產(chǎn)品詳情
VACUUM SWITCH壓力表VL-650-R3產(chǎn)品對(duì)電源的使用有恒流源和恒壓源,兩者都是通常壓力傳感器采用的兩種激勵(lì)。兩種激勵(lì)方法是有區(qū)別的,其作用不同。恒流源激勵(lì)有利于熱靈敏度漂移的補(bǔ)償作用。因?yàn)闃虮垭娮杵鞯臏囟认禂?shù)為正,而靈敏度溫度系數(shù)為負(fù)。恒流激勵(lì)時(shí)的輸出信號(hào)電壓的溫度系數(shù)是兩者的代數(shù)和。而恒壓激勵(lì)不能直接提供靈敏度溫度補(bǔ)償效果。但用恒壓源激勵(lì)時(shí)可在橋外串接熱敏電阻或二極管以補(bǔ)償熱靈敏度漂移。用橫流激勵(lì)時(shí),這種靈敏度補(bǔ)償方法便不起作用??梢?,恒壓源和恒流源激勵(lì)互相之間不能隨意互換。

VACUUM SWITCH壓力表VL-650-R3產(chǎn)品可以通過它們所能測(cè)量的壓強(qiáng)范圍,工作溫度以及壓強(qiáng)類型而進(jìn)行分類;其中最重要的是壓強(qiáng)類型。若依壓強(qiáng)類型分類的方式中,壓力傳感器可以分為以下五類:
絕對(duì)壓力傳感器:這種壓力傳感器量測(cè)流體真正的壓強(qiáng),也就是相對(duì)于真空壓強(qiáng)下的壓強(qiáng)。海平面上的絕對(duì)大氣壓力是101.325kPa(14.7 PSI)。
表壓力傳感器(gauge pressure sensor):這種壓力傳感器可以量測(cè)某一特定的位置下,相對(duì)大氣壓的壓強(qiáng),胎壓計(jì)就是一個(gè)例子,當(dāng)胎壓計(jì)顯示讀數(shù)為0PSI,表示輪胎內(nèi)部的壓力等于大氣壓力,為14.7PSI。
真空壓力傳感器:這種壓力傳感器用來量測(cè)小于一大氣壓的壓強(qiáng),工業(yè)界有些真空壓力傳感器的讀值是相對(duì)于一大氣壓(讀值為負(fù)值),而有些是以其絕對(duì)壓力為準(zhǔn)。
壓差計(jì):此儀器用來量測(cè)二個(gè)壓強(qiáng)之間的壓強(qiáng)差,例如量測(cè)濾油器兩端的壓力差,壓差計(jì)也用來量測(cè)流量或量測(cè)壓力容器內(nèi)的液面高度。
密封壓力傳感器:此儀器和表壓力傳感器類似,不過此儀器會(huì)經(jīng)過特別的校正,其量測(cè)的壓強(qiáng)是相對(duì)海平面的壓強(qiáng)。
