CF3351 Digital • Smart Pressure / Differential Pressure Transmitter

The core component uses a 16-bit single-chip microcomputer. Its powerful functions and high-speed computing capabilities ensure the excellent quality of the transmitter.

CF series digital intelligent pressure differential pressure transmitter is a multifunctional digital intelligent instrument developed by our company based on many years of industry manufacturing experience. Based on the world's advanced mature and reliable capacitive sensor technology, it combines advanced single chip Computer technology and sensor digital conversion technology are carefully designed.
The core component uses a 16-bit single-chip microcomputer. Its powerful functions and high-speed computing capabilities ensure the excellent quality of the transmitter. The entire design framework focuses on reliability, stability, high precision and intelligence to meet the increasing requirements of industrial sites. To this end, digital signal processing technology is applied to the software, which has excellent anti-interference ability and zero point stability, and has zero point automatic stability tracking capability (ZSC) and automatic temperature compensation capability (TSC).
Powerful interface functions ensure good interactivity without hands. The digital LCD display head can display three physical quantities of pressure, temperature, and current, and 0100%  instructions.The key operation can conveniently complete the basic parameters such as zero shift, range setting, and damping setting without a standard pressure source. Settings, and the transmitter can be recalibrated, which greatly facilitates field debugging
The S-POR serial communication port communicates directly with the computer through a special transfer module. The host computer interface can complete more functions than key operations. Connect to a dedicated R485 module to achieve remote transmission of digital signals, or to build an S485 industrial LAN
Integrated design for signal conversion, signal acquisition and processing and current output control makes the structure more compact and reliable
