Gateway Supply was started in Sidney, Ohio U.S.A in May of 1972, as a stocking distributor of plumbing products and accessories. Robert Kramer purchased part of the company in 1983, and the balance in 1992. Using his past distribution experience as a guide, Mr. Kramer converted Gateway into an industrial distributor of pipe, valves, fittings, hose, compressed air products, and related products which now include over 60 different manufacturers and product lines. Sales for Gateway now exceed five times what they were in 1983, and regular customers now include Honda of America, Compair Leroi, Norcold, Alcoa, and Metokote corporations. Additionally, Gateway sells to the Defense Logistics Agency and received several awards for excellence during Operation Desert Storm.

As a solutions company, we provide more than just sensor products. Decades of application engineering provides the perspective and experience to quickly prototype, build and deliver your selection of quality level, flow and pressure sensor variations. Research and development teams simulate actual application environments, perform environmental testing and evaluate electrical loads. Experience has taught us which technologies and product characteristics provide effective solutions to customers' problems. There's a good chance we've already dealt with the design criteria you're working on and will probably have a product solution available right off the shelf. That saves you both time and money! And if your application calls for a more customized solution, Gems will meet your requirements by modifying an existing product or designing a completely new sensor. At Gems, "off–the–shelf" doesn't mean end–of–story!

Jefferson Sudamericana S.A. has developed a wide range of float and displacer magnetic level switches, which are placed in the interior or the exterior of the container to be controlled. The magnetic system eliminates the technical problems of other devices, such as blocked stuffing boxes, worn-out diaphgms, corroded electrodes, and besides, it offers the advantage of containing all the mechanical and electrical elements on the same hydrometric column. This arrangement simplifies the time and cost of installation. Its high-quality mercury switches made of special "Pirex" glass, allow to protect its operation from any factor affecting the electric contacts, such as suspended dust, humidity, etc., as well as preventing any possible "contact stickings" due to excess of current or short-circuits.
