Product Description
Key Characteristics & Construction
Sensing Element: A thin, circular, corrugated metal or polymer disc (such as stainless steel, Hastelloy, or PTFE-lined) clamped or welded between two flanges.
Isolation Barrier: Completely separates the process fluid from the sensitive internal mechanical movement or fill fluid, preventing clogging or corrosion.
Operation Modes: Can function via direct mechanical linkage (push rod and gear mechanism) or indirectly via a sealed hydraulic fill fluid communicating with a secondary gauge element.
Common Applications
Chemical & Petrochemical: Handling toxic, corrosive, or adhesive liquids.
Food & Pharmaceutical: Providing clean, flush connections that eliminate dead space for safe sterilization.
Low-Pressure Systems: Highly sensitive surface area allows accurate readings starting down to 1016 mbar.

Precise Low-Pressure Measurement
Engineered for a 0-400 mbar range, the diaphragm-type pressure gauge provides CL 1.6 accuracy and a 1 mbar graduation, allowing for fine, stable readings critical for sensitive processes and safety monitoring.
Adaptable Installation Options
With direct or flange mounting and a variety of process connections-including standard 1/2 BSP/NPT threads-this gauge integrates seamlessly into both new builds and retrofit applications, delivering flexibility for various setups.
FAQ's of PRESSURE GAUGE DIPHRAGM:
Q: How can the pressure gauge diaphragm be used with aggressive or viscous media?
A: The pressure gauge is designed with 316L stainless steel wetted parts and an Inconel 718 diaphragm, making it highly compatible with aggressive, viscous, or crystallizing media. This construction prevents clogging and chemical corrosion, ensuring stable, long-term operation even in demanding applications.
Q: What benefits does the pressure gauge offer for industrial process monitoring?
A: The gauge provides reliable, accurate measurements (CL 1.6) across a 0-400 mbar range, essential for monitoring sensitive processes. Its robust overpressure safety (up to 2000 mbar) and long-term stability reduce maintenance needs while supporting consistent process control in industrial settings.
Q: Where can the diaphragm type pressure gauge be installed?
A: With options for direct mounting, flange mounting, and multiple process connections-including threaded adapters-the gauge can be installed in a variety of locations, such as pipelines, tanks, or chemical reactors. Its IP54 protection ensures suitability for general industrial environments.
Q: When should this pressure gauge be selected instead of a traditional bourdon tube model?
A: Choose this diaphragm type gauge when dealing with low-pressure ranges (0-400 mbar), aggressive or viscous media, or processes where media crystallization or clogging could occur. Its construction and measurement technology outperform traditional bourdon tubes in these conditions.
Q: What is the typical process for connecting and commissioning this gauge?
A: Installation involves securing the gauge to the process line using either the flange or threaded adapter, ensuring a proper seal to prevent leaks. Once mounted, the dial offers instantaneous readings without external power, and no calibration is usually required before use, streamlining commissioning.
Q: How does the IP54 protection rating benefit the gauge's usage?
A: IP54 indicates protection against dust ingress and water splashes, making the gauge suitable for use in industrial environments where exposure to such elements is common. This enhances the device's longevity and reliability during regular operations.
