Abstract

The invention relates to the field of capacitive sensors, and in particular, relates to a capacitive sensor with a bending design. The sensor comprises a sensor main body, a bending part and a bending assembly; the upper end of the bending part is connected with the tail part of the sensor main body, and the the bending part comprises a vertical section at the upper end and a bending section at the lower end; the bending assembly comprises a mounting piece, a first clamping piece, a second clamping piece and a connecting piece; and the connecting piece is arranged in an oil tank through the mounting piece and is connected with the first clamping piece and the second clamping piece at the same time. Through cooperation of the first clamping ring and the second clamping ring, the specified position of the bending part is clamped and fixed, the bending degree of the bending part is adjusted, the length of the bending part and the length of the sensor main body are made to be matched with oil tanks with different depths, and the detection accuracy is guaranteed. Through transmission of the connecting piece, the upper end and the lower end of the bending part are bent synchronously, the bending amplitude is increased, and secondary damage to the oil tanks is reduced.

Description

technical field [0001] The invention relates to the field of capacitive sensors, in particular to a capacitive sensor with a bending design. Background technique [0002] Liquid level measuring devices are widely used in aircraft, ships, etc., and are mostly used for oil level and water level measurement. There are many measurement principles and methods for liquid level measurement devices, and the mainstream methods include capacitive sensors, pressure sensors, etc. The capacitive sensor is a cylindrical capacitor composed of two coaxial aluminum tubes insulated from each other, and the two metal tubes respectively form the two poles of the cylindrical capacitor. When the input signal is applied to the two poles of the cylindrical capacitor, an electric field is generated, thereby collecting the capacitance value, and the output capacitance value is different when the liquid level in the cylindrical capacitor is different. The characteristic of this sensor is that the ax...
