The conversion values for the MLT003/D Grip Force Transducer vary according to the excitation voltage being applied to it. When the transducer is plugged into the Differential input on a PowerLab, which supplies ± 5 Volts excitation, the Units Conversion value will be 11.9 mV per 100 Newtons. When it is plugged into an FE221, FE224, or FE228 Bridge Amplifier, which supply ± 8 Volts of excitation, the Units Conversion value will be 19.0 mV per 100 Newtons.
