Siirtymäanturit

Siirtymäanturit, also known as displacement sensors, are devices used to measure the position or displacement of an object. They are crucial components in a wide range of industrial automation, robotics, and measurement applications. These sensors operate by detecting changes in physical properties that correlate directly with the movement of a target.

There are various types of siirtymäanturit, each utilizing different physical principles. Inductive sensors, for example, detect changes in inductance caused by a metallic target approaching or receding. Optical sensors employ light beams, often using triangulation or time-of-flight principles, to determine distance and thus displacement. Linear variable differential transformers (LVDTs) are another common type, relying on electromagnetic induction to produce an analog output proportional to the position of a movable core. Capacitive sensors measure displacement by detecting changes in capacitance between a fixed plate and a movable target.

The output of a siirtymäanturi can be analog (e.g., voltage or current) or digital, depending on the sensor type and application requirements. They are valued for their accuracy, reliability, and non-contact measurement capabilities in many scenarios, which prevents wear and tear on both the sensor and the object being measured. Their applications span from quality control and assembly line monitoring to advanced scientific research and medical devices.
