TL;DR: In this article, a novel two-stage autoasymmetrical compensation circuit (AACC) is introduced into the triple-coil debris sensor to automatically suppress the residual voltage in real time to achieve ultrasensitive detection.

TL;DR: This article proposes a self-temperature compensation method based on an analog multiplier, which reduces the circuit thermal drift by more than an order of magnitude and has a unique advantage for high-bandwidth and high-precision sensors and can work efficiently in complex and harsh temperature environments.

TL;DR: In this paper, a special mesh screen was proposed to eliminate the interference to a triple-coil inductive sensor to avoid false alarms and increase productivity, and the results showed that the sensor can detect 353 μm (D) ferrous particles and 706 μm nonferrous particles in a pipe with a diameter of 50 mm.

TL;DR: This article proposes a compensation method for precision sensors considering historical temperature states, which can significantly reduce the thermal drift of the sensors during rapid temperature change process and is expected to function efficiently for any precision sensor in complex and harsh temperature environments.

TL;DR: In this paper, a self-correction circuit of sensor circuit temperature excursion based on an analog multiplier was proposed. But the self-correcting circuit with high precision and high stability is hard to realize since the analog compensation way in the prior art is large in design difficulty, and seriously depends on the precision and stability of the analog operation circuit.
