SITRANS 7MF4033 壓力變送器能測量液體和氣體的壓力，并輸出對應的4-20mA模擬信號和數字信號。可通過控制鍵，HART 通訊， PROFIBUSPA 或基金會現場總路接口進行參數設定。
     測量變量： 腐蝕性和非腐蝕性氣體、蒸汽和液體的表壓壓力。
     · 量程(連續(xù)可調) DS III HART 系列： 0.01 ... 400 bar g
     · DS III PA 系列7MF4034 (PROFIBUS PA)：  1 ... 400 bar g
     · DS III FF 系列7MF4035 (基金會現場總線)： 1 ... 400 bar g

The SITRANS P DS III series includes digital pressure transmitters for measuring gauge pressure, absolute pressure, differential pressure, flow and level. Even the standard devices offer comprehensive diagnostics and simulation functions with high reliability. The suitability for use in SIL2 circuits has been certified by external test institutes. With Profibus transmitters, the new PROFISAFE technology guarantees uniform safety from the control system down to the transmitter.
