What texts should I be checking out for instrumentation?
You might need to be a little more specific. Do you mean Electronic instumentation and at what level?
If you are thinking of doing a course on instrumentation, the specified text for the course would always be a good advance purchase.
You could also approach the teacher of the course and ask if there was any text or web site that might be useful to study before the course began.
Instrumentation always involves a detailed application of electronic theory, so some study in that area might be good if you feel you need it.
You could start here: http://en.wikipedia.org/wiki/Instrumentation" [Broken]
When you measure parameters, you need sensors: http://zone.ni.com/devzone/cda/tut/p/id/4045"
Well I would like to make sensors for measuring data in physics.
First, you need to work out what sort of data you want to measure.
You don't normally make sensors, because you have to buy most of them.
You can make some of them though. It might be as simple as putting two pieces of metal on a tank to see if it is full of water, or not, by checking for conductivity between them.
There are lots of different ways of measuring data to bring it into a computer, for example.
What level of electronics study have you done? What country are you in?
Courses I've taken: Digital and analog circuits(Hambley Txt)
That should give you some good background.
Have you used thermisters and light dependent resistors in your courses?
What would you like to measure?
