables of custom lengths, or you can wire your own through the plug connector on site. The pinout diagrams are marked clearly inside the connector cap.

Absolutely. Customization requests we've handled before include longer cable assemblies with armored jackets, different mounting plate dimensions, extended measuring ranges up to ±90°, and special temperature compensation curves for geothermal applications. Lead times for modifications are usually shorter than you'd expect because we keep core sensing modules in stock. Just get in touch with your mounting constraints and output preference, and we'll work out the rest.
