Ametek-Patriot Sensors
Our roots go back to the 1930's with the Gemco Electric Company and the B/W Controls Company as core businesses. These companies were merged while both were part of McGraw-Edison in 1981. McGraw-Edison was acquired by Cooper Industries, which later sold the controls business, including Gemco and B/W Controls, to MagneTek.
Gemco started as a custom electrical panel fabricator, but soon developed several standard control products, including our renowned and still industry standard rotary cam limit switches. In the 1970's Gemco expanded into resolver based electronic programmable limit switches, where we set many industry standards including unique high speed output performance. In the 1980's, Gemco brand magnetostrictive LDT's were added. We have continued to develop our product lines around unique solutions in difficult applications. The Gemco brand is still carried on many of the Patriot products today.
B/W Controls began with liquid level controls for water and waste water applicatioins. Products included conductance probes, float sensors and level control packages. In the 1980's B/W brand magnetostrictive level sensors and leak detection products were introduced. These products are well recognized for EPA compliance in underground storage tank leak monitoring as highly accurate solutions.
MagneTek is a trademark of MagneTek, Inc. McGraw-Edison and Cooper Industries are trademarks of Cooper Industries, Inc.
Today, new products, based on advancements in the Gemco and B/W core technologies, provide even greater value creation for our customers and are a cornerstone for our future strategy. As a leader in Linear and Rotary Position Sensing, and Level Gauging, Patriot is the SOLUTIONS DEPOT for adding value in the most demanding industries and applications.
