A detection device for capacitive liquid level sensor

Abstract

The invention discloses a detection device for a capacitive liquid level sensor, specifically relates to the technical field of capacitive sensor detection, comprising a protective box and a supporting plate, the lower surface of the inner wall of the protective box is fixedly connected to the lower surface of a first box body , the lower surface of the inner wall of the protective box is fixedly connected with the lower surface of the inner wall of the second box. The present invention simulates the detection conditions in the case of large shaking by setting the first driving assembly, cam assembly, slide bar, toggle plate, second driving assembly, extrusion wheel, knocking rod and protective box, and at the same time the second driving assembly drives The squeeze wheel rotates to squeeze the moving plate, and then the third elastic component drives the knock rod to knock and vibrate the second box, simulating the testing conditions under vibration, and checking whether the testing results are consistent with the actual amount of liquid added. Consistent, the device can be used to simulate detection situations in various environments, and it is convenient to judge the influencing factors of the detection results and the detection accuracy and stability of the sensor itself.

Description

technical field [0001] The invention relates to the technical field of capacitance sensor detection, and more specifically, the invention relates to a detection device for a capacitance liquid level sensor. Background technique [0002] Capacitive sensors use various types of capacitors as sensing elements to convert the measured physical or mechanical quantities into capacitance changes. In fact, they are capacitors with variable parameters. Capacitive sensors are widely used in the measurement of displacement, angle, vibration, speed, pressure, composition analysis, medium characteristics, etc. The most commonly used are parallel plate capacitors or cylindrical capacitors. [0003] According to the working principle of the sensor, the capacitive sensor can be divided into three types: variable pole distance type, variable area type and variable medium type. [0004] According to the structure of the sensor, the capacitive sensor can be divided into three types of structu...
