Product Description

Overview for Ultrasonic Sensing

Ultrasonic sensing is the measurement of the time between an ultrasonic signal being sent and received. The interval between these two signals is typically referred to as time-of-flight (ToF) and depends on the distance the ultrasonic wave travels until it is reflected due to an impedance change and the speed of the ultrasonic wave. The basic equation time = distance / speed can be used to measure fluid level, fluid identification/concentration, flow, or proximity.

Benefits of Ultrasonic Sensing

  • Ultra-low power consumption (~2 µA) for battery-operated equipment
  • Non-intrusive sensor and lack of contact with corrosives enables simple design and maintenance
  • Flexible use in all types of tank materials and sizes

Highlights of TI's Ultrasonic Sensing technology

  • Only solution on the market with automotive-qualified analog front end
  • Design resources simplify adoption of ultrasonic-based solutions, minimize prototyping, and enable faster time to market
