Many innovations for driving comfort and safety are based on new sensor systems, for which Preh develops such novel solutions.
Position sensors are developed and manufactured by Preh using proven thick-film technology as well as non-contact Hall designs.
An important component of robust, low-wear potentiometric sensors is the Preh-patented paste system for thick-film production. This is based on a hard conducting pigment that is embedded in a lacquer system. The thick films are manufactured fully automatically under clean-room conditions.
For non-contact measurement, Preh has a command of various technologies. Hall applications have been employed in control systems for many years, before being used in today’s throttle flap applications. Preh has also developed a novel capacitive measuring method for the level of liquids.
