CF3351 Digital • Intelligent Pressure / Differential Pressure Transmitter

CF series intelligent digital pressure /  differential pressure transmitter is an intelligent digital instrument of multi  functions independently developed by the company through integrating our  many-year industrial manufacturing experience; it is elaborately designed by  combining with advanced single chip computer technology and sensor digital  conversion technology on the basis of capacitor sensor technology that is  internationally advanced, proven, and reliable.
 The instrument is cored with a 16-bit  single chip microcomputer, whose powerful functions and high speed computing  capability strongly guarantee the excellent quality of the transmitter. The  design, as a whole, is with a view to performance reliability, stability, high  precision and intelligentization, which fulfill the requirements of industrial sites  nowadays that get demanding day by day. Therefore, the software is applied with  digital signal processing technology which provides the instrument with  excellent performance of resisting disturbance and zero point stability as well  as zero point stability self tracing capability (ZSC) and temperature self compensation  (TSC) capability.
 Powerful interface function ensures good  interaction performance of the transmitter while no hand operation is needed  any more. Digital LCD display of the meter can display such three physical  measurements as pressure, temperature, and current values and simulation  indication from 0 ~ 100%. Through key operation, basic parameter settings such  as zero point deviation, range settings, damping settings etc can be completed  easily without standard pressure source provided; besides, the transmitter can  be recalibrated, all of which make instrument commissioning on site extremely  convenient.
 Via S-port serial communication port, it  directly communicates with computers through special switching module. Through  the interface of upper computer, further more functions can be completed than  through key operations. Digital signal transmitting can take place through  connecting the instrument with special RS 485 module or constructing RS 485 industrial  local area net (LAN).
 Integration design is adopted for the  instrument for signal conversion and acquiring, and processing and control of  current output, which makes the transmitter structure more compact and reliable.
