Many innovations for driving comfort and safety are based on new sensor systems. Preh develops such novel solutions.
Position sensors are developed and manufactured by Preh using the proven thick-film technology as well as non-contact design, for example with Hall.
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 throttle flap applications nowadays. Preh has also developed a novel capacitive measuring method for the level of liquids.
