Linear Displacement Measurement Range of Magnetic Grating Displacement Sensors

Magnetic grating displacement sensors are commonly used sensors for measuring linear displacement. They use changes in the magnetic field to measure object displacement and offer high accuracy, high sensitivity, and long service life. The linear displacement measurement range of a magnetic grating displacement sensor refers to the span it can measure accurately.

The working principle of magnetic grating displacement sensors is based on changes in the magnetic field. They consist of a fixed magnetic grating and a moving magnetic grating. When the object moves, the moving grating shifts, altering the magnetic field distribution. The sensor determines the displacement by measuring these magnetic field changes.

The linear measurement range of these sensors is generally determined by their structure and materials. Typically, the measurement range can vary from a few millimeters to tens of meters. The specific range depends on grating size, magnetic field strength, and sensor sensitivity.

Adjusting the grating size and magnetic field strength can change the measurement range. Smaller gratings and stronger magnetic fields yield smaller ranges, while larger gratings and weaker fields support longer ranges. Sensor sensitivity can also be tuned through material and structural choices to expand or reduce the range.

In practice, selecting the appropriate magnetic grating displacement sensor for the required measurement range is crucial to ensure accuracy and reliability. Consider the sensor's performance specifications and technical parameters when making a selection.
