So, I’m still working on the next W7212 post. But meanwhile, I ran into a cool resource I wanted to share; specifically, the HP Application Notes web site.
Years ago, when I first started to transition from pneumatic controls to DDC, I found an application bulleten called Practical Temperature Measurement. Turns out it was published by HP and I learned a lot from it including the fundamental stuff that I know about thermocouples, RTDs, lead lenght compensation, and thermistors.
I came across the application bulletin the other day and got to wondering if you could get a .pdf copy of it. Turns out that you can at the HP Application Notes web site I link to above. Its bulletin 290, so you have to scroll down a bit to find it.
As you scroll down, you may notice something else that catches your eye. The site seems to be full of information.
Nothing on the W7212 though, so I will return to that in the next post.
