Sensor Precision FT-150 and FT-300

Hey,

How can I find the precision for your FT sensors. I have looked at the spec sheets but I can't find it.

Hi,

For our sensor, we mainly use the noise signal as a measure of the precision.
And here is why:

The signal noise is a random signal carrying no useful information created by various elements mainly electronics. Below that level, there is too much interference to have a good reading of the actual signal we are looking for. Therefore, any signal that goes below this level can’t be considered with a good precision. This is why the precision of a signal can be defined by this noise level.

The further your variation is from the noise, the more precise your reading will be.

If you have any more questions, feel free to let us know!

Signal noise is used instead of precision, it is the limiting factor when it comes to measuring and using the signals from your FT-Sensor. Signal noise is basically the signal movement around the "true" value. The noise we get in the sensor is quite similar to a white noise, see picture below. If you would have no reading ( 0 N in Z), with our signal noise over 1 sec (1000 ms) you would get something like this :
