While ultrasonic and radar level sensors can measure your level to give specific feedback to how much of product is in a tank. A variety of sensors are available for point level detection of solids. Increased material resistance for maximum availability even under extreme operating conditions—this is offered by UBC series and UCC series ultrasonic sensors. After wave hits the target, the waves are reflected and the detector collects the signal. Ultrasonic sensors are used to measure distance or travel time using ultrasonic waves. These transducers send the electrical signals to the object and once the signal strikes the object then it reverts to the transducer. Compact, right-angle ultrasonic sensors with built-in temperature compensation. How Ultrasonic Sensors Work. Sensing range < 300 mm. Ultrasonic sensor can be active (or) passive, where passive ones pay attention for particular sounds like metal on metal, glass breaking. The gapless design ensures that cleaning agents run off completely, and that bacterial growth is prevented. During the usage of multiple ultrasonic sensors in a single system, there can be interference (cross talk) from the other sensors. The highest level of product and process reliability is ensured during the filling and packaging process of groceries and drugs, making it the ideal sensor type for use in chemistry and process engineering due to the use of high-resistance materials.
