Measuring Angles With Inclinometers

Have you ever found yourself in a situation where you needed to measure an angle, but didn't have the right tool for the job?

Whether you're a DIY enthusiast, engineer, or construction worker, having the right angle measurement tool is essential for accurate and precise work.

That's where inclinometers come in.

These versatile tools are designed to measure angles in a variety of different settings, from construction sites to laboratory experiments.

In this article, I'll explore the world of inclinometers, how they work, and why they're so important for dimensional measurement.

So, whether you're a seasoned pro or just starting out, read on to discover everything you need to know about inclinometers.

Key Takeaways

  • An inclinometer is used for measuring angles of slope, elevation, or depression of an object with respect to gravity's direction.
  • Inclinometers are commonly used in geotechnical monitoring, surveying, and equipment safety.
  • They can measure both inclines and declines using degrees, percentage points, and topos as units of measure.
  • Inclinometers are available in various types and sizes, including manual and digital inclinometers, in-place, vertical, and horizontal installations, and one-axis and multi-axes inclinometers.
  • They have applications in industries such as utilities, oil and gas, power generation, construction, civil engineering, transportation, pipeline inspection, geotechnical instrumentation, entertainment, and agriculture.

How Inclinometers Work

An inclinometer measures the angle of an object's inclination or deformation. It contains orthogonal sensors that measure the angle that the body of the probe makes with vertical or horizontal. Inclinometer probes also have sprung wheels to hold them in the center of the inclinometer casing as the survey is taking place.

The inclinometer casing has four orthogonal grooves along the inside and these are used to guide an inclinometer probe along in order to survey the line of the inclinometer casing.

The sum of the angles in each direction enables the shape of the inclinometer casing to be determined and the difference between the shape of a casing at any particular time and the shape of the same casing at a reference time represents the displacement that occurred between the two times.

Types of Inclinometers

Type Description
Manual Inclinometer/Digital Inclinometer The most commonly used inclinometer systems. Manual inclinometer probes have two MEMS sensors mounted 90° to each other, while digital inclinometer systems use digital sensors.
In-Place Inclinometer Installed vertically to monitor the cut slope or any movement in the shoring wall and embankment.
Vertical Inclinometer Installation Installed vertically to monitor the cut slope or any movement in the shoring wall and embankment.
Horizontal Inclinometer Installation Installed horizontally to monitor the settlement of the soil above the spot of tunnelling.
One-Axis Inclinometers Have a single axis for measurement.
Multi-Axes Inclinometers Can measure inclination angles in multiple directions.

How Inclinometers Help You Measure Angles and Slopes

If you need to measure the angle of a slope or the inclination of an object, you'll need an inclinometer. This handy tool can help you determine the angle of a roof, the slope of a hill, or the tilt of a machine.

Inclinometers work by measuring the angle between the device and the ground, using gravity as a reference point.

There are many different types of inclinometers, including digital and analog versions, and they can be used in a variety of settings, from construction sites to scientific experiments.

With an inclinometer, you can get accurate measurements of angles and slopes, making it an essential tool for anyone who needs to work with dimensional measurements.
