Magnetic measuring scales: applications and advantages

What are magnetic measuring scales?

Magnetic measuring scales, also known as magnetic linear encoders, are precision devices used to measure linear displacements. They operate on the principle of detecting changes in the magnetic field along a magnetic tape, which contains alternating areas with different magnetic polarities. As the sensor moves along this tape, the signal is converted into numerical data, which can then be processed by the control system, e.g. in CNC machines or industrial robots.

Applications of magnetic scales

Magnetic measuring scales are widely used in various industries. Below we list some of the most important areas in which they are used:

1. CNC machines - in machining, magnetic rulers are responsible for precise positioning of tools, which is crucial for the accuracy of manufactured elements.

2. Robotics - they enable precise control of the movements of industrial robots, which improves the efficiency and quality of production processes.

3. Industrial automation - rulers are used in transport and production systems, where precise position control is required.

4. Printing industry - they are used in modern printing machines, where precise control of the movement of components is required.

5. Medicine - in diagnostic and surgical devices, where very precise movements are necessary, magnetic rulers help ensure the appropriate precision of operation.

Advantages of magnetic scales

Magnetic scales are becoming increasingly popular due to the numerous advantages that make them superior to traditional measurement methods:

1. Resistance to contamination – thanks to the use of magnetic technology, these scales are less sensitive to dust, grease, oils or other contaminants that can interfere with the operation of optical measurement systems.

2. High precision and repeatability – magnetic scales provide measurement with an accuracy of up to several micrometers, making them an ideal solution in applications where high precision is required.

3. Long service life and low maintenance costs – thanks to the durable construction and lack of mechanical elements exposed to rapid wear, these scales are characterized by long service life and low maintenance costs.

4. Wide range of operating temperatures – magnetic scales are capable of working in extreme conditions, including very low and high temperatures, which makes them reliable in various industrial environments.

5. Easy to install – unlike more complicated measuring systems, magnetic scales are easy and quick to install, saving time and money on integration.

Summary

Magnetic measuring scales are advanced, precise devices that play a key role in modern automation and production systems. Their advantages, such as resistance to contamination, high precision, ease of installation and durability, make them increasingly popular for industrial applications. Thanks to their properties, they can be used in difficult conditions, and their reliability contributes to improving the efficiency of production processes
