OK, to be honest, my brother is the electronics and computer guy, I am the power grid guy and the motor head. I am doing research to build a brake dynamometer. This will require multiple temp sensors, tachometers, and a few other basic instrumentation. We want to use mostly IR temp sensing for simplicity of test vehicle setup. We would also like to use IR sensing for tach pickups as well.
I guess our first objective is to determine how to make these IR critters? They seem a little to costly commercially since we will need around 5 temps sensors, and 4 tach sensors. Temp range will be 50-250F, and 500-1300F, and the tachs will need good precision and 0-5000 rpms or ppm. So can anyone help with design of these little guys component wise?
We are also a machine shop so building the holder devices for potting and such should not be an issues. The next order here will be building the daq system but we will save that for another thread I guess.
