Vertical In-Place Inclinometer System

The Kingmach vertical in-place inclinometer is built around a durable array of MEMS tilt sensors connected in series. Each sensor node measures angular deviation from vertical in one or two axes. A typical system can monitor boreholes up to 200 meters deep, though we adjust sensor quantity and spacing based on the expected slip zone. Suspension cables and centralizers keep the string centered in the casing, and the bottom wheel or anchor secures the reference point. The digital output—often RS485 or SDI-12—links directly to our proprietary data loggers, which can trigger alarms when tilt rates cross user-set thresholds. Compared to traditional traversing probe methods, this in-place approach eliminates manual field visits and provides a near-continuous deformation profile. For projects needing real-time integration, the logger pushes data via cellular modem to a web dashboard. Common applications include monitoring excavation-induced ground movement near sensitive structures, verifying dam performance during reservoir filling, and tracking slow-moving landslides over multiple seasons. Since everything from sensor calibration to enclosure sealing is done at our facility, we can offer extended warranties and calibration services that third-party integrators often can’t.
