What I need to do is to measure a dynamic pressure which oscillates around an average pressure.
My average pressure is 90 BarG whilst the oscillations are less than 1% (PTP) about this average.
My problem is that the sensors I have are 0-100 BarG, with an accuracy of +/-0.15% of full scale (output is 0-10V FS)
The sensor covers the range, but the accuracy does not meet my needs and I don't think it is practical to buy anything with a better accuracy (if such a sensor exists).
Has anyone ever heard of a pressure sensor that gives its full scale output over a limited elevated range, say in my case 0-10V over 80 to 100 BarG, or is such athing wishfull thinking.
Sorry if this is the wrong place to put this post, but I wasn't sure on the best forum.
