    Eddy current displacement sensor is a non-contact inductive type transducer. Measurement range 2mm, probe diameter 8mm, output signal supports 0~5V/10V voltage, 4~20mA current and RS485, corresponding max working current 45/25/40mA. The eddy current displacement sensor is also can be used for vibration measurement, small size, wide applications, good price.

    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.

    Eddy Current Displacement Sensor Probe Structure & Dimension Diagram

    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.

    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: Probe installation gap of eddy current displacement sensor.

    When installing the probe of eddy current displacement sensor, linear measurement range of the sensor and variation of the measured gap should be considered. When the total change of the measured gap is close to the linear working range of the eddy current displacement sensor, pay special attention (when selecting, linear range of the selected eddy current displacement sensor should be greater than 15% of the measured gap).

    Generally, when measuring vibration, installation gap of the probe is set at the linear midpoint of eddy current displacement sensor. When measuring displacement, determine the setting of installation gap according to which direction the displacement changes or which direction the change amount is greater. When the displacement changes in the direction away from the end of the probe, the installation gap should be set at the linear proximal end. Otherwise, it should be located at the linear far end.
