Embodiments are directed to a simple, tool-less, and automated connection between a transfer probe and a capacitive liquid level detection printed circuit assembly (PCA) for use in a clinical analyzerin an in vitro diagnostics (IVD) environment in a hospital or laboratory setting. Advantageously, a single user connection is required: a fitting that is used to attach fluid tubing of the transfer arm to a probe, resulting in a mechanical, fluid, and electrical connection between the probe and the transfer arm. A PCA comprises a plurality of spring-loaded pins and capacitive liquid level detection circuity. A probe comprises a primary tube nested within a secondary tube, wherein the primary tube and the secondary tube comprise respective heads at respective top portions thereof forming a setof electrically isolated surfaces. The fitting secures the probe within a transfer arm and establishes the connection between the PCA and the probe. 实施例涉及在医院或者实验室设置中的体外诊断（IVD）环境中的临床分析器中使用的传送探针与电容性液位检测印刷电路组件（PCA）之间的简单、无工具的自动化连
