Abstract: A piezoresistive pressure transmitter with lower resistance was designed using AD693 chip, which has the function of digital signal conditioning. The design of application circuit was given in detail. And the corresponding static test was done. Experiment results show that transmitter has good performance in the temperature range of 20 ℃~60 ℃, and has perfect time shift and stability better than 0.1%.
Key words: lower resistance; piezoresistive pressure transmitter; performance measurement; time drift
