HYDAC傳感器(qi)(qi)是一種被廣泛應用(yong)(yong)于各種工業自動化系(xi)統中(zhong)的傳感器(qi)(qi)，其被設計用(yong)(yong)來檢測、測量、監測和控制環(huan)境中(zhong)的物理(li)、化學和生物參數。本篇文章將會為您詳細介紹HYDAC傳感器(qi)(qi)的使用(yong)(yong)手(shou)冊，以(yi)及如何在實際應用(yong)(yong)中(zhong)正確地安裝、配置和維護這(zhe)些(xie)傳感器(qi)(qi)。

壓阻式壓力傳(chuan)感(gan)器具有精(jing)度高,靈(ling)敏度高,穩定性好(hao)、頻率響應范圍(wei)寬、易于(yu)小型化(hua),便于(yu)批量生產與使(shi)用方(fang)便等特點,是一種發展迅速(su)，應用

廣(guang)泛的新型(xing)傳(chuan)感(gan)器(qi)。但是由于半(ban)導(dao)體的溫(wen)度(du)特(te)性壓(ya)阻式壓(ya)力傳(chuan)感(gan)器(qi)會發生溫(wen)度(du)漂移(yi),在相(xiang)當程度(du)上限(xian)制了壓(ya)阻式壓(ya)力傳(chuan)感(gan)器(qi)的應用。壓(ya)阻
