First, if you never have designed any electronics yourelf, a differential (instrumentation) amplfifier is not a project for beginners. You should have at least some basic knowledge about operational amplifiers and their application.
Second, there are off-the-shelf devices which will probably fit your application, like this one:

Yes, I think that would be the best,
I don't quite know how much I would have to amplify it yet.
Do you know of an amplifier with a knob that allows you to change the gain?

The gain of the device mentioned in the first link can be set via wire jumpers but there are only three steps available.
The device of the second link is USB controlled and the gain can be set up to 1000x (probably from 1x onwards) via the driver software.
With bridge type sensors usually the output voltage is proportional to the excitation voltage (mV/V) for full range output. Of course you have to find out yourself under which conditions (mechanical load, travel, other physical conditons) you may get the full output range.

Hello All,
Greetings for the day.
I need help on NI-STS. I am from RF background and I am new to this domain.
Can anyone help me what exactly is this internal block diagram of 5530 and its modules.
One task i recieved is the RF signal recieved from 5530 need to come through amplifier that is the output signal of 5530 should be an amplified signal.
I need to control it from code.
Kindly help me in understanding these topics.
Thanks and regards
