Whether in tanks or silos, universal level and distance measurement of liquids, bulk material or individual objects using ultrasound is reliable and accurate. But there is a catch. Even without direct contact with the medium, aggressive vapors and fumes can severely affect the function and life of a sensor. Our full-metal ultrasonic sensor aims to make this problem a thing of the past. From the diaphragm to the connector, the sensor is completely enclosed in high-grade 316L stainless steel, making it resistant to external influences and giving it extended service life.
