Temperature Compensation Cost-effective temperature compensation achieved using standard ohmic resistors combination with built temperature sensor. With fixed values temperature compensation error output signal (span plus offset) typical less then achieved range (see Figure better temperature compensation possible measurement temperature coefficients sensor. this case optimized described Chapter 3.10 (see Data Book). Alternatively ASIC used calibration compensation.
