Angular Correction
Compensation techniques minimize measurement errors that occur when a sensor face is not perfectly parallel to the target surface. Utilizing tilt suppression maintains the accuracy of displacement measurements during industrial assembly processes where mechanical alignment varies. This correction is performed using multi-coil geometries or signal processing algorithms.
Signal Isolation
Misalignment introduces an asymmetrical air gap that distorts the electromagnetic field of the sensor. This distortion shifts the impedance vector in a way that can be mistaken for a change in distance. Isolation techniques separate the angular error component from the true axial displacement.
Circuit Implementation
Multi-channel sensing arrays measure the distance at several points on the target surface to calculate the angle of inclination. These individual measurements are processed using a matrix of equations to determine the average distance while canceling out the tilt component. The correction process operates in real time to handle dynamic alignment changes during high-speed scans.
This algorithm is implemented in the digital signal processor to ensure low latency and high precision.
Sensor Alignment
Mechanical fixturing remains the primary line of defense against excessive angular errors in high-precision applications. Tilt suppression is designed to handle residual misalignments that cannot be prevented by the mechanical assembly. Combining robust mechanical design with electronic suppression ensures long-term system reliability.
