• Trigger Pulse : generated internally
or externally
• Range measuring : 10~30 per
second is recommended
• Normal use : 10 per second is
recommended
• Ultrasonic burst signal from
Trigger Pulse
• The vibration and amplified
waveform according to
transmitting and receiving of
ultrasonic signal.
• Masking signal(Internal) to remove
the first received internal crosstalk
signal.
• Amplified signals only for the
reflected(received) signals
• Converting received signal to
digital form (signal)
• Time pulse proportional to the
distance of wave that reflected
first(proximal object)
• Preset limitation of distance
window(Preset range).
• Filtering the signal in which only
entered window limit
• Sample / Hold; converting the
approach signal to continuous
signal.
