PL20H

🧪 What This Data Means — For Quick Client Selection

✔ Hygienic-grade for food & pharma

Its polished 316L stainless steel body and hygiene approvals make it suitable for milk, whey, beer, beverages, WFI, APIs, and other sanitary media.

✔ Works even in foam / sticky fluids

Capacitive technology automatically compensates for coatings, foams, syrups, gels, creams, and viscous products — ideal for hygienic tanks and mixers.

✔ CIP/SIP ready

With up to 140 °C tolerance, the PL20H handles hot cleaning cycles — critical for breweries, dairy plants, pharma reactors, and filling machines.

✔ IO-Link smart functionality

Enables digital configuration, remote diagnostics, switching-point adjustment, and batch traceability — preferred in automated OEM systems.

✔ Compact for tight installations

Short insertion depth and multiple hygienic process connections allow installation in small tanks, pipelines, filling heads, and skids.

✔ Fast detection

Quick switching enables filling accuracy, pump protection, valve control, and high-speed packaging operations.

✔ Ideal for:

  • Dairy processing (milk tanks, separators, pasteurizers)

  • Beverage lines (breweries, carbonated drinks, juice plants)

  • Pharma mixing tanks & reactors

  • CIP/SIP systems

  • Viscous media like sauces, creams, gels

  • OEM hygienic filling & dosing machines
