Abstract :This paper present s the compensation principle and the low power consumption designing method of a two2wire diffusion silicon differential pressure t ransmitter. A single2chip microcont roller is used to calculate the actual differential pressure value , with high accuracy , by sampling pressure out2 put and temperature of the differential pressure sensor and searching the initialized data. The t ransmit2 ter is easy to operate , having excellent performances.
Key Words :Differential pressure t ransmitter , Digital compensation ,Low power consumption design
