The Sampling Probe is the critical interface component of an Automated Sampler system responsible for the direct, controlled extraction of representative material samples from liquids, powders, or granular substances within a process line, vessel, or silo. It ensures sample integrity by preventing contamination and maintaining the physical/chemical state of the sample during the collection phase. The probe is typically inserted into the material source (manually or via an automated actuator). It utilizes mechanisms such as vacuum suction, pressure differential, or a mechanical scoop/cutter to draw or capture a defined volume of the sample. The collected sample is then transferred through an internal conduit to the sampler's main body for subsequent processing or analysis. This component is available in stainless steel 316L (ASTM A276) as standard, with optional Hastelloy C-276 for corrosive environments. Key parameters include probe length (300–2000 mm, custom lengths available), probe diameter (25–50 mm, affecting insertion strength), operating temperature (-40 to 200 °C, higher temperatures require cooling), operating pressure (1.0–1.6 MPa,), sealing class ( Cat. A, zero leakage at rated pressure), surface finish (0.4–0.8 μm Ra, smoother for hygienic applications), response time (1–5 s, depends on actuator speed), electrical connection (24 V DC ±10%, for solenoid actuation), ingress protection (IP54–IP65, higher IP for washdown areas), and weight (2–8 kg, depends on length and material). These values are directory reference ranges and must be confirmed for the specific model and application. The probe is designed for use in automated sampling systems and is not a standalone product. Always verify model-specific values and standards with the legal manufacturer or supplier.
