Cooper Instruments & Systems is pleased to serve clients around the globe, from the United States to Europe and Asia. Growth projections in Asia mean that they will be able to offer high-standard products more easily in the future.


Warrenton, VA (SBWire) July 8, 2014 – The IMF’s growth projections of 5.4% for 2014 and 5.5% for 2015 for Asia are beneficial for Cooper Instruments & Systems, as they will bolster the company’s finances and allow them to provide superior service for their clients around the globe.


“We couldn’t be happier with the projections in Asia,” a representative from Cooper Instruments & Systems reported. “It seems like 2015 will be a very positive year for us as a company, and this means that we’ll be able to expand and enhance our operations for all of our clients, no matter where they are located.”


It’s not just the growth projections that are giving Cooper Instruments & Systems something to celebrate. It’s also that vehicle sales in vital markets like China are booming. As Cooper Instruments & Systems works extensively with auto manufacturers and the auto industry, this means business will be better than ever.


“It’s good to know that more people around the world are owning cars,” the Cooper Instruments & Systems representative went on to say. “It’s not just that it’s good for our business, though; it’s a sure sign that the economy as a whole is improving, since more and more people can afford to buy vehicles. It’s a win-win situation for everybody, as far as we’re concerned.”


China’s automotive market growth is particularly impressive, as in 2013 it was the first nation to report over 20 million automotive units sold.


“Even more impressive is that, even with these remarkable numbers coming out of China, it still remains a nation with low car ownership over all,” the Cooper Instruments & Systems representative said. “There is lots of room for growth.”


It is estimated that there are only 120 million vehicles in China, which is extremely low for a country that has nearly a billion and a half people. Only time will tell where the Asian market will go, but Cooper Instruments & Systems is looking forward to the future, and will continue to serve its clients, both new and old, with diligence and care.

While there are different kinds of electrical circuits that load cells use, the most common configuration is known as the Wheatstone Bridge. One of our earlier blog posts (found here) discussed the Wheatstone bridge in detail. The Wheatstone Bridge configuration is the most popular, but there are a number of lesser-known bridges used in load cells as well. Most of these are simply alterations of the standard design, but they offer alternatives for different levels of resistance. Here is a look at some of the other popular bridge configurations:


Carey Foster Bridge. The Carey Foster Bridge is an electrical circuit that can be used to measure low resistances, or small differences between two larger resistances. It follows the same basic principles as the Wheatstone Bridge, but has a higher level of sensitivity.


Kelvin Bridge. The Kelvin Bridge is useful for measuring low values of resistance in industrial applications. This is a capability the Wheatstone Bridge does not have.


Kevin-Varley Divider. The Kevin-Varley Divider configuration is used to divide voltages and generate precise output data. It’s essentially a precise digital to analog converter.


Maxwell Bridge. The Maxwell Bridge is an AC bridge, meaning it has a balance detector and four arms. This configuration is useful for measuring the wide range of audio frequencies.


At Cooper Instruments & Systems, we offer a number of different load cells for various applications. Our load cells are made from quality materials for durability and reliability. Contact us today to find out how we can provide load cells for your business.


In 1921 and 1922, the Bureau went through some profound staffing changes, with 3 of its division chiefs dying in a span of 10 months. All 3 had been with the Bureau from the beginning, and its head, Dr. Stratton, had a bond with them that was not present with more recently acquired staff. Between losing his closest staff members and the fact that he was underpaid (he would have made at least 4 times more in the private sector), Stratton’s days at the Bureau were also numbered. The Bureau’s strongest champion, the man who had shaped it since its founding and seen it grow to more than 60 times its original size, left his position to assume the presidency at MIT beginning on January 1, 1923.


Secretary Hoover called attention in his press release on Stratton’s resignation to the fact the Government salaries were not competitive enough to keep qualified scientific men in Government positions. Hoover also named Stratton to the Bureau’s Visiting Committee, which meant that his influence was still felt there after his departure. Stratton also continued to be available for consulting with his successor Dr. Burgess, and during his tenure at MIT, he oversaw a reorganization that in many ways resembled the organization of the Bureau.


After rather lengthy debate, George Burgess, chief of the metallurgy division, was named successor to Stratton. Like his predecessor, Burgess would champion the link between the scientific study of the Bureau and industry, but unlike Stratton, Burgess was less involved in the day-to-day functions of the Bureau across the spectrum. He delegated authority, in contrast to Stratton’s autocratic nature, but he was accessible to any who sought his guidance. Under Burgess, the Bureau’s growth slowed as he was content to continue with work begun under Stratton, but let the dust settle for a while before taking on too many new tasks.


Some of the most important work conducted during the 1920’s was the Bureau’s continued work on establishing constants for different substances. The Bureau was especially concerned with temperature tables for different materials and greatly improved the data available for things like boiling and freezing points. They also collaborated on a new International Practical Temperature Scale. During this time the Bureau also investigated, in far greater detail than anyone ever had before, the specific characteristics of chemical elements, both alone and in combination with other elements by using spectroscopic test methods.


The Bureau’s involvement in the field of atomic physics began with a guest researcher from the University of Minnesota who introduced the concept of spectral analysis of metal vapor atoms. What began as an unfunded research hobby of two researchers in the optics division became the Bureau’s atomic physics section in 1922. The majority of the Bureau, however, continued to be consumed with industrial research.


