SUMMARY

Several washing machine solutions were examined. The

MPX10/12 solution can be expensive in terms of additional

support circuitry and the added time and labor involved during

the calibration procedure. The MPX2010 is good alternative

for high volume manufacturing because is already calibrated.

With this solution, however, the system amplifier design must

be chosen and designed carefully in order to minimize the sys-

tem error. This is a consideration when deciding to implement

a high accuracy solution with the MPX2010 because the cost

of the system will go up.

The MPXV4006G solution is geared towards high volume

manufacturing because trimming, compensation and amplifi-

cation is already on board. Besides the system simplicity and

using less component, the resolution and overall accuracy of

this solution is better than the MPX2010 solution. In some

cases, less components can actually improve the reliability

and manufacturability the system.
