How to specify an ATEX explosion-proof light for your sight glass

How to specify an ATEX explosion-proof light for your sight glass

The many ratings and standards bodies can be a confusing alphabet soup of acronyms… ATEX, UL, NEC, IEC, IP and NEMA. When is ATEX the right one? If you are considering an ATEX explosion-proof light for your sight glass, then you already know that a light with an ATEX rating will be safe to operate in a potentially explosive atmosphere. First, forget about IP and NEMA ratings. Those define housings. For example,

What is First-Indication Flow Rate?

Standard flanged industrial sight flow indicatorA common question that I hear is, “what is the first-indication flow rate?”

Sight flow indicators are a fail proof means of observing flow within a process pipeline. To make it easier to see the flow, often a mechanical indicator is added behind the window… a spinning rotor for example. What people are asking is, what is the minimum flow needed to move the indicator?

Why Preventing Sanitary Clamp Galling Is Crucial to Product Purity

Why Preventing Sanitary Clamp Galling Is Crucial to Product Purity by Michael Curnutte All makers of pharmaceuticals and biotechnology products have many concerns in common, but none is more critical than maintaining tight control over product purity during manufacturing and packaging. For example, if contamination were to compromise the integrity of a single batch of insulin, it could easily mean a loss of hundreds of thousands or millions of dollars in revenue to the manufacturer.

Where can I find a sanitary fitting for a botanical oil extractor?

stinging nettle leaves in a glass funnel above a pharmacy bottle, a medicinal herb for tincture, essence or tea, isolated on a white background, vertical The medicinal use of cannabis is becoming normalized in a growing number of states. Some of the products used include botanical oils. The botanical oil extraction process relies on pressure and solvents generally recognized as safe by the FDA. CO2 and hydrocarbon solvents such as butane or propane are the most common. Systems that use nButane work at relatively low pressures in the range of 80 to 150 psi. CO2 systems operate at higher pressures up to 5000 psi. Obviously, a failure at these pressures can be dangerous to workers, and natural gas products also carry the risk of fire and explosion.

Sight Glass Light Options for Conical Fermenters

Like other critical components of getting the perfect brew, conical fermenters need to be closely observed. Fermentation is part art, which means you need to involve your senses: seeing, smelling, tasting. It’s also part science, which means that you need a way to confirm that each stage of the process is going according to plan: that the cleaning solution is fully rinsed, that there is no cross batch contamination, etc.  In short, you need a sight glass window on your vessel, and a light to illuminate its interior.
brewing fermenter sight glass lights Conical fermenter sight glass lights come in various types and configurations. In my post today I’ll review some of your options, so you can choose the optimal light for your situation. By the way, although I’m focusing on fermenters, which may be conical or straight, the same advice will apply to any brewing equipment vessel, including mash lauter tuns, finishing tanks, and the like.

LED lighting for food & beverage sight glass applications

Food and Beverage ApplicationExperts in the $738 billion food and beverage manufacturing industry know that, for consumers, taste begins with the eyes. This is especially true with beverages, for whom hue, clarity, cloudiness, transparency, opacity and foam are very tightly controlled. Such the domain of the processing engineer, who depends on the sight glass and associated lighting to observe the process media.

How to Size a Sight Glass Light for a Process Vessel?

Sight Glass Light diagram for process vessel             Ah, the world of lighting used to be so simple. When you needed to illuminate the interior of a process vessel or tank, you selected a halogen light by its watts. Typically you used a 50 watt light because that’s what the manufacturers commonly offered. If that wasn’t bright enough, then you used a 100 watt light. It got hot, but you didn’t have much choice. The decision for your sight glass light was simple.
