Intelligent differential pressure sensor differential pressure level sensor
Description of Intelligent differential pressure sensor differential pressure level sensor
Intelligent differential pressure sensor differential pressure level transmitter will cause changing of capacitance value, analog signal convert to digital signal via AD and then being transfered to microprocessor, processed by microprocessor then convertted to 4～20mA analog electricity signal via DA.
The core components use 16 single-chip, its powerful features and high-speed computing power ensure the quality of the transmitter. The entire design framework focuses on reliability, stability, accuracy and intelligence to meet the ever-increasing demands of industrial field applications. To this end, the software uses the digital signal processing technology, it has excellent anti-jamming capability and zero stability, and has zero automatic stability tracking ability (ZSC) and temperature automatic compensation capability (TSC).
