Thanks for all your advice. I plan to connect the force transducer to a Bruel & Kjaer Mini-shaker type 4810. The shaker will generate vibrations that will be picked up by a bone-conductive microphone and these vibrations are very small. The greatest force I need to measure is about 0.3 Newton and this is because the shaker will not vibrate around its default position, but instead around a slight offset.
Greg Locock:
The most sensitive Bruel & Kjaer force transducer has a sensitivity of 110 mV/N, which may be a little on the low side (we will try it, but I doubt the sensitivity is enough).
Greg Locock:
You are correct that 0.3 N is not a particularly small force. However, this corresponds to a constant force (the DC-component sent into the shaker). The vibration force (corresponding to the AC-component sent into the shaker), on the other hand, will be very small. I would like to find a force transducer which has a big enough dynamic range to measure both of these two components accurately.
