Abstract

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 analyzer in 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 set of electrically isolated surfaces. The fitting secures the probe within a transfer arm and establishes the connection between the PCA and the probe.
