Low-error capacitance liquid level detection device

Abstract

The present invention discloses a low-error capacitance liquid level detection device which comprises: a shell, wherein a detection bottle body is placed in the shell, a connection shell is clamped and connected in the inner wall of the right side of the shell, a bearing shell is clamped and connected outside the right side of the connection shell, and an abutting block is fixedly connected to the inner wall of the right side of the bearing shell and plays a role in pushing and extruding the connecting shell; and bearing blocks which are evenly distributed outside the bearing shell, wherein adjusting bolts are connected to the interiors of the bearing blocks in a penetrating mode, a first capacitor block is connected to the interior of the upper side of the connecting shell, a second capacitor block is connected to the interior of the lower side of the connecting shell, and an adjusting rod is connected to the right side of the upper end of the connecting shell in a penetrating mode. According to the low-error capacitance liquid level detection device, in the using process, the capacitance module can be tightly attached to the bottle body, the detection effect is prevented from being influenced, the stability is high when the capacitance module is attached to the bottle body, the capacitance module is not prone to being interfered by the outside world, and therefore errors are reduced, and the detection accuracy is prevented from being influenced.

Description

technical field [0001] The invention relates to the technical field related to liquid level detection, in particular to a low-error capacitive liquid level detection device. Background technique [0002] The capacitive liquid level detection device uses the change of measuring capacitance to measure the level of the liquid level. It detects by contacting the capacitance module with the bottle to be measured. There are more and more various detection devices and detection methods, but The current capacitive liquid level detection device still has many deficiencies. [0003] Chinese patent authorization announcement number CN105074395A discloses an electrostatic capacitive liquid level detection device capable of judging the liquid quality while judging the liquid level. Equipped with: a plurality of electrode pairs (26a-26i), the plurality of electrode pairs (26a-26i) are staggered in the height direction in the tank body (10) storing the liquid; a measuring device (31), whi...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a low-error capacitive liquid level detection device to solve the problem that the capacitive module is difficult to fit tightly with the bottle during use, which affects the detection effect, and the capacitive module is not in contact with the bottle. The stability of body fit is poor, and it is easy to be disturbed by the outside world, resulting in large errors and affecting the accuracy of detection
