Product catalog summary
Application
Incremental magnetic measuring heads are designed for high precision across a full range of measurements. Their magnetic operating principle and robust construction make them resistant to soiling, ideal for production facilities. They are used in various technologies for monitoring movements, measuring positions, and detecting growth.

Description
The sensors operate on a magnetic principle, using a magnetic scale and a multi-slot reading head to detect linear movements with high precision. The scale is magnetized with a pole spacing of 0.2 mm, and the reading head generates a signal proportional to movement. The signal is digitized, allowing for resolutions from 1 µm to 0.1 µm. Model 8738 DK is noted for its slim shape and high accuracy, suitable for multi-point measuring equipment.

High-precision Incremental Displacement Sensor Series 8738 ► Monitoring both slow and fast movements between machine parts ► Measurements of position and positional changes in components and structural foundations, of servo regulators, valve and robot controllers ► Measurement of growth, and so on Technical changes reserved. All data sheets at www.burster.com Vibration resistant and dust proof Typical applications include: Incremental magnetic measuring heads offer maximum precision over the full range of measurements. As a result of the magnetic operating principle and the robust mechanical construction, they are insensitive to soiling and are therefore ideally suited to use in production facilities. Thanks to the high quality of their measurements, their high protection and long service life, these sensors are used in many technologies (industry, research, development etc.). Measuring ranges between 0 ... 5 mm and 0 ... 100 mm High protection class up to IP66 Description The incremental displacement sensors are based on a magnetic principle: consisting of a magnetic scale and a multi-slot reading head that responds to changes in magnetic flux, they detect linear movements with high precision and resolution. The scale of ferromagnetic alloy – or magnetic tape – is magnetized by an alternating magnetic field with a pole spacing of 0.2 mm. A special recording head and a laser measurement system guarantee that the graduations are very precise. From the magnetic pattern on the scale, the multi-slot reading head generates a signal proportional to the movement. The analog signal generated by the reading head is electronically divided and digitized. Changes in length can be measured with a resolution of from 1 µm down to 0.1 µm. Thanks to its slim shape with a diameter of 8 mm and its high accuracy over the full range of measurements, model 8738 DK is particularly suitable for use in multi-point measuring equipment.
