(2)20世紀50年代有了精度稍高的力平衡式差壓變送器，但反饋力小，結(jié)構復雜，可靠性、穩(wěn)定性和抗振性均較差。 </p> <p> (3)20世紀70年代中期，隨著新工藝、新材料、新技術的出現(xiàn)，尤其是電子技術的迅猛發(fā)展，出現(xiàn)體積小巧，結(jié)構簡單的位移式變送器。 </p> <p> (4)20世紀90年代科學技術迅猛發(fā)展，變送器測量精度提高而且逐漸向智能化發(fā)展，數(shù)字信號傳輸更有利于數(shù)據(jù)采集，出現(xiàn)了擴散硅壓阻式變送器、電容式變送器、差動電感式變送器和陶瓷電容式變送器等不同類型。 </p> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p>

<p> 4、測量氣體壓力時，取壓口應開在流程管道頂端，并且變送器也應安裝在流程管道上部，以便積累的液體容易注入流程管道中； </p> <p> 5、導壓管應安裝在溫度波動小的地方； </p> <p> 6、測量蒸汽或其它高溫介質(zhì)時，需接加緩沖管（盤管）等冷凝器，不應使變送器的工作溫度超過極限； </p> <p>
