Description

Double-Polished Borosilicate Sight Glass for Precision Level Gauges and Instrumentation


1. Material Composition:

  • Borosilicate Glass: High-purity, low-thermal-expansion material (e.g., Schott B270 or Pyrex equivalent) ensuring chemical inertness and structural stability.

  • Double-Polished Surfaces: Precision grinding and polishing on both sides for exceptional optical clarity, minimal light scattering, and distortion-free visualization.


2. Key Properties:

  • Thermal Resistance: Withstands temperatures up to 450°C (continuous) and thermal shock differentials exceeding 150°C.

  • Mechanical Durability: Hardness of 6.5 Mohs and pressure resistance up to 10 bar (customizable for higher specs).

  • Chemical Inertness: Resists corrosion from acids, alkalis, and solvents (excluding HF).

  • Optical Performance: >92% light transmission with UV to IR compatibility (280nm–2.5μm).


3. Core Functions:

  • Precision Monitoring: Enables accurate visual inspection of fluid levels, colors, and phases in gauges and instruments.

  • Safety Barrier: Acts as a transparent seal for high-pressure or hazardous environments (e.g., steam boilers, chemical tanks).

  • Optical Interface: Facilitates laser or spectroscopic measurements in analytical instrumentation.


4. Applications:

    • Industrial Level Gauges: Used in boilers, reactors, and pipelines for exact liquid/interface monitoring.

    • Process Instrumentation: Integrated into flow meters, pressure vessels, and control systems.

    • Laboratory Equipment: Employed in autoclaves, environmental chambers, and precision sensors.

    • Energy & Pharma: Suitable for solar thermal systems, pharmaceutical tanks, and sterilizable viewports.
