User Video Manual for FT3351
GENERAL
- FT3351 series digital differential pressure transmitter, multi-functional smart pressure transmitter, is designed for industrial pressure measurement applications, based on our years of rich industrial manufacturing experience, adopting modern advanced, mature, reliable capacitive sensor technology, also combined with advanced single-chip computer technology and sensor digital conversion technology.
- CPU adopts sixteen single chips, whose powerful features and high-speed computing power ensures the transmitter with good quality and performance. The software has digital signal processing technology making transmitter with excellent anti-interference ability and zero stability, with zero automatic stable tracking ability (ZSC) and automatic temperature compensation ability (TSC).
- Powerful interface features without hand held communicator are able to ensure good interaction. LCD indicator can display the digital pressure, temperature, current three kinds of physicals and 0-100% analog indication. In case of non-standard pressure source, parameter setting zero shift, range setting damping adjustment can be by press key button; and also re-calibration on the transmitter are greatly convenient for on-site calibration.
- Serial interface communication can be converted to 4-20mA DC current signal output by via specified converter module, also available through Hart protocol( RS485 module) to set and monitor remote transmission, directly connecting with master device, such as paperless recorder, controller, indicator etc. instrument, HMI, IPC, PC, Industrial Lan.
- FT3351 are used to measure differential pressure, gauge pressure, absolute pressure. parameters for gas, liquid, vapor, widely applied in petroleum, metallurgy, chemicals, power, light industry, mechanical and environmental protection fields.
- FT3351 are available in 2 categories, 0.075% Accuracy and 0.15% Accuracy which is shown as below.
