An electrode lead-out device for a capacitive liquid level sensor used in a high-pressure storage tank

Abstract

The invention discloses an electrode lead-out device for a capacitive liquid level sensor of a high-pressure storage tank. communicated to allow the first electrode to enter the first lead-out tube from this end and pass through the other end, and the first lead-out tube is electrically connected to the tank electrically connected to the second electrode of the probe, and the first lead-out tube is electrically connected to the second electrode of the probe. An insulating sealing body is provided between the inner wall of the first drawing pipe and the first electrode, and the insulating sealing body is poured between the inner wall of the first drawing pipe and the first electrode and is connected with the first drawing pipe. The inner wall and the first electrode are integrated into one body. The technical problem solved by the present invention is to overcome the shortcoming that the electrode lead-out device of the existing high-pressure storage tank is prone to seal failure under the action of high pressure, and to provide a capacitive liquid level for high-pressure storage tanks with higher sealing performance and more reliable sealing. The electrode lead-out device of the sensor.

Description

Technical field [0001] The invention relates to the field of liquid level measurement. Specifically, it is an electrode lead-out device for a capacitive liquid level sensor of a high-pressure storage tank. Background technique [0002] Liquid sensor is an indispensable instrument to realize liquid level control, and the application of capacitive liquid level sensor is very common. At present, there are two types of capacitive liquid sensors: integral type and split type. The integral capacitive sensor is immersed in liquid. In order to protect the internal circuit components, the requirements for sealing performance are very high. The split type capacitive liquid level sensor is divided into a probe set in the storage tank and a circuit part set outside the tank. The signal of the probe is transmitted to the circuit part outside the tank through the electrode lead-out end or lead wire passing through the tank body. The electrode lead-out or lead and the tank are sealed by a se...
