Sanitary / Hygienic Pressure Gauge Tri-Clamp Connection

-- Steady & Reliable Manufacturer --

Product Overview

Our Sanitary Pressure Gauges are specifically designed for food & beverage, dairy, brewery, pharmaceutical, and biotechnology applications where product purity, cleanability, and regulatory compliance are non-negotiable requirements. The defining feature is the Tri-Clamp (TC) process connection — conforming to ISO 2852 and 3A sanitary standards — which provides a crevice-free, drainable, and easily disassembled interface to hygienic process piping. The internal wetted path is manufactured from electropolished stainless steel 316L (Ra ≤ 0.8 μm), preventing product adhesion and bacterial growth, while supporting full clean-in-place (CIP) and sterilization-in-place (SIP) cycles without removal of the gauge from the line.

Key Features

Tri-Clamp (TC) process connection conforms to ISO 2852 and 3-A Sanitary Standards 85-02, ensuring direct compatibility with hygienic pipeline systems in food, dairy, brewery, and pharmaceutical plants worldwide.
Electropolished 316L stainless steel wetted surface (Ra ≤ 0.8 μm standard) prevents product adhesion, facilitates complete drainage, and resists bacterial biofilm formation between CIP cycles.
Food-grade fill medium (NSF H1 certified food-grade oil or food-grade glycerin) ensures no risk of product contamination in the event of minor seal weeping at the diaphragm or Bourdon tube connection.

Typical Use Cases

Dairy Processing: Milk, cream, and whey line pressure monitoring on pasteurizers, separators, and homogenizers with full CIP compatibility.
Brewery & Fermentation: Fermentation vessel, bright beer tank, and carbonation pressure monitoring requiring hygienic connections and easy disassembly for cleaning.
Pharmaceutical Bioreactors: Sterile process pressure indication on fermenters, media preparation vessels, and clean utility systems under GMP regulations.
Juice & Beverage Production: Filling line and pasteurization tunnel pressure monitoring where product contact surfaces must meet EC 1935/2004 food contact compliance.
Cosmetics & Personal Care: Hygienic pressure monitoring on cream, lotion, and emulsion processing vessels requiring regular SIP steam sterilization cycles.

Competitive Benefits

Certified Hygienic Design: 3-A Sanitary Standard 85-02 compliance provides regulatory assurance for FDA inspections and FSMA audits, eliminating the need for custom hygienic validation of instrument interfaces.
Tool-Free Disassembly: The Tri-Clamp ferrule and clamp connection can be disassembled and reassembled in seconds without tools, enabling rapid gauge removal for offline calibration and simplified maintenance scheduling.
Full CIP/SIP Compatibility: The gauge withstands repeat CIP cycles (caustic + acid wash) and SIP steam sterilization at 150°C without degradation of the wetted surface finish or seal integrity.
No Dead Zones: The self-draining Tri-Clamp connection geometry leaves no residual product pockets that could harbor bacteria or cause cross-contamination between batches.
NSF-Certified Fill Medium: The optional NSF H1 food-grade oil fill (incidental food contact approved) eliminates the risk of recall or product rejection due to gauge fill fluid contamination.

Payment and Shipping Details

We accept T/T, L/C at sight, and Western Union for international orders. Standard shipping is FOB Shanghai/Ningbo or CIF destination port. Standard Tri-Clamp gauges (1" to 2" TC, common ranges 0–6 bar and 0–16 bar) ship within 10–15 working days. Gauges with Ra ≤ 0.4 μm mirror-polished wetted parts, 3-A documentation, or NSF-certified fill medium require 20–25 working days. All gauges are supplied in clean, dust-free packaging with wetted connections capped to maintain surface cleanliness during transit.
