Non Contact Linear scale

A non-contact linear scale, also known as a non-contact linear encoder or non-contact length measurement system, is a type of device used to measure linear displacement or position without physical contact with the object being measured. These scales provide accurate and reliable measurements in various industrial and scientific applications. They are designed to overcome the limitations of contact-based measurement methods, such as wear and mechanical interference. Here's an overview. .

Description

Working

Optical Technology: Optical non-contact linear scales use light to measure displacement. They may employ methods such as interferometry or optical triangulation to determine the position of a reflective target.

Magnetic Technology: Magnetic non-contact linear scales utilize magnetic fields to measure position. They may use Hall effect sensors, magnetoresistive sensors, or magnetostrictive principles to detect changes in magnetic fields caused by the movement of a magnetic target.

Capacitive Technology: Capacitive non-contact linear scales measure changes in capacitance between two conductive surfaces to determine position.



Feature:

High Accuracy: Non-contact linear scales offer high accuracy and resolution in measuring linear displacement.


Non-Contact Operation: These scales operate without physical contact with the object, minimizing wear and eliminating mechanical interference.


Real-Time Monitoring: Non-contact linear scales provide real-time position feedback, enabling precise control and monitoring.




Durability

Designed to withstand various environmental conditions, including temperature variations and mechanical vibrations.
