The anti-interference techniques and the encapsulation technique are dis- cussed The developed intelligent transmitter can overcome the shortcoming of the common pressure. transmitters in performance T he temperature performance and measuring precision are also im-. proved. The presented system is simple in structure, powerful in functions and reliable in operation, so it can be applied widely.
