一、概述 SITRANS 7MF4233 壓力變送器能測(cè)量液體和氣體的壓力,并輸出對(duì)應(yīng)的4-20mA模擬信號(hào)和數(shù)字信號(hào)。可通過(guò)控制鍵,HART 通訊, PROFIBUSPA 或基金會(huì)現(xiàn)場(chǎng)總路接口進(jìn)行參數(shù)設(shè)定。
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.
