Magnetoelastic displacement sensor is a device that converts the magnetic function change of the sensitive element caused by external factors such as magnetic field, current, stress and strain, temperature, light and so on into electrical signals, and uses this method to detect the corresponding physical quantities. Magnetoelastic displacement sensor is more and more popular with customers, but because of the particularity of magnetoelastic displacement sensor, we must pay attention to some matters when installing magnetoelastic displacement sensor.

The main purpose of magnetoelastic displacement sensor is to stay away from the electric motor, because the magnetic field intensity generated by the electric motor is far greater than the magnetic field intensity of the earth, so the motor approaching the sensor will produce rigid magnetic distortion. We advocate that the device orientation of the sensor should be as far away from the motor as possible. If the sensor cannot be actually far away from the motor, shielding the motor may be helpful to reduce the distortion, but unfortunately, the method of shielding the motor may be due to the soft magnetic soft magnetic distortion of the shielding material. Use tracking and error size analysis to find a location or shielding method to make the sensor achieve good function in your system.

The skills of magnetoelastic displacement sensor are becoming more and more mature, but at present, the anti-interference performance of magnetoelastic displacement sensor is not very good, so we should try to stay away from places with high magnetic field strength.
