Sight Glass Light Measurement and Sizing Guide


Optimize Brightness in Your Process Vessel

Thorough visibility ensures safety, efficiency and quality control in pharmaceutical, biotech and industrial processing. But do you have the right lighting setup to maximize visibility?

The white paper, Sight Glass Light Measurement and Sizing Guide, provides expert insights on how to size the best sight glass lighting solution for your specific application.

What You’ll Learn from This Guide:

  • The difference between halogen and LED lighting - Learn which type has higher brightness
  • How light impacts process observation – Discover how light intensity, angle, and vessel dimensions determine how well you see
  • How to measure light transmission – Determining luminance from a vessel
  • How human perception affects visibility – Excess brightness does not improve visibility
  • Minimum threshold for illuminance – Lighting intensity to see fine detail
  • Recommended light sizing - For different sizes and types of vessels.

Improve your process monitoring. Ensure clear observation of your system to detect contamination, leaks or inconsistencies

Download the Sight Glass Light Measurement and Sizing Guide white paper and properly illuminate your process vessels.
