The company was founded in 1921 under the name British Sangamo as the UK subsidiary of the Sangamo Electric Co. of Springfield, Illinois, USA and manufactured, initially, kilowatt hour meters, later expanded its activities to include industrial time switches.
In 1936 Sangamo acquired the British Weston Electrical Instrument Co. of Surbiton, Surrey. This company was the United Kingdom subsidiary of the Weston Electrical Instrument Corporation, of Newark, New Jersey, USA, a company founded by Dr. Weston (a pioneer in the field of electrical measurements), and recognised as one of the worlds leading manufacturers of electrical measuring and associated equipment.
The two companies were combined to form Sangamo Weston, which designed and manufactured a wide range of electrical measuring and control equipment. Sangamo Weston Became associated with products for the aviation industry and as a result, Entire devoted its resources during the 1939-45 was, to the production of measuring instruments, indicators and associated ancillary equipment for use on aircraft.
After World War 2 resources were put back into the original product lines But They continued to design and manufacture aircraft measuring instruments, indicators, measuring systems and associated equipment for customers all over the world.
In 1950 our Port Glasgow factory and offices were opened in Renfrewshire, Scotland from where we continue to operate today. As can be seen in this Glasgow Herald article, we have proudly employed the majority of our staff from the local area for over 60 years. The view from our factory, 425ft above sea level, looking out over the Clyde to Loch Lomond and the Trossachs to the North, Glasgow to the East and the Clyde Esuary, Dunoon and Bute to the West is surely among the most picturesque in Scotland if not the world!
In later years the current directors bought out the company from Actaris and it once more became Sangamo Limited. While we, in Port Glasgow, are the succesor of the time switch division the metering division of Sangamo, which ran from Felixtowe, Suffolk, still exists today under the name Itron Metering Solutions.
Interestingly, Port Glasgow was originally a small village known as Newark. This ties nicely in with Weston Electrical Instrumentation Corporation being based in Newark, New Jersey – way over on the other side of the Atlantic.
