KELLER Pressure
A market leader in the production of isolated pressure transducers and transmitters. KELLER Pressure was established in 1974 by Hannes W. Keller, the inventor of the integrated silicon measuring cell. Today, his sons Tobias and Michael Keller run the business. The company is wholly family-owned and employs 450 staff. KELLER level sensors are used to measure static and dynamic levels of water in wells in a reliable and precise manner. Level measurement is of paramount importance, as it provides information on the behaviour of the well and pumping equipment. Suitable measurement and data analysis enable proactive identification of the need for preventive maintenance due to deterioration of the grooved well casing. For instance, they are used to measure the sea depth, monitor the water pressure at the bottom of dams, calculate flow quantities and regulate water levels.
