Brookfield Engineering is a measurement and analysis equipment manufacturer based in Middleboro , Massachusetts . Its product line includes viscometers , rheometers , texture analyzers , powder flow testers and process instrumentation . These devices are used in research, development and control technology . The company became known outside of professional circles for the allegation that it caused severe environmental pollution through toxic waste .
Brookfield Engineering sells its products in 60 countries and has offices in the United States , United Kingdom , Germany , India and the People's Republic of China . It is produced exclusively in the USA.
Company history
During his training at the Massachusetts Institute of Technology , Don Brookfield Senior developed and sold his first self-developed viscometer. After successfully completing his studies, he worked at Gilette and further developed the device that was to become the industry standard for viscosity measurement. From 1937 he worked full-time for his own company, Brookfield Engineering Laboratories, which he founded with his father and brothers.
Brookfield Engineering was a family company until 1986; thereafter, other employees were also involved in the company. The company's quality management has been ISO 9001 certified since the 1990s .
Working principle
Classic Brookfield viscometers are rotational viscometers : a disc is rotated by a motor in the liquid to be tested. During the rotation, the required torque is measured by the evasion of a spring . When a Newtonian fluid is measured, its viscosity can be derived from it. This test method measures viscosity in a low shear rate range. P. 254 If the fluid is non-Newtonian, Brookfield viscosities can still be compared to determine deviations from standard values. The rheological properties of a test fluid can be examined by measuring the same disk at different speeds. Accurate comparisons are only useful if the same disc, rotational speed, spring, temperature, container size, test duration and other sample preparation procedures are used. When developing new test methods, the speed and pulley must be selected empirically more often so that the spring deflection always remains between 10 and 100%.
Today, in addition to its classic viscometers, Brookfield also produces rheometers that enable precise rheological measurements of non-Newtonian substances.
The classic Brookfield viscometer, despite its shortcomings, is widely used and is part of various standards. P. 270 p. 237
environmental pollution
In 1998, the Massachusetts Department of Environmental Protection evacuated residents of Stoughton after a solvent exposure limit was found to be exceeded. Brookfield Engineering was suspected of causing the pollution. The company took over evacuation costs and environmental cleaning costs without recognizing any liability. The Boston Globe newspaper called it " one of the state's most unusual and serious problems of residential toxic-waste contamination " ( one of the most unusual and serious problems of residential toxic-waste contamination [in Massachusetts]).
