tiltmeter monitoring

A tiltmeter uses an accelerometer or electrolytic sensor to detect changes in angle from vertical. As the structure tilts, the internal sensor produces an electrical signal proportional to the tilt. Data is then logged and converted to displacement or rotation values.

In-place inclinometers are typically installed inside borehole casing to measure subsurface deformation along a vertical profile, while surface tiltmeters are anchored directly on a structure like a wall or beam to monitor angular change at a single point. The choice depends on whether you need deep profile data or spot measurements.

Yes, most Kingmach tiltmeters output standard signals like 4-20 mA, RS485, or SDI-12, which are compatible with a wide range of off-the-shelf data loggers. If a project uses a specific brand, the team can often advise on wiring and configuration.

It depends on the expected movement and the precision required. For subtle early-warning monitoring in tunnels or dams, a high-resolution model with a range of ±15 degrees might be appropriate. For more dynamic sites like active landslides, a wider range of ±30 degrees may be better. Our application engineers can help match the spec to the site conditions.

Most tiltmeters come pre-calibrated from the factory, but field checks using a tilt table or known angle are still good practice. Kingmach offers calibration certificates and can guide technicians through the process remotely or arrange for a service center check if drift is suspected.
