Tip/Inlet: Temperature Range -40°C to 200°C

Component Specifications

Definition

The Tip/Inlet is a critical precision component located at the entry point of a probe tube, designed to regulate and direct fluid flow into measurement systems. It ensures controlled sample introduction, prevents contamination, and maintains measurement accuracy by providing a consistent entry geometry. This component interfaces between external environments and internal measurement chambers, featuring specific geometries to minimize turbulence and pressure drops while protecting sensitive internal sensors from particulate matter or aggressive media.

Working Principle

The Tip/Inlet operates on fluid dynamics principles, creating a controlled entry point that reduces flow disturbances and maintains laminar flow characteristics. It functions as a hydrodynamic interface that directs fluid samples into the probe tube while preventing backflow and external contamination. The geometry is engineered to create a smooth transition from external environment to measurement chamber, minimizing pressure loss and ensuring representative sampling. Some designs incorporate filtering elements or pressure-equalizing features to handle varying operational conditions.

Materials

Stainless steel 316L (for chemical resistance), PTFE (for high-purity applications), Borosilicate glass (for transparency and chemical inertness), Aluminum 6061-T6 (for lightweight applications), Ceramic (for high-temperature and wear resistance). Material selection depends on application requirements including chemical compatibility, temperature range, pressure rating, and sterilization needs.
