Sanitary Clamp Pressure Gauge

Pressure Gauges

The Sanitary Clamp Pressure Gauge is a specialized measuring instrument designed for industries with the most stringent hygiene and cleanliness requirements. By utilizing a Tri-Clamp (Quick-Release) connection and a flush-mounted diaphragm seal, the gauge ensures there are no dead spaces or "cold spots" where bacteria or process media can accumulate. The measuring system is completely isolated from the medium by a high-grade stainless steel or exotic alloy diaphragm. This design makes it the industry standard for measuring viscous, corrosive, or high-purity media in the food, pharmaceutical, and biotechnology sectors.

Description

Overview of Sanitary Clamp Pressure Gauge

The Sanitary Clamp Pressure Gauge combines the precision of a Bourdon tube gauge (or transmitter) with a hygienic diaphragm seal interface.

What is it? It is a diaphragm-sealed system where the internal sensing element is protected by a flexible metal membrane. The space between the membrane and the gauge is filled with a food-safe transmission fluid. When process pressure acts on the membrane, it is transmitted through the fluid to the gauge movement.
Main Application Field: Engineered specifically for the food, beverage, pharmaceutical, chemical, and bioengineering industries. It is ideally suited for viscous media (like syrups or creams) and corrosive fluids that require frequent cleaning (CIP/SIP).
Key Characteristics: The quick-release clamp connection (sizes 3/4" to 3") allows for rapid installation and removal without tools, facilitating easy inspection and sterilization of the process lines.

Features of Sanitary Clamp Pressure Gauge

Hygienic Flush Design: The flush diaphragm prevents media buildup and ensures easy cleaning, supporting CIP (Clean-in-Place) and SIP (Steam-in-Place) processes.
Premium Material Options: Wetted parts are standard in 316L Stainless Steel, with options for Hastelloy, Monel, Platinum, Titanium, or Tantalum for extreme chemical resistance.
Leak-Proof Isolation: The isolated diaphragm structure ensures that process media never comes into contact with the internal gauge mechanism, preventing contamination.
Versatile Process Connections: Available with standard Tri-Clamp sizes from 3/4" up to 3", ensuring compatibility with international sanitary piping standards.
Customizable Pressure Ranges: Diaphragm bodies can be engineered to handle various pressure ranges according to specific customer requirements.
High-Precision Polishing: Optional electropolishing is available to achieve an ultra-smooth surface finish (Ra < 0.4μm), reducing the risk of bacterial adhesion.

Applications of Sanitary Clamp Pressure Gauge

Dairy & Beverage: Monitoring pressure in milk pasteurization, brewery fermentation tanks, and soft drink carbonation lines.
Pharmaceutical Production: Pressure control in bioreactors, filtration systems, and sterile filling lines.
Biotechnology: Monitoring sensitive cell culture environments where zero contamination is mandatory.
Viscous Media Handling: Measuring the pressure of chocolate, honey, ointments, or heavy chemical pastes that would clog standard gauges.
Corrosive Processing: Used in chemical dosing lines where aggressive cleaning agents or corrosive ingredients are present.

Advanced Configuration Options (OEM)

ZINACA Instrument provides high-value accessories to adapt the sanitary gauge to extreme conditions:

Cooling Elements: Siphons (pigtails) or radiators for high-temperature media (> 100°C).

Remote Monitoring: Capillary tubes for remote mounting away from heat or vibration.

Safety & Stability: Integrated Dampers for pulsating flow and Overpressure Protectors to prevent diaphragm damage.

Chemical Barriers: Special coatings (e.g., PTFE) on the diaphragm for aggressive chemical media.
