Hello
we are working on a project for a machine for capsule filling with powder. The powder will be filled by weight. The fill amount will be 400 , 600 & 800 mg. The error margin which is acceptable is 5 - 10 mg, so my thinking is to go with a load cell of resolution of 0.001g and total capacity of 10 - 20g. I am totally new to load cells and weighing powder side. I have done some research and I am baffled about a few things.
1. which properties of a load cell should be considered more than others in my case ? (hysteresis, resolution etc)
2. We would prefer a response time which is quicker (in milliseconds)
There are some load cells available cheaply in the market, but then there are others which are extremely expensive. Furthermore, for instrumental amplifier & ADC I am inclined towards getting one-chip solution like Texas instruments' ADS1242, so its less hassle.
If anyone of you have worked with any such situations, I would be grateful if you can share your experience and suggestion for appropriate parts.
