How Angle Sensors Work

Multifunctional Joint Angle Sensor

The multifunctional joint angle sensor measures the obliquity and orientation of a joint using a tube with a radius as the only required parameter. It reconstructs angular parameters based on voltage outputs on each sample position.

Compact 3D Angle Sensor

The compact 3D angle sensor uses an optical method for three-dimensional angle measurement. It calculates the angle based on the position of the light source and the angle of the reflected light.

Three-Dimensional Laser Angle Sensor

The three-dimensional laser angle sensor uses the diffraction theorem and ray optics analysis to measure small angles in three dimensions. It projects a laser beam onto a surface and measures the angle of the reflected light.

Multi-Beam Angle Sensor

The multi-beam angle sensor uses multiple beams of light to measure the 3D profile of a cylindrical surface. It projects the beams onto the surface and measures the angle of the reflected light.

Steering Angle Sensor

The steering angle sensor measures the steering wheel position angle and rate of turn in vehicles. It is placed in the steering column of the vehicle.

Optical Angle Sensor

The optical angle sensor uses an optical frequency comb laser to measure the angle between two surfaces. It measures the absolute distance between the surfaces, lateral chromatic aberration, or second harmonic generation.

Types of Angle Sensors

There are different types of angle sensors used for dimensional measurement:

  • Gear tooth sensors
  • Potentiometers
  • Optical sensors
  • Magnetic sensors
  • Capacitive sensors
  • Eddy-current sensors
  • Hall effect sensors
  • Linear variable differential transformers (LVDTs)
  • Fiber-optic sensors
  • Non-contact angle position sensors

Get Accurate Measurements with the Inclinometer: A Must-Have for Dimensional Analysis

If you're looking for a reliable way to measure angles, an inclinometer is the tool for you. This device is specifically designed to measure the angle of an object with respect to gravity, providing accurate and precise readings.

Inclinometers are commonly used in construction, engineering, and surveying applications to measure the slope of terrain, the angle of a building, or the tilt of a structure.

With the ability to measure both horizontal and vertical angles, an inclinometer is a versatile tool that can provide valuable data for dimensional analysis.

Whether you're working on a large-scale project or a small DIY project, an inclinometer is a must-have for anyone who needs to get accurate measurements.
