Key Features and Advantages

• Full Visual Clarity: Provides a true, undistorted view of the liquid, enabling precise observation of its physical properties, color changes, and interface layers between different fluids.
• Superior Chemical Resistance: Made from Borosilicate Glass 3.3, offering excellent resistance to a wide range of acids, alkalis, and other aggressive process fluids, ensuring longevity and integrity.
• High-Pressure & High-Temperature Performance:

Maximum Service Temperature Up to 400°C (depending on operating conditions)

Maximum Working Pressure Up to 340 bar (depending on glass size, medium and temperature)

• Universal Standard Compliance: Our transparent gauge glasses are precisely manufactured to comply with global dimensional and performance standards, making them ideal for new installations or as direct replacements in existing gauge assemblies.

Industrial Applications

Transparent gauge glasses are the preferred choice for demanding applications where detailed visual inspection of the process media is critical, especially in the presence of steam or corrosive substances.

• Steam Boilers: Essential for high-pressure steam applications, particularly when protected by mica shields, to prevent glass etching and ensure safe operation.
• Chemical Processing: Monitoring corrosive liquids, chemical reactions, and interface levels in reactors and storage tanks.
• Petrochemical Industry: Observing crude oil, refined products, and various hydrocarbons where color and clarity are important indicators.
• Pharmaceutical & Food & Beverage: Maintaining hygienic conditions and visually confirming product quality and separation in sanitary processes.
• Any application requiring full visibility: Where reflex glass's black/silver indication is insufficient for process control.

Frequently Asked Questions (FAQ)

Q: When should I choose Transparent Gauge Glass over Reflex Gauge Glass?

A: Choose transparent gauge glass when you need to observe the actual color, clarity, or interface of the liquid, or when the liquid is dirty/turbid. It is also mandatory for high-pressure steam applications (typically above 35-40 bar) where mica shields are required to protect the glass from etching. Reflex glass is generally preferred for clear, colorless liquids where a distinct black/silver contrast is sufficient.

Q: What is a mica shield and why is it used with Transparent Gauge Glass?

A: A mica shield is a thin, transparent sheet of natural mica (a mineral) placed between the transparent gauge glass and the process fluid. It protects the glass from the corrosive and erosive effects of hot steam and aggressive chemicals, significantly extending the lifespan of the gauge glass and enhancing safety.

Q: Are your transparent gauge glasses compatible with existing gauge bodies?

A: Yes, our transparent gauge glasses are manufactured to precise international dimensional standards (e.g., DIN 7081), ensuring they are fully compatible with most standard armored level gauge bodies from various manufacturers worldwide. They serve as reliable, high-quality replacement components.

Q: Can I customise the size of the reflex gauge glass I need or print my own logo on it?

A: We have stock of standard sized reflex gauge glass and can also customise sizes to meet most of your requirements, including printing logos and customizing outer packaging.
