At the same time Faroll Research was engaged with Professor K. Weissenberg in the development of a Rheogoniometer, an instrument used to measure the properties of fluids and other non-Newtonian materials. The partnership between Faroll Research and Weissenberg flourished in that the Rheogoniometer became the world wide standard during the 1950s and 60s in the measurement and determination of fluidic properties such as viscosity, elasticity and thixotropic properties of many compounds. It was during the development of the Rheogoniometer that the first displacement transducer was used, this initially being purchased from a company called Boulton Paul Wolverhampton and was an essential measurement feature within the instrument. In 1965 Faroll Research was sold with its product range, including the Rheogoniometer, to Sangamo Weston Limited and became known as Sangamo Weston Controls Limited. During the latter part of the1960s and into the 1970s Sangamo Weston continued to market and manufacture the Rheogoniometer and develop other instruments involved in various forms of physical measurement. It was during this period that Boulton Paul indicated they no longer wished to manufacture the displacement transducer and offered the product line to Sangamo Weston Controls Limited. After the acquisition of this new displacement transducer product line, Sangamo Weston Control developed it further to give a wider range for differing operational uses, and introduced a complementary set of signal conditioning electronics. In 1976 Sangamo Weston was acquired by Schlumberger and the Division in Bognor Regis became known as Sangamo Transducers. In 1979 Sangamo Transducers produced its first gauging transducer using a linear ball race which gave significant advantages in repeatability over the products available on the world market at the time. In the 1980s Sangamo Transducers continued to develop complementary products to the displacement transducer adding further models to the range, and at the same time extending the signal conditioning electronics to add computer system capability for the user. It was during this period the Rheogoniometer, originally developed by Dr. Weissenberg, began to decline in sales as newer techniques and technologies became available and in 1985 this product line was sold to another U.Kcompany. From this period in 1985 Sangamo Tranducers became known as Schlumberger Industries, Transducers Division, Bognor Regis. They concentrated solely on the manufacture of displacement transducers, gauging transducers and supporting electronics to the point that they became recognised as a world leader in this form of technology with products being sold throughout the western world. In November 1993, following a management buyout, the Transducer Division became part of the Solartron Group Ltd and became known as Solartron Metrology. Then in April 1994, the ROXBORO GROUP PLC bought Solartron Metrology and the other Solartron Group Ltd companies. In 2005, three of the Solartron group companies, including Solartron Metrology were acquired by AMETEK, a leading global manufacturer of electronic instruments.
