Key Features and Advantages

• Exceptional Thermal and Chemical Resistance: Made from high-grade borosilicate glass 3.3, these lenses offer outstanding resistance to thermal shock, alkalis, acids, and boiler water, ensuring a long service life even in harsh chemical processing environments.
• High-Pressure Capability: Designed to withstand extreme pressures, our reflex glasses are suitable for service conditions up to 400 bar (depending on the specific size and operating temperature), providing a safe barrier between the operator and the process media.
• High-Contrast Reflex Principle: The precisely ground prism grooves create a sharp, unmistakable black-and-silver contrast between liquid and vapor phases, enabling instant and accurate liquid level assessment from a distance.
• DIN 7081 Compliance: Manufactured and tested in strict accordance with DIN 7081, guaranteeing adherence to international standards for dimensions, material quality, pressure resistance, and safety for gauge glasses.
• Universal Compatibility: Our glasses are dimensionally precise and compatible with most standard armored liquid level gauge bodies worldwide, serving as reliable replacement parts for existing installations.

Industrial Applications

Reflex gauge glasses are the industry standard for direct-reading level indicators where clear visibility and safety are paramount. They are widely utilized across various sectors that handle hazardous, high-temperature, or high-pressure fluids.

• Oil and Gas Refineries: Monitoring levels in separators, distillation columns, and storage tanks.
• Chemical and Petrochemical Plants: Safe observation of corrosive liquids and chemical reactions in process vessels.
• Power Generation: Critical for monitoring water levels in steam boilers and feedwater heaters to prevent catastrophic failures.
• Pharmaceutical and Food Processing: Ensuring precise liquid volume control in sanitary and hygienic manufacturing environments.

Frequently Asked Questions (FAQ)

Q: What is the difference between Reflex and Transparent gauge glass?

A: Reflex glass has prismatic grooves on the liquid side, making the liquid appear black and the gas appear silver, which is ideal for clear liquids. Transparent glass is smooth on both sides and is used with an illuminator to view the color, interface, or particulate matter within the fluid.

Q: Are your Borosilicate Reflex Gauge Glasses compatible with my existing gauge bodies?

A: Yes, our Borosilicate Reflex Gauge Glasses are manufactured to precise international dimensional standards (DIN 7081), and material (Borosilicate Glass 3.3). They are fully compatible with most standard armoured level gauge bodies from various manufacturers worldwide and can be used as high-quality, reliable replacement parts for your existing level gauge assemblies.

Q: Are reflex gauge glasses suitable for high-pressure steam applications?

A: While highly durable, reflex gauge glasses are generally recommended for steam applications up to a certain pressure limit (typically around 35-40 bar). For extremely high-pressure steam, transparent gauge glasses protected by mica shields are often required to prevent the glass from being etched by the steam.

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.
