Temperature compensation of the pressure sensors as the solution of the optimalization task
Janusz Zelezik · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1995
The paper presents the general algorithm of the selection of the elements for the temperature error compensation of the pressure sensors: zero and sensitivity (range). It depends on the minimalization of the performance index that comes out of the purpose of the compensation (i.e. minimalization of the mean square error or maximum error in the range of the working temperature variation), while taking into consideration the limiting system. There is an exact and not linear sensor model used. The method may be used along with the constant resistor compensation as well as with the compensation by elements depending on temperature. The graphs show the results of the practically carried out compensation.
