Abstract
A mass determination device includes a combination of an elastic element connected with a mass holder. The combination has a normalized temperature coefficient of frequency substantially equal to zero over a temperature range of intended use for the mass determination device, whereby mass determination accuracy of the device during temperature change in the range is enhanced. The elastic element has a first normalized temperature coefficient of frequency over the temperature range. A second normalized temperature coefficient of frequency over the temperature range attributable to the mass holder is determined. The first normalized temperature coefficient and the second normalized temperature coefficient are substantially counterbalanced over the temperature range, for example, through material selection and/or heat treatment of the elastic element and/or material or geometry variation of the mass holder.
