What Is A Dead Zone? |
|
Answer» A dead zone refers to the area directly in front of the transducer face where the sensor cannot reliably make MEASUREMENTS. This is due to a phenomenon CALLED ringing. Ringing is the continued vibration of the transducer after the excitation pulse. The ENERGY must dissipate before the transducer can listen for a return echo. Make sure to LOCATE your target OUTSIDE of the specified dead zone of your ultrasonic sensor.
