How to scale non-linear transducers?

Hi

I have a load transducer which is non-linear through zero (i.e. its sensitivity is different for compression than it is for tension). If I scale it as a By two points calibration I get a very large offset at zero. If I scale it by function it linearizes my "curve" and the end points are inaccurate.

I use other software (MTS FlexTest) that features a Gain/Delta-K function which allows you to have separate sensitivities for tension and compression; Gain for the positive end and Delta-K for the negative end of the signal.

Thank you!

Hi Lemmy,

If you define the sensor into the sensor data base, you will have more scaling types on option:

Let me know if this method suits for your needs.

Best regards.
