Increasing Sensor Reliability through Ultrasonic Transducer Optimization For any desirable product, reliability is a key component. Reliability, combined with accuracy, performance, quality and cost are what enable a user to establish a product's overall value. These factors drive decisions, so determining what makes a product reliable and also understanding how the environment and reliability of a product are related is vital. This article outlines the reliability of ultrasonics utilized in chemical level sensing. It focuses more specifically on how a reliable transducer is key for a well-performing, long-lasting ultrasonic sensor. Ultrasonics can be selected and used much more effectively in a range of environments, including wastewater and turbulent water, or the chemicals employed with processing – even those once believed to be incompatible with the technology.
