For more than forty years, we have been developing and manufacturing high-precision, extremely reliable measuring systems and sensors for the toughest requirements at our Gettorf site. Our spectrum ranges from flow sensors and air flow monitors to compressed air consumption meters and inductive or capacitive proximity switches to infrared detectors as well as opto and ultrasonic sensors. We also develop level monitors based on all common measuring principles, photoelectric sensors for industrial applications and metal detectors for harsh use in quarries and building materials production.
