Description

technical field [0001] The invention discloses a special detection device and a detection method for the quality of a Hall sensor, belonging to the technical field of sensor detection. Background technique [0002] Hall sensors can detect physical quantities such as torque, pressure, stress, position, displacement, speed, acceleration, angle, angular velocity, revolutions, etc., and have high requirements for zero point error and linearity in various situations when working in harsh environments . In order to detect the quality of the Hall sensor, it is necessary to detect the zero point error in different temperatures for a long time, the linearity of the positive and negative strokes, and the linearity under the conditions of positive bias and negative bias voltage. [0003] In the prior art, for Hall sensor detection, it is necessary to manually adjust the input voltage and detection circuit manually, and then compare the detection result with the standard value, and per...

Problems solved by technology

However, the above-mentioned detection device can only detect two Hall sensors at the same time, and cannot satisfy multiple sensor detection. Further, the detection device can only detect whether the Hall sensor is faulty, but other characteristic parameters of the Hall sensor are all No detection and statistics were done

[0004] The paper titled "Introduction and Detection Method of Integrated Hall Sensor" published in "Electronic News" in 2003 also recorded the simple method to determine whether the Hall sensor is damaged, but still did not make any description of the characteristic parameters of the batch detection Hall sensor and introduction

[0005] If the detection scheme of the prior art is applied to the method of the present invention, the detection time is long, and the manual adjustment parameters are complicated, so it is easy to cause high product detection costs, low production efficiency, and reduce product market competitiveness.
