 		 #184477 - re re
Responding to: ???'s previous message

maybe i have not made myself clear.

You still did not.


You wrote You have already almost whole system ready - except weighing module. In any conditions cost of this system is far bigger than any weighing indicator on market. Simply buy and use.

If You want to study high precision analog technic - its other deal -
congratulations and good luck.
Same in case You plane to go into amplifier market.

If You want to launch 2 hoppers fast and reliable - buy new indicators and use them.

regards
