"Seed Packets Counting
This XXX convergent-mode sensor produces a powerful infrared beam which registers one clean “count” signal from each seed packet – dark and light printed areas are sensed equally. The small convergent image produced by this sensor reliably responds to the short-duration spaces between adjacent packets."
...signal that counts one packet? also, why "clean"? (does it mean "neat" in this sense?)

English term (edited):
clean �count� signal

clearly-defined...
I think it means that the signal is quite distinct, unambiguous --- maybe this is what you meant by 'neat'?
It is a 'count' signal because it serves in counting the packets --- in other words, it is not merely detecting the presence or absence of a packet (though of course inevitably it works like that!), nor is it in any way interpreting the state of the packets. So it represents an intermediate level of criticality...

Of course, it means \"used for counting how many packets pass by\"

Note in reply to JCC\'s comment:
Whilst I totally agree that in normal electronic terms, we do of course talk about a \'noisy\' signal, from the context given in this question (and earlier ones), I feel sure this is referring to a \'clear-cut\' signal at the detection stage, rather than any qualitative reflection on the actual electrical state of the signal itself.

: Electrical signals can have lots of 'dirt' on them. Or, they could mean here that the packets are separted by some distance.

Thanks, JCC! They specifically state that there is a 'short-duration' space between packets...

Ken Cox
: Yep, here 'clean' is the opposite of 'noisy' or (more abstractly) 'ambiguous'.
