Hi all,

I'd like to get information about precision measurement system which can detect
resistance change due to piezolever deflection ( resistance change :10 ~ 300
mili ohm in 2 Kohm resistance piezolevern which purchased from Microscopes ).
This type of small resistance change can be measured by wheatstone bridge type
measurement system, but most of them cannot measure such a small resistance
change in a big resistance piezolever.

Please, let me know if you have or know what kinds of systems are commercially
available and where to buy those kinds of systems.

Thank you.
