What Are the Most Common Technologies Used in Angle Sensors?

There are several technologies used in angle sensors, each with its advantages and disadvantages. When choosing an angle sensor, it is important to consider the accuracy, reliability, cost, and environmental conditions of the application.

Inductive Sensors

Sensitivus´ angle sensor uses an inductive technology that has all the features needed in an electrical bike application. This includes absolute angle, high accuracy, and a durable design that can tolerate harsh environments. With the right design, it can be an inexpensive but highly reliable sensor.

Potentiometric Sensors

Potentiometric sensors are the most common type of angle sensors. They work by measuring the change in resistance of a potentiometer as the object rotates. Potentiometric sensors are simple, reliable, and inexpensive. However, they are prone to wear and tear, and temperature changes might affect their accuracy.

Magnetic Sensors

Magnetic sensors use a magnetic field to measure the angle of an object. They work by detecting changes in the magnetic field as the object rotates. Magnetic sensors are highly accurate and can work in harsh environments. However, magnetic interference can cause inaccuracy, which is also a problem in a production environment.

Capacitive Sensors

Capacitive sensors use changes in capacitance to measure the angle of an object. They work by measuring the change in capacitance between two plates as the object rotates. Capacitive sensors are highly accurate and can work in harsh environments. However, they tend to be more expensive than most other technologies and humidity can affect them.

Optical Sensors

Optical sensors use light to measure the angle of an object. They work by shining a beam of light on a reflective surface and measuring the angle of reflection. Optical sensors are highly accurate and can measure angles with high resolution. However, they are more expensive and prone to environmental parameters such as grease and dirt.
