Our 6-inch (150mm) Sanitary Pressure Gauge represents the pinnacle of hygienic industrial instrumentation. Featuring a diaphragm seal type design with a flush-mounted sanitary flange, this all-stainless steel gauge is specifically engineered for applications where cleanliness, corrosion resistance, and easy cleaning are paramount. With a 0-1MPa range and built-in vibration resistance, this pressure gauge with flange is the optimal solution for food & beverage, pharmaceutical, biotechnology, and chemical processing industries.

Sanitary Diaphragm Seal Design: As a true diaphragm type pressure gauge, it features a flexible diaphragm that isolates the gauge mechanism from the process media. This prevents clogging, allows measurement of viscous or crystallizing fluids, and enables thorough cleaning without damaging the internal movement.
Hygienic Flange Connection: The sanitary pressure gauge comes with a standard tri-clamp or flange connection (typically 1.5", 2", or 3" flange), enabling quick installation, removal, and cleaning—essential for CIP (Clean-in-Place) and SIP (Sterilize-in-Place) processes.
Full Stainless Steel Construction: Entirely constructed from 316L/304 stainless steel, including the case, diaphragm, flange, and wetted parts. This ensures complete corrosion resistance and compliance with sanitary standards.
Excellent Vibration Resistance: The diaphragm seal design and robust construction inherently dampen process pulsation and vibration, providing a stable, readable indication even on pumps and agitators.
Superior Readability: The large 6-inch (150mm) dial allows for clear, precise readings from a distance, crucial for monitoring in large production facilities.

Unlike standard pressure gauge with flange designs that merely add a mounting plate, our diaphragm seal type pressure gauge offers distinct advantages for demanding industries:
Process Isolation: Protects the sensitive Bourdon tube from corrosive, viscous, or high-temperature media.
Zero Process Dead Leg: The flush diaphragm design eliminates areas where product can accumulate, preventing bacterial growth—a critical feature for a sanitary pressure gauge.
Easy Maintenance: The gauge can be removed for calibration without draining the process line, and the diaphragm can be replaced if damaged.
Enhanced Safety: Contains the process media safely behind the diaphragm, even in case of overpressure.

This specialized gauge is essential for:
Food & Beverage Processing: Dairy, brewing, sauce production
Pharmaceutical & Biotechnology: Fermenters, bioreactors, purification systems
Cosmetics & Personal Care: Mixing vessels, filling lines
Chemical Processing: Corrosive or abrasive fluid handling
Pulp & Paper Industry: Chemical additive systems
Proper selection of diaphragm material, flange type, and process connections is crucial for optimal performance. Our engineering team provides expert configuration support.
