1.  4-wire resistive:  Are applicable when cost is the paramount consideration but suffer from two issues.   

  • Susceptibility to drift caused by temperature and humidity variations.
  • Failure caused by top layer damage.

2.  5-Wire resistive:  Are used when failure from top layer damage or excessive use is unacceptable.  Click for detail.
