If you get a data acquisition board for your computer, this would be fairly easy.

There are many ways this can be achieved, depending on what it is that your sensor is capable of. Some devices can simply be plugged into the serial port of a PC and you could then monitor this information directly from there or as erick37 says a data acquisition board would work well.

How is this device conected to computer?

If it is a port VB may handle this but others might just requie driver making first and VC / DDK is a tool for that, can't do drivers whit VB.

Or is this just a electronic component or somekind of a modulle?
There are some multimeters in midle price serie witch got a serial port, this is possible way to translate value to computer and then convert it to weight.

The answer is, yes it is possible. It is done all the time for things other than the height of a person. The first thing you need to consider is the cost. On input would be very expensive. Check out for some small low cost equipment that could get the signal into the PC. There are some options to communicating to these devices. Some can use be used with VB. Let me know if you need more information.

As I suggested in my Rejected Answer, Go to

On the frame at the left are several categories you need to explore.
PLC Hardware
PC-based Control Products
Software Products
Operator Interfaces
Sensors & Encoders
Connection System

There are a lot of pictures to show you what these things look like. This sight contains pricing information to give you an idea of the cost. This is the lowest cost in the industry. You can order the stuff you need right there.
