Introduction
FPT74 product is piezo-resistive Smart pressure transmitter with HART Communication Protocol and zero and span adjustable. It uses high stable and reliable pressure sensor and special circuit board to produce transmitter, and performance is good and reliable.
FPT74 pressure transmitter is used for measure and control of petroleum, chemi-industry, electric power, hydrology and flow pressure measure, etc.
