From our first media-isolated pressure transducer to today’s complete line of microprocessor-conditioned piezoresistive level and pressure transmitters, gauges, and loggers, Keller has been advancing the state of the art in pressure measurement for over 40 years. We are Keller America, a wholly-owned subsidiary of Keller AG Druckmesstechnik, responsible for Keller product sales and support for all of North America. Our modern facility houses our experienced sales, engineering, and technical staff, as well as a complete production department where several level and pressure transmitters are built to your specification, with a standard delivery of 3 business days, or less.
