Welcome to the form. Yes, I am very interested. Are you able to post more information or is there a web site you can refer me to?
If you prefer you can also send me a U2U message.

SLIP Indicator and LOAD Indicator, for Induction motor is what i manufacture, I woudl like to know if someone is interested in seeing how it works since it is .01% accurate and is nearly working in more than 20 locations
Always glad to hear about new products. It sounds like this one measures slip to estimate load. We have historical slip available by looking at our predictive maintenance vibration spectra. Also can be determined by handheld strobe.
We find it is useful to look for changes in equipment operation which may correlate to (explain) changes in equipment vibration. For example some pumps vibrate more at low flow and on these particular pumps that corresponds to lower slip.
Slip I guess forms a diverse indication which can compliment current indication.
Other than identifying change in loading pattern, slip might possibly indicate rotor bar problem. But such problems are more easily recognized with other technologies imho.
0.01% may represent accuracy in speed or slip (?) determination, but surely not load determination.