Following the war, the country experienced a period of depression with the slowing down of industry. At the time, Herbert Hoover, who strongly supported the Bureau’s work and saw its value in restoring the economy, was Secretary of Commerce. The war had produced a housing shortage so when it became apparent that new home construction would be instrumental to job creation and industry revival, Hoover tasked the Bureau with researching the standardization of building materials and reviewing building codes. Hoover also established within the Bureau a division of simplified practice, whose purpose was to eliminate waste in industry by encouraging more conservative use of materials and more streamlined practices.


Bureau publications during the course of this housing stimulus included “Recommended minimum requirements for small dwelling construction,” “How to own your home,” and primers on plumbing, zoning, building codes and city planning. Bureau investigations also concluded that it wasn’t really necessary to have the customary winter slow-down in construction. The housing construction program lasted 8 years, from 1921-1929 and averaged 750,000 homes annually, which dramatically exceeded the need at the program’s inception. With a surplus of homes available, the Bureau’s building division saw staffing cuts from 36 to 2 by the time the Great Depression was in full force in 1933.

Despite all of the war-related research conducted at the Bureau, security was relatively lax. There was always a guard on duty, but most projects were not classified and security clearances were not required for the staff. In fact, the atmosphere was so relaxed that one day President Wilson, his wife and Secretary Redfield made an unscheduled Sunday visit to the Bureau to see the all-metal airplane being tested and although the building where it was kept was locked, they found an open window and all three climbed through to have a look. Another anecdote illustrates the ability of the Bureau to have fun: “An avid reader of detective and mystery novels, the President one morning sent a messenger to the Bureau with an envelope bearing his seal. He had read the night before that such a letter could be opened and resealed without any sign of tampering. Could the Bureau do it too? A day later the President had his sealed letter back, apparently intact. Inside was a note and the lead disks from which the fraudulent seal replacing his seal had been made overnight.”


With the somewhat abrupt end to the war, the Secretary of Commerce expected the Bureau to cease some activities and reduce staff that had been added for wartime research, but the Bureau reply was that the expected no reduction in work or staff and anticipated an increase in requests from the military, who were now aware of the need for more modern weaponry and technology and aware that the midst of a war was not the time to be addressing such concerns. As Congress greatly reduced appropriated funds for military research to the Bureau, the continuation of some projects had to be funded instead by the Army, Navy, etc. or the Agency to be served by the research. A precedent was thus set for transferring research funds within the budgets of other departments to the Bureau who would be carrying out the research. In later years, it would prove easier to obtain funding in this manner than asking Congress for direct appropriations.


After the war, Congress did award a large increase to the Bureau’s budge for industrial research, as the war had proven the connection between science and industry that was sure to prevail into the future. Americans were also made aware that the most important developments in physics and chemistry were coming from Europe at the time and they needed more research funding in order to remain competitive. Just as the switch from prewar investigations to military concerns had happened rather seamlessly, each department having wartime applications, the postwar argument was that practically all of their military work had industrial value and should thus continue. There was also a postwar interest in continuing the research to produce domestically the materials, instruments and other items previously imported from Europe that fed into the ongoing work of the Bureau.


Without wartime funding, the Bureau once again faced a staffing problem caused by the fact that private industry saw the need for trained investigators and could offer better salaries than the Bureau could, and as a result lost over 78% of its appointed staff members within 7 months of the armistice. For most positions, the Bureau paid less than a living wage to its employees. Recent college graduates might receive a decent entrance salary at the Bureau, but with industry competing for them too, it was not enough to offset the exodus.


The answer at the time to the staffing problem was to convince industry to send researchers on their payroll to the Bureau to conduct the research necessary. These “research associates” would then make their work available to the public, rather than doing secret experiments for the company that employed them. Having begun in 1919, this method yielded 61 research associates paid by 36 organizations by 1925.


In the postwar atmosphere of the country, the Government was accused of being too big and too inefficient. Answering this charge, the Bureau undertook studies on the cost and efficiency of the Federal Government itself. The resulting studies argued that, given the climate, more Government was actually in the public’s best interest to combat problems such as profiteering and inflation. According to the reports, the public needed to be better educated regarding Government spending. Almost 70% of federal income was used for paying interest on the national debt (incurred mostly through past wars) and only 3.2% was used to actually run the Government. The inefficiencies identified in the Bureau report, were the result of insufficient spending on salaries, meaning that Government posts did not attract or retain qualified personnel.

Pressure Transducers: Useful on the Farm


Typically used to convert liquids or gases to electrical signals, pressure transducers come in a variety of styles, for a number uses. Due to their unique functionality, pressure transducers are utilized in multiple industries and fields, including ammonia applicators for farms.


Ammonia Applicators


Recent reports indicate that Raven Industries Applied Technology division has released a new ammonia pumping system for farmers in the Louisville, KY area. This new system is purported to have quicker nitrogen releasing capabilities than previous systems. The products development team claims it can pump 50-80 gallons per minute. Notable improvements to the system include improved stainless steel piping and pressure transducers. The pressure transducers alert the operator if “an over-pressure situation is developing.”
