I decided to cure the cement for 14 days and take the inductance reading after. I still haven&#39;t started the experiment coz I’m waiting for the approval of my needed materiaen-USTelligent Community 12https://community.element14.com/challenges-projects/design-challenges/inductive-sensing/b/blog/posts/steelquad-steel-quality-sensing-device-week-5-80198048Mon, 16 Jun 2014 12:40:29 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:7564fdcc-1d67-4d14-82f6-685b22f71c94Kilohercas1<p>I can&#39;t get my head around your idea. From my point of view, you will try to evaluate metal quality where you can assess it by means of measuring it&#39;s effect to inductive coil. <br />My question is how can you get any usefull information about metal properties based on permeability, if different compositions and other fact will alter greatly your measurement. In the&nbsp; over words, you will be measuring something that is function of many things, and you can&#39;t control or know about them. as example you will measure L(μ), but μ is function of many variables, so what you end up is L(μ(x,y,z,t,f)). Or maybe i just don&#39;t understand how you are going to achieve your goal</p><img src="https://community.element14.com/aggbug?PostID=17895&AppID=111&AppType=Weblog&ContentType=0" width="1" height="1">
