Need help finding an electronic component


If you're wanting a load cell that uses a more industrial interface, you're probably not going to find anything inexpensive. But there are two industrial standards I can think of that you could use if once you figure out how to interface with a load cell.

The first is a constant current output of 4mA to 20mA. It's a common industrial standard that just about any robot or PLC can understand. It's also less prone to noise than most analog solutions, but you would have to tell whatever is reading to translate the current range to whatever your weight range is.

The other very common (and in this case possibly preferred) would be Modbus over TCP. Just about everything uses this interface nowaday. Plus, it's even an open standard that's relatively well documented, but making your very own modbus device would be an entire project all on it's own.

Both of those would only have as much latency as you design them to have.
