Opening Up Measurement Capabilities in Dairies, Breweries and More

Traditionally playing in oil and gas and chemical industries, Vega is making a move to a wide range of food and beverage applications with its new pressure and level sensors.

As a company focused primarily on the chemical and oil and gas industries, Vega has had little visibility in the food and beverage sector. “We have innovated for very specific markets,” noted Scott Rollman, director of sales for Vega Americas. Though food and beverage and pharmaceuticals are big industries, he added, “we have a very, very low market share in these industries today. We didn’t focus on them; we didn’t innovate for those industries. That’s something that’s changed dramatically.”

Speaking at a recent event near Chicago, Vega personnel introduced several new devices to a team of representatives from Enpro, a process instrumentation sales company that works in partnership with Vega Americas. In addition to introducing devices focused on replacing ultrasonic applications with radar technology, Vega made a case for its increased foray into the food and beverage industry.

With the plics instrument platform that Vega introduced in 2003—providing flexibility with very easily interchangeable devices—the company found applications in big brewery vessels, for example, because it was an environment similar to the storage tanks in refineries or chemical plants. “But when you start getting on packaging lines, we weren’t addressing the majority of the applications,” Rollman said.

The environments start to change heading deeper into a food or beverage facility, Rollman noted, but “measurements for pressure are repeated all throughout the plant.”

Vega is looking to change its history and get a stronger foothold in food and beverage. “You all have dairy in your territory,” said Greg Kline, food and beverage industry manager for Vega Americas, to the sales reps from Enpro. Traditionally, Vega’s sensors went only into large storage areas at the front of the dairy operations. “But in the process area, we didn’t have a lot of play. But that’s where we’re going to go today.”

As an example, Vega has a pressure device that’s very applicable for the dairy industry, for the heat exchanger where milk is pasteurized. “They have to be able to monitor the pressure not only of the milk, but of the steam coming in and the condensate going out,” Kline said.

With food and beverage applications in mind, Vega has expanded its measurement technology portfolio with two new series of compact pressure sensors and level switches for hygienic processes. New Vegabar pressure sensors can be provided with metallic or ceramic measuring cells, providing flexibility for hygienic applications. Vegapoint capacitive level switches come in various formats for water-based liquids, oils, and light bulk solids. Vegapoint 31, for light bulk solids, has potential for a number of point measurement applications, Kline noted, including large grain mills, flour mills, and feed bins.

“This opens us up to a new space that prior we didn’t have,” said Grant Cook, a sales engineer at Enpro. “For us, it’s an exciting prospect for existing customers that we’ve been servicing.”

The universal, flexible hygienic adapter system for the new series of instruments reduces the amount of work involved, and the required spare parts inventory.The universal, flexible hygienic adapter system for the new series of instruments reduces the amount of work involved, and the required spare parts inventory.VegaBoth the Vegabar and Vegapoint devices use a universal hygienic adapter system, which provides the flexibility to keep installation efforts and parts inventory to a minimum. Process fittings can be selected as needed to meet application-specific requirements.

The newest sensors have also been optimized for the food and beverage industry in terms of suitability for clean-in-place (CIP) and sterilization-in-place (SIP) applications. “They’re very hygienic as far as cleaning,” Kline said, noting also that compliance with 3-A sanitary standards is on its way. “And we will have all stainless-steel enclosures available by the end of 2020 for those who need it.”

Vegabar compact pressure sensors with switch function and Vegapoint capacitive level switches—both tailored to standard applications—feature a 360-degree status display, which can be set to any of 256 different colors and easily seen from any direction.Vegabar compact pressure sensors with switch function and Vegapoint capacitive level switches—both tailored to standard applications—feature a 360-degree status display, which can be set to any of 256 different colors and easily seen from any direction.VegaKline seemed particularly excited during his demonstrations about the fact that all the new pressure sensors and point level switches come standard with a 360-degree switching status display. The color of the illuminated ring can be customized with one of 256 different colors, all of which remain clearly visible, even in daylight. This lets users see quickly—at a glance, from any angle in a facility—when a process is running, if the sensor is switching, or if the sensor requires maintenance. In his demonstrations, Kline showed how the sensors could be programmed to change color depending on the presence of foam, a certain pressure level, point level, hydrostatic level—all kinds of possibilities.

“Now we have great quality, trendsetting innovation, and we can bring color into view,” Kline said.

Rollman made note of a dairy that Vega personnel had visited in Miami. “Everything is silver. Our competitors had little tiny LED lights,” he said, commenting on how close a technician had to get to see the status of those devices. “With ours, you could see them from a distance. The maintenance manager instantly knew what the status was.”

“There are neat things you can do with the colors,” added John Burnett, vice president of sales for Enpro. He noted how the colors could even be used to show what product is in a pipe at any given time.

Standard IO-Link protocol is also built into every pressure sensor and point level switch, providing a standardized communication platform that enables seamless data transfer and simple system integration.
