Yes, thanks. It is really informative. I am researching so that I can fabricate my own as it is too expensive to buy one. At least, I haven't found one cheap enough
alloy car rim. magnets. eddy currents. permanent magnets require a load cell, a pivot, and some way of varying the gap or flux strength. electromagnets need a variable power supply and can be calibrated so excitation voltage gives a direct reading... no load cells.
I recall a transmission test stand for Allison transmission, I worked on years ago. We had shear pins that would break before the flange .... made it easier to replace. Thanks for sharing ! Good stuff.
water has a high thermal capacity, higher than oil. water when its in contact with a surface limits the maximum temperature to 100C... it has to boil and evaporate for the temperature to exceed that. oil starts burning and stinks. and catches on fire. and makes a mess when theres a leak.
@@davesstillhere Wrong answer. I better go tell the company I work for that has been making air dynamoneters for the last 25 years that they don't work.

Me too. The load cell and instrumentation are what I expect to give me the most trouble, not being a computer guy.

Steve is the best! Great info.

Do you have am email I have some questions about a stuska xs-111 brake?
Why water instead of a 10w oil?

Why not just use air instead of water? Basically the same principle but you don't have to deal with water/plumbing issues.
Air compresses, water doesn't. Air wouldn't provide a load.

Really? I never heard of such a thing. Could you post a link to an article? I'd like to read up on it
Driveshaft through the roof! When your dyno throws parts, talk to Steve....
