Research on the Temperature Compensation of Smart Differential Pressure Transmitter

The real-time temperature compensation to the differential pressure signal of transmitter is researched in this paper to meet the requirement of high precision measurement. The curve fitting method and BP neural network method are presented mainly. The temperature-sensitivity coefficient before compensation is 6.6×10-3/ , after compensated by ℃ curve fitting method or BP neural network method is 7×10-5/ or 6.5×10 ℃ -5/ . ℃
