Buy eddy current displacement sensor with ideal price. Measurement range 5mm, probe diameter 16mm, output signal 0～5V/10V voltage, 4～20mA current and RS485 for choose, working current less than 45mA. Inductive eddy current transducer uses non-contact mode, used in linear displacement and vibration measurement.

Applications: By measuring the relative position of the measured metal object and the probe end, eddy current displacement sensor senses and processes it into corresponding electrical signal output. Eddy current displacement transducer adopts non-contact measurement, which can work reliably for a long time, has high sensitivity, strong anti-interference ability, fast response speed, and is not affected by media such as oil and water. Eddy current displacement sensors are widely used in long-term real-time monitoring of shaft displacement, shaft vibration, shaft speed and other specifications of large rotating machinery, and are extended to satellite launch, material identification, weighing measurement, metal plate thickness measurement, material deformation and other application fields.

Note: The shell of the eddy current displacement sensor probe is used to connect and fix the probe head, and is used as a clamping structure when installing the probe. In order to adapt to different applications and mounting occasions, the probe shell has different types and different threads and size specifications.

Eddy Current Displacement Sensor Proximitor Shell Dimension Diagram (Unit: mm)

The proximitor is the signal processing center of the entire eddy current sensor system. On the one hand, the proximitor provides high-frequency AC excitation current for the probe coil to make the probe work. On the other hand, through a special circuit, the proximitor senses the change in the gap between the probe head and the metal conductor. After being processed by the proximitor, a voltage or current output signal that changes with the linear change of the gap is generated.

Tips: Requirements of eddy current displacement sensor for probe holder.

Eddy current displacement sensor is installed on the fixed bracket. Therefore, quality of the bracket directly determines the measurement effect. This requires that the support should have sufficient rigidity to increase the frequency of natural vibration, to avoid or reduce when the measured body vibrates, the support is also excited and self-vibrates. The natural frequency of bracket should be at least 10 times the mechanical rotation speed. Bracket should be parallel to the tangent direction of the tested surface. Eddy current displacement sensor is installed vertically on the bracket. If the center line of probe is at an angle of 15° in the vertical direction, although this has no effect on the system characteristics, it is better to ensure that eddy current displacement sensor is perpendicular to the measured surface.
