Title:
LIQUID LEVEL SENSING APPARATUS AND METHOD, AND METHOD FOR LOWERING SAMPLING PROBE
Document Type and Number:
WIPO Patent Application WO/2024/007403
Kind Code:
A1
Abstract:
The present application relates to a liquid level sensing apparatus and method, and a method for lowering a sampling probe. The liquid level sensing apparatus comprises: a sample rack, having multiple uniform slots capable of accommodating sample containers of various specifications; an image recognition device, used to recognize and distinguish different sample containers, using an image recognition approach, when the sample rack is located in a sample suction region; a sample suction probe assembly, comprising a sampling probe, a laser ranging apparatus, a probe cross beam and a liquid level detection apparatus. One end of the probe cross beam is fixedly provided with the sampling probe, the laser ranging apparatus and the liquid level detection apparatus. The liquid level detection apparatus can detect a liquid level on the basis of a capacitance detection method. A solution of the present invention can greatly increase detection stability and reduce detection dead volume, thereby ensuring that a probe tip does not contact the bottom of a container, causing a probe puncture.
