Gemco Liquid Level Sensors







Gemco started as a custom electrical panel fabricator, but soon developed several standard control products, including our renowned, industry standard, rotary cam limit switches. In the 1970’s Gemco expanded into resolver based electronics and 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 application. The Gemco brand remains on many of the Sensor Technology products today, including our DeviceNet sensors and Allen-Bradley PLC Bus Card Products. B/W Controls began with liquid level controls for water and wastewater applications.

Products included conductance probes, float sensors and level control packages. In the 1980’s magnetostrictive level sensors and leak detection products were introduced. These products are well recognized for EPA compliance in underground storage tank monitoring as highly accurate solutions. Today, new products, based on advancements in the Gemco and B/W Controls 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, we can show you how to improve productivity and process performance, leading to lower cost and improved competitiveness for your business.
