Other Parts Discussed in Thread: TDC1000
At present, we mainly encounter the following problems, but also trouble engineers to give answers:
We are mainly used to measure the concentration of liquid, a sensor single transmission and single receipt.
1. test as shown in the oscilloscope, there is an echo signal, but change the ultrasonic wave propagation distance, the time difference does not change
2. Time difference has been maintained at about 40μm, but unstable, there are fluctuations.
3. Feel that the received signal is also not normal
I would like to ask what is the reason for this? How to solve?
