Eddy current sensors, also known as eddy current displacement sensors or inductive sensors, are devices that utilize the principles of electromagnetic induction to detect and measure physical parameters such as displacement, position, velocity, and thickness. These sensors operate by generating an alternating magnetic field that induces eddy currents in a nearby conductive target. The interactions between these eddy currents and the sensor's magnetic field provide the basis for accurate and reliable measurements.
Key Features and Advantages
High Accuracy and Reliability:
Our Eddy Current Sensors are designed for high accuracy, offering precise measurements in industrial environments where traditional contact-based sensors would fail. The sensors can operate effectively in temperatures ranging from -40°C to +150°C and are capable of providing results with an accuracy of up to ±0.5%. The sensors use advanced harmonic control and material performance optimization to ensure stability and reliability over time.
Non-contact Measurement:
Eddy Current Sensors offer a non-invasive way to measure displacement, thickness, and other material properties, making them ideal for delicate or high-speed operations where traditional contact-based sensors might damage the material or affect performance.
Wide Application Range:
These sensors are widely used in industries such as automotive, aerospace, manufacturing, and robotics, particularly in situations that require the detection of small gaps, wear and tear, or surface defects in metals. They are also used for monitoring motor rotor positions, detecting vibrations, and evaluating material thickness without making physical contact.
Structural Design Optimization
Our Eddy Current Sensors are designed with precision and durability in mind. The structural strength is optimized through thorough risk analysis of structural stress, ensuring a solid, long-lasting design. The sensor's construction is carefully modeled and tested using various simulation techniques, such as:
Simulation of the Force-Bearing Strength: Ensuring the entire structure can withstand external forces without failure.
Mold-flow Analysis: This ensures that plastic components are optimized for performance and stability under different manufacturing conditions.
Analysis of the Pull-off Force and Deformation: Analyzing the forces that could affect the interlock mechanism and identifying potential failure points to avoid any operational disruptions.

Analysis of rotor assembly
Analysis of the Pull-off Force of interlock
Analysis of deforming of interlock
