TNF-3051 intelligent pressure / differential pressure transmitter is my company draw on advanced foreign experience, the application of full isolation circuit technology developed and designed with full isolation HART communication protocol intelligent field measuring instruments.
Since the transmitter circuit technology with a full isolation design, the power supply box sensor signal isolated and greatly improve the overall stability and anti-jamming capability.
The transmitter has three basic function keys in addition to the conventional zero adjustment smart transmitter, span and zero pressure fine-tuning, but also on the display designed by F1, F2 and F3 three buttons used in combination with online passive migration (no need to add pressure to set the measurement range, zero and full bit amend pressure value), set the display unit quantities, linear, square root transformation, set the damping time and fixed current output function. The transmitter also has a parameter data backup and restoring functions. When the data is damaged, online restore corrupted data via three buttons, and you can instantly backup data modifications.
