抗腐蝕的壓力變送器沒有液體的傳遞，壓力直接作用在陶瓷膜片的前表面，使膜片產(chǎn)生微小的形變，厚膜電阻印刷在陶瓷膜片的背面，連接成一個惠斯通電橋(閉橋)，由于壓敏電阻的壓阻效應(yīng)，使電橋產(chǎn)生一個與壓力成正比的高度線性、與激勵電壓也成正比的電壓信號，標(biāo)準(zhǔn)的信號根據(jù)壓力量程的不同標(biāo)定為2.0 / 3.0 / 3.3 mV/V等，可以和應(yīng)變式傳感器相兼容。通過激光標(biāo)定，傳感器具有很高的溫度穩(wěn)定性和時間穩(wěn)定性，傳感器自帶溫度補(bǔ)償0～70℃，并可以和絕大多數(shù)介質(zhì)直接接觸。 </p><p

T法適合速度比較低的場合，當(dāng)轉(zhuǎn)速較高時其準(zhǔn)確性較差；而M法其性能特點(diǎn)正好與T法相反，比較適合于高速場合，M/T法則是前兩種方法的結(jié)合，在整個速度范圍內(nèi)都有較好的準(zhǔn)確性，但對于低速，該方法需要較長的檢測時間才能保證結(jié)果的準(zhǔn)確性。三種方法的各項(xiàng)性能比較如表3.2所示：表3.2
