Embedded supervisory control and output reporting for the oscillating ultrasonic temperature sensors

Ultrasonic temperature sensors can potentially outperform conven-tional sensors because they are capable of very fast sensing across the complete ultrasound pathway, whilst conventional sensors only sense temperature at a single point and have substantial thermal inertia. We report recent develop-ments in electronic instrumentation for oscillating ultrasonic temperature sen-sors with the aim of achieving high accuracy and low scatter at a low cost.
