Principles and Methods of Stress Detection
Basic principle: The magnetoelastic effect of ferromagnetic materials, where the magnetic properties (such as permeability and magnetic resistance) of a ferromagnetic material change under mechanical stress. Therefore, by measuring these magnetic changes, it’s possible to determine the stress within the ferromagnetic material.
F → Δσ → Δμ → ΔRm → ΔVF is the external force; Δσ is the stress change.
Δμ represents the change in magnetic permeability of the ferromagnetic material.
ΔRm represents the change in magnetic reluctance within the magnetic circuit;
ΔV represents the change in the sensor's output voltage.
The magnetic anisotropy sensor consists of two U-shaped excitation coils and a detection coil arranged perpendicularly to each other. The excitation coil (1.3) generates a stable magnetic field, and any change in magnetic reluctance within the magnetic circuit induces variations in magnetic flux. The detection coil (2.4) then senses these changes by generating an induced electromotive force, thereby achieving the desired detection purpose.- When the ferromagnetic material is free of stress, the material exhibits magnetic isotropy, and the detection coil outputs zero induced electromotive force.
- When a ferromagnetic material is subjected to stress, magnetic anisotropy emerges—manifesting as differing permeability in the direction of the applied stress and perpendicular to it. This anisotropy causes the impedance in the two detection coils to vary, ultimately inducing an induced voltage in each coil.

Frequently Asked Questions
Can't charge the device?
The device may have been left unused for too long, causing the battery to lose charge. You can try charging it for an extended period. If there’s still no response, we recommend sending it in for repair. Also, please use the dedicated charger provided for each device when charging.
Can't connect the thickness gauge's flat plate to the instrument?
First, turn on the tablet’s hotspot and check whether the eight-digit number in the hotspot name matches the eight-digit SN code of the device. If they don’t match, make the necessary adjustments. Then, follow the instructions in the manual to connect the tablet. If you’re still unable to proceed, we recommend contacting customer support for assistance.
How can I fix the issue of fluctuating readings during thickness measurement?
It is recommended to connect the flat plate during the thickness measurement process and observe the waveform. If the waveform appears poor, switch to manual mode for inspection. If no consistent waveform is detected, consider potential material issues or probe damage—replace the probe and try again. If no waveform still appears after replacing the probe, the material itself may be of poor quality, making it unable to generate an effective signal.
