  • Comparison Between Sound Intensity Probes and Acoustic Cameras
    between the two microphones, it is possible to calculate both the sound pressure and particle velocity between the two microphones. These two parameters are then multiplied together to calculate the sound intensity. Sound Intensity, therefore, has direction. A sound intensity probe measures
  • Ultrasonic Sensors, The Silent Laborers
    are based on the delay time measurement. As has. been mentioned in the introduction, the "measurement representation" thereby is the. propagation velocity of the sound in the air, which is 330 m/s under normal conditions. The sensors utilized for these functions are however somewhat more precise
  • An Advanced Steering Wheel Sensor
    resistive element with a nominal 10 kresistance. The 5:1 ratio gear train was designed to eliminate the mechanical noise commonly generated by the parting lines on the gear tooth profile on plastic molded gear trains. Additionally, the shape and size of the sensor housing acts as a sound box that both
  • Delay Time Measurement with Ultrasonic Sensors
    Many industrial ultrasonic sensors are based on the delay time measurement. As has been mentioned in the introduction, the "measurement representation" thereby is the propagation velocity of the sound in the air, which is 330 m/s under normal conditions. The sensors utilized for these functions
  • Criteria for the Selection of the Proper Distance Sensor Technology
    with a resolution. of 5 m. The main characteristics of the sensors are: Suitable for different materials;. Suitable for small, quickly moved parts;. High resolution;. High linearity;. Short response time. Ultrasonic sensors. These sensors use the transmission from ultra sound to measure distances instead
  • Integrated Sensor and Controller
    rates can be. overcome by sound system architectural design and clever. programming, but the expertise and resource investment can be. significant. The servo sensor solution relies on a simple standard. high speed serial interface with a familiar communications. protocol. The approach of providing
  • TN 19: Piezoelectric Materials for Vibration Sensors - The Technical Advantages of Piezoceramics Versus Quartz
    , 1993, issue of Sound and Vibration Magazine, page 22.
  • Unraveling the Complexities of Level Detection (.pdf)
    : 763-553-7300 · Application Support: 1-800-544-7769 · Fax: 763-553-0708 · www.turck.com. ULTRASONIC. Ultrasonic sensors emit an ultrasonic pulse that refl ects back from any object entering the sonic cone. Because sound has a constant velocity at a given temperature and humidity,. the time taken
