摘要本文介紹了利用凸臺圓膜片與測力傳感器組合而研制成的DPR 型應(yīng)變式差壓傳感器和應(yīng)變式差壓變送器。實踐證明，在中、高差壓范圍內(nèi)，該儀表對于雙向限位保護(hù)，消除彈性梁振蕩，提高應(yīng)變式差壓傳感器的精度及耐腐蝕、耐高溫等都是非常有效的。

Abstract The DPR strain type d/ p transducer and strain type transmitter developed by combining convex round diaphragm and force sensing transducer are introduced. In practical application the instrument is effective within medium and high differential pressure range for providing two directional limit protection，eliminating oscillation of elastic beam，enhancing accuracy and capability of anti-corrosion and high temperature proof.
