Sample Port / Aperture: Temperature Range -20°C to 200°C

Component Specifications

Definition

A specialized port or aperture component designed for sample interface machines, providing a precisely controlled opening for introducing, extracting, or analyzing material samples in industrial processes. It ensures consistent sample size, prevents contamination, and maintains process integrity during sampling operations.

Working Principle

Operates as a controlled access point that regulates sample flow through precise dimensional tolerances. The aperture geometry and surface finish minimize turbulence and material adhesion while maintaining seal integrity when closed. May incorporate automated opening/closing mechanisms synchronized with sampling cycles.

Materials

Stainless steel (AISI 316L/304), aluminum alloys (6061-T6), PTFE coatings, ceramic inserts for abrasive applications. Surface finish: Ra ≤ 0.8 μm for contamination-sensitive applications.
