Sample Inlet/Nozzle: Flow Capacity 0.1-50 L/min

Component Specifications

Definition

A critical component of sampling probes designed to precisely regulate the intake of liquid or gas samples from industrial processes. It ensures representative sampling by maintaining consistent flow rates, preventing contamination, and minimizing turbulence at the entry point. The nozzle geometry is engineered to handle specific fluid properties and process conditions.

Working Principle

Operates by creating a controlled orifice or channel that directs fluid samples into the sampling probe. The design minimizes pressure drop, prevents particle deposition, and maintains laminar flow where required. It often incorporates features like tapered entries, specific diameter ratios, and surface finishes to ensure accurate and repeatable sample collection.

Materials

Stainless steel (316L, 304), Hastelloy, PTFE, PEEK, or ceramic depending on chemical compatibility and temperature requirements. Surface finish typically Ra ≤ 0.8 μm for cleanability.
