Food and Beverage Flow Sights

Made of FDA-listed materials for use with food and beverage, these sights have sanitary quick-clamp connections and an electropolished 316 stainless steel body for easy disassembly and cleaning. They meet USP (United States Pharmacopeia) Class IV standard for food applications. Sights let you visually confirm flow and inspect liquid color and clarity. Backlight the back window to increase the visibility of dark liquids.

Sights for Quick-Clamp Sanitary Tube Fittings

Sight Shown Assembled

With Gasket, Quick-Clamp

Fitting, And Tube

Fitting (All Sold

Separately)

Monitor food, brewery, chemical, pharmaceutical, and biotech processing lines with these sights that attach to quick-clamp fittings for fast installation and easy removal for cleaning. All have a one-piece design, so there are no crevices where bacteria can grow. A quick-clamp fitting, gasket, and tube fitting are required (sold separately).

2205 Stainless Steel with Glass Window

For superior strength and reliability, choose 2205 stainless steel sights. All have a glass window that’s melted around a high-strength ring, so they won’t shatter, leak, or lose their shape under high pressure, heat, chemicals, or impact. They withstand harsh cleaners and sanitizers for clean-in-place (CIP) and steam-in-place (SIP) applications. USP Class VI and TUV Rheinland Certified, these sights meet safety standards in the U.S. and Europe. They also meet DIN standards for glass materials used in sights, ASTM standards for materials used in boilers and pressure vessels, and ASME BPE design standards for bioprocessing equipment that ensure purity and safety.

Sanitary RTD Probe Transmitters with Digital Display for Liquids and Gas

Check the temperature of liquids in hygienic applications such as food or pharmaceutical lines and tanks. Certified by 3-A to meet sanitary design standards, the parts of these probes that will touch liquid are highly polished to minimize spots where bacteria could grow. They're made of stainless steel, so they won't corrode from harsh cleaners and sanitizers. The housing is IP69K rated, meaning it withstands high-pressure, high-temperature washdowns that are common in hygienic cleaning practices. They have a flange that will connect to sanitary quick clamp fittings (also known as tri-clamp fittings); they're easy to connect and remove from your line.

Program these probes with the touchscreen, and select one of three colors as a visual alert for events in your process such as irregular or fluctuating temperatures. The head swivels 345° and the face rotates all the way around, so you can mount the sensor at any angle and still see the display. To trigger actions in your process line, connect these probes to remote displays, programmable logic controllers (PLCs), and other control equipment with the M12 plug. These probes meet EN 60751, an industry standard for accuracy. They’re also CE marked, meaning they meet European Union safety standards.
