Carl A. Vossberg, Jr. |
His biography reveals how his dedication to industrial refractometry led Electron Machine to its leadership position in the industrial refractometer market.
Carl A. Vossberg, Jr., (born July 16, 1918) was an American electrical engineer, inventor, and entrepreneur in the electronic instrumentation industry. He is known for more than 30 technical patents in the area of refractometry, measurement, and control. Vossberg also founded Electron-Machine Corporation, the company responsible for the introduction of inline process refractometers as a measuring system for the pulp & paper, food, and chemical processing industries.
Vossberg began his college education at the City College of the City of New York (CCNY), studying electronics, and was awarded a BEE in Electrical Engineering from CCNY and a MS in Electrical Engineering (EE) from Columbia University. He also attended Massachusetts Institute of Technology. During WWII, Vossberg worked for the U.S. Office of Strategic Service (now CIA) participating in the development of remote radio transponders, artillery tracking systems, weapon fire detection controllers, and video transmission.
Vossberg entered the profession as a radio engineer for RCA and designed circuits and established radio facsimile facilities for the Office of War information. Later he became Chief Engineer for Standard Electronics Research Corporation, where his duties were to originate and direct the research and development programs and supervise engineering and technical personnel in electronics, x-rays, communication, instrumentation and process controls. He was also Vice President of Research and Developments, Inc., and Vice President of Industrial Gauges Corporation.
After the war, Vossberg set out to apply electronics technology to industrial applications. Electron Machine Corporation was formed in 1946 for the purpose of designing automatic electronic gaging and indicating equipment. The company was established in the back of a radiator repair shop in Lynbrook, New York. Instruments for diameter and thickness measurements for steel and cable products were conceived, developed, and licensed to other manufacturers. These instruments included the first commercial x-ray thickness gage, optical cable diameter gages, and an industrial process control computer. In 1950 he, in partnership, formed the Industrial Gauges Corporation and later established Research Developments, Inc., as a subsidiary. This expansion provided the manufacturing facilities for the products developed by the Electron Machine Company.
Engineering, manufacturing and design continues today with the third generation of Vossberg leadership. As a vertically-integrated manufacturer, Electron Machine continues the Founder's legacy of manufacturing inline industrial refractometers that solve the most challenging industrial applications while providing the highest levels of service and support to customers.
Industrial Refractometry: The Very Basics
If you’ve ever cracked open a crisp, cold beer on a Sunday, sampled a great wine, or asked yourself, “why does this soda taste so good?” you’ve had experience with what the process control industry calls “industrial refractometry.” Pink Floyd’s album cover for Dark Side of the Moon, where a beam of light hits a prism at a certain angle and then exits the other side in multiple colors, illustrates a core component of refractometry. Refractometry measures the speed at which light passes through an object.
Here’s how evaluating a substance with a refractometer works: a substance is placed on top of a prism. Then, a beam of light shines through the prism and reflects through the substance. The refractometer compares how much slower (or faster) light travels through the object compared to the speed of light through air. The comparison allows the evaluator to determine qualitative aspects of the substance, such as the density or concentration. For standardization purposes, the speed at which light passes through air has a refractive index (RI) value of 1. If a substance has an RI value of 1.16, light travels 16% quicker through air compared to the substance on the prism. Depending on the color and temperature of the reflected light, even more qualitative characteristics of the substance can be determined.

While the process won’t always help determine what exactly a substance is (different substances can have the same RI values), refractometry is essential in determining how something is. If a corporation knows the RI value of a liquid product, they can ensure each iteration of said product is precisely made, quantitatively and qualitatively. When two substances are being combined to create one resulting substance, refractometry can show exactly how close the combined substance is to being an accurate fusion.
Overall, refractometry is used by industrial companies as a control method. Industry professionals use refractometers to perform evaluations; these refractometers range from small, hand-held devices to full-powered, computer-controlled precision machines which measure the quality of every product coming out of on an assembly line. Refractometry is an objective way to prove standards are being met while achieving production excellence, making refractometry an extremely valuable tool for industrially geared businesses of almost every size.
So, the next time you want to combine coffee and creamer, if you know the refractive value of the best cup of coffee, you could use your own refractometer to measure how close you are to the perfect morning blend!
Refractometry: A Basic Understanding and Common Uses

Other common examples of industrial refractometry uses are measuring the salinity of water to determine drinkability; figuring beverages’ ratios of sugar content versus other sweeteners or water; setting eye-glass prescriptions; understanding the hydrocarbon content of motor fuels; totaling plasma protein in blood samples; and quantifying the concentration of maple syrup. Regarding fuels, refractometry scrutinizes the possible output of energy and conductivity, and for drug-testing purposes, refractometry measures the specific gravity, or the density, of human urine. Regarding food, refractometry has the ability to measure the glucose in fruit during the fermentation process. Because of this, those in food services know when fruit is at peak ripeness and, in turn, also understand the most advantageous point in the fruit’s “lifetime” to put it on the market.
The determination of the substance composition of the product examples listed above all speak to the purpose of quality control and the upholding of standardized guidelines; consumers rely on manufacturers not only to produce these products but also to produce these products consistently and identically every single time. Therefore, the success of commercialism, etc. is dependent on maintaining the standards for the composition of substances, i.e. industrial refractometry.
Equipment manufacturers have developed numerous refractometer configurations tailored to specific use and application. Each has a set of features making it the advantageous choice for its intended application.
MPR- E-Scan Inline Refractometer Settings and Readings Overview
The MPR E-Scan is an in-line process refractometer that directly measures the refractive index of process fluids and then displays the reading in any number of customer-desired units (Brix, Percent Solids, Dissolved Solids, SGU, R.I., etc.). A simple 0-10Vdc signal is used to transmit the reading from the sensing head to the electronics console, ensuring a robust reading that has a minimal chance of being effected by interference. The entire package is NEMA 4X rated and designed and manufactured with the best materials for each application to provide years of trouble-free service with a minimum amount of maintenance.
