dual axis inclinometer

A single axis inclinometer measures tilt in one plane, like forward/backward motion. A dual axis version adds the orthogonal plane, giving you tilt in two directions at once. This is useful when you can’t predict the direction of movement, such as in slope monitoring or when a structure could tilt diagonally. You essentially get two sensors in one housing, which simplifies installation and reduces cost compared to using two separate single-axis units.

Kingmach’s dual axis inclinometers are housed in IP67 or IP68 rated enclosures as standard, meaning they handle rain, dust, and temporary submersion. For permanent underwater use, we can provide additional sealing or stainless steel housings on request. The sensor electronics are potted to resist vibration and shock, and the connectors are chosen for field use—no delicate lab plugs that fail after a few disconnects.

For analog output models (4-20mA or voltage), the sensor is factory configured to a specific range. For example, a ±15° model might output 4mA at -15°, 12mA at 0°, and 20mA at +15°. Digital versions communicate via Modbus RTU, and scaling is done by reading the register values. We supply calibration sheets with each unit, and if you’re connecting to a data logger, our support team can help with the scaling code.

Standard mounting is via four screws on a flat baseplate. For borehole applications, we provide brackets compatible with 70mm and 85mm O.D. inclinometer casing. Wall-mount and pole-mount clamps are also available. If you have a custom bracket requirement, we can machine adaptor plates. Always consider alignment: dual axis sensors need orientation markings so you know which axis corresponds to which direction. We engrave axis indicators on the housing to avoid confusion.

The MEMS sensing element itself is inherently stable, and we burn-in each sensor before shipping to catch early drift. Temperature compensation is done via internal microcontroller correction, so ambient changes don’t shift your zero point. For multi-year projects, we recommend a yearly check using a calibrated tilt table or simple spirit level reference. If a sensor drifts significantly, it usually indicates physical damage or cable issues, not a systematic drift problem.
