Examples of Keller Products in Use
Dear colleagues, we invite you to familiarize yourself with the applications of Keller products. Over its more than 35-year history, Keller sensors and transducers have found wide application in various fields worldwide. Thanks to extensive experience and a high level of production automation, Keller has achieved significant success: on one hand, we have a range of high-precision pressure transducers with a basic error of 0.01% FS, and on the other, general industrial pressure transducers that, with high accuracy and stability parameters, have a cost comparable to much less accurate analogs from other manufacturers.
