Accelerometer Solutions for Structural and Geotechnical Monitoring
Accelerometer
Vibration, tilt, and seismic events can quietly undermine structural integrity long before visible damage appears. An accelerometer captures these subtle movements, converting motion into actionable data. In geotechnical and structural monitoring, the right accelerometer helps engineers track stability in real time, whether it is a bridge pier, tunnel lining, or slope prone to creep. Kingmach manufactures a range of accelerometers designed for such demanding environments. These sensors are not one-size-fits-all; they can be tailored in measuring range, output type, and enclosure to match specific job site conditions. With a supply chain serving projects across multiple continents, Kingmach supports both off-the-shelf orders and custom configurations. The focus stays on delivering data that field crews can actually use—without unnecessary complexity.
Technical Detail
Configured around process stability, mold life, and long-term uptime.
Choosing an accelerometer for field monitoring often comes down to three things: how well it holds up under site conditions, how easily it integrates into existing loggers, and whether you can get it fast enough to keep the project moving. Kingmach accelerometers are built around these practical concerns. The housing options include stainless steel and ruggedized aluminum, with IP ratings that suit outdoor installations. Electrical interfaces are available in common formats—voltage, 4–20 mA, and digital outputs—so connection to standard data acquisition systems is straightforward. Measuring ranges can be selected from low-g (for subtle tilt) to higher-g (for strong vibration), and frequency response characteristics are tuned for typical civil engineering spectra, not lab-only ideals. Beyond the hardware, Kingmach’s factory setup lets you adjust cable length, connector type, and mounting accessories without long lead-time penalties. Technical support is part of the package: application engineers help match sensor specs to your monitoring plan. For integrators, block diagrams and Modbus register maps are shared upfront. Global distribution points shorten shipping times across Asia, Europe, and the Americas. This combination of stock availability and customization avoids the frequent trade-off where you either compromise on specs or wait weeks for a special build.

FAQ
Common technical questions
Which accelerometer range should I select for structural health monitoring?
For most civil structures, a ±2g or ±4g range covers ambient vibration and moderate events. If you are monitoring heavy construction impacts or seismic zones, consider ±10g or higher. Kingmach can adjust the full-scale range to your project’s specific dynamic range needs.
What are the typical output signal options?
Common outputs are voltage (e.g., 0–5 V or ±5 V), 4–20 mA current loop, and digital interfaces like RS-485 with Modbus protocol. The choice depends on your cable length and data logger compatibility. Kingmach supplies all three, and the factory can confirm the best fit if you share your logger model.
How do you protect the accelerometer in buried or underwater installations?
Sealed stainless steel enclosures with IP67 or IP68 ratings are typical for long-term geotechnical use. Kingmach also offers potted cable exits and optional surge protection. It is best to specify the maximum water head and soil chemistry so the sealing compound and housing material can be matched accordingly.
Can I get a custom mounting bracket for an irregular surface?
Yes. Custom mounting accessories—such as studs with specific thread sizes, magnetic bases, or tilt‑adjustable brackets—are available with short lead times. Just provide a sketch or description of the mounting surface and orientation.
What support is available for integrating the accelerometer into an existing SCADA system?
Kingmach provides detailed Modbus register maps and wiring diagrams. Their support team can walk your integrator through the setup, including scaling factors and configuration steps. They also offer pre-configured test reports to speed up field commissioning.
