在試驗機選購中，我們經常會針對液壓機跟電子試驗機有個選擇對比，  以更好的選擇適合自己的機器，那么下面公司就針對液壓機跟電子材料試驗機做一個對比分析：
液壓材料試驗機，采(cai)(cai)用(yong)(yong)高壓(ya)(ya)液壓(ya)(ya)源為動(dong)力源。采(cai)(cai)用(yong)(yong)手動(dong)閥(fa)、伺服閥(fa)或(huo)(huo)比例(li)閥(fa)作為控制(zhi)元件進(jin)行(xing)控制(zhi)。普通液壓(ya)(ya)試驗機只(zhi)能(neng)進(jin)行(xing)人工手動(dong)實現加(jia)載，屬于開環控制(zhi)系統，受價格因素(su)的影響，測力傳感(gan)(gan)器一般(ban)采(cai)(cai)用(yong)(yong)液壓(ya)(ya)壓(ya)(ya)力傳感(gan)(gan)器。而電液伺服類(lei)材料試驗機則是采(cai)(cai)用(yong)(yong)伺服閥(fa)或(huo)(huo)比例(li)閥(fa)作為控制(zhi)元件進(jin)行(xing)控制(zhi)，國內有些廠家亦已經采(cai)(cai)用(yong)(yong)高精度負荷傳感(gan)(gan)器來進(jin)行(xing)測力。 

電子材料試驗機，不用油源。所以更清潔，使(shi)用維護更方便，它的試(shi)(shi)(shi)驗(yan)速(su)度范圍可進行(xing)調(diao)整，試(shi)(shi)(shi)驗(yan)速(su)度可達(da)0.001mm/min-1000mm/min，速(su)比可達(da)100萬(wan)倍之多，試(shi)(shi)(shi)驗(yan)行(xing)程可按(an)需要而定，更靈活。測力精度高，有些(xie)甚至(zhi)能達(da)到0.2%.體積小，重量輕，空間大，方便加配相應裝置來做各項材料力學試(shi)(shi)(shi)驗(yan)。真正(zheng)做到了一機多用。

液壓(ya)試(shi)(shi)驗(yan)(yan)(yan)機(ji)，受(shou)油源流量的(de)限(xian)制(zhi)(zhi)，他的(de)試(shi)(shi)驗(yan)(yan)(yan)速度(du)較低。手動液壓(ya)試(shi)(shi)驗(yan)(yan)(yan)機(ji)，操作較為簡易，價格便宜，但控制(zhi)(zhi)精(jing)度(du)較低。電液伺服試(shi)(shi)驗(yan)(yan)(yan)機(ji)，則性(xing)能與電子試(shi)(shi)驗(yan)(yan)(yan)機(ji)相(xiang)比，除速度(du)低外，控制(zhi)(zhi)精(jing)度(du)不(bu)會差，采(cai)用負荷(he)傳感器的(de)微機(ji)控制(zhi)(zhi)電液伺服試(shi)(shi)驗(yan)(yan)(yan)機(ji)，力值精(jing)度(du)也可(ke)以達到(dao)0.5%左右(you)。且在做(zuo)大(da)噸位的(de)材料力學試(shi)(shi)驗(yan)(yan)(yan)時，更(geng)更(geng)可(ke)靠，更(geng)穩定，性(xing)價比更(geng)高(gao)。

液(ye)(ye)壓材(cai)(cai)料(liao)(liao)試(shi)(shi)(shi)(shi)驗(yan)(yan)(yan)機(ji)主要用于金屬，非金屬材(cai)(cai)料(liao)(liao)和零件、部(bu)件、構件的拉伸，壓縮，彎(wan)曲等(deng)力學性能試(shi)(shi)(shi)(shi)驗(yan)(yan)(yan)。液(ye)(ye)壓試(shi)(shi)(shi)(shi)驗(yan)(yan)(yan)機(ji)是工(gong)、礦(kuang)企業、建(jian)筑建(jian)材(cai)(cai)、質(zhi)檢中心、水(shui)利水(shui)電(dian)、橋梁(liang)工(gong)程(cheng)、科研院所、大專院校力學試(shi)(shi)(shi)(shi)驗(yan)(yan)(yan)室的理想的試(shi)(shi)(shi)(shi)驗(yan)(yan)(yan)設備。手動控制的液(ye)(ye)壓試(shi)(shi)(shi)(shi)驗(yan)(yan)(yan)機(ji)，價格便(bian)宜，適合(he)工(gong)礦(kuang)企業的成(cheng)品檢驗(yan)(yan)(yan)、單一材(cai)(cai)料(liao)(liao)指標測試(shi)(shi)(shi)(shi)。而電(dian)液(ye)(ye)伺服材(cai)(cai)料(liao)(liao)試(shi)(shi)(shi)(shi)驗(yan)(yan)(yan)機(ji)，則適合(he)要求較(jiao)高的鋼鐵，建(jian)材(cai)(cai)檢測類(lei)的試(shi)(shi)(shi)(shi)驗(yan)(yan)(yan)室。湘杰儀(yi)器30T以上的電(dian)液(ye)(ye)伺服材(cai)(cai)料(liao)(liao)試(shi)(shi)(shi)(shi)驗(yan)(yan)(yan)機(ji)相比電(dian)子試(shi)(shi)(shi)(shi)驗(yan)(yan)(yan)機(ji)，更有價格優(you)勢

電(dian)子材料(liao)試(shi)(shi)(shi)驗(yan)機(ji)，廣泛應用(yong)于(yu)(yu)各種(zhong)金屬、非金屬、復(fu)合材料(liao)、醫藥、食品、木材、銅材、鋁(lv)材、塑料(liao)型材、電(dian)線(xian)電(dian)纜、紙張、薄膜、橡(xiang)膠、紡織、航空航天等行業進行拉伸性能指標(biao)(biao)的測試(shi)(shi)(shi)，同時(shi)可根據(ju)用(yong)戶提供的國內、標(biao)(biao)準定(ding)做(zuo)各種(zhong)試(shi)(shi)(shi)驗(yan)數據(ju)處(chu)理(li)軟件和試(shi)(shi)(shi)驗(yan)輔具(ju)。數字(zi)顯示電(dian)子試(shi)(shi)(shi)驗(yan)機(ji)適(shi)合于(yu)(yu)只求力值抗拉強(qiang)度抗壓強(qiang)度等相關數據(ju)的用(yong)戶。如(ru)需求取(qu)較為(wei)復(fu)雜參數，微機(ji)控制電(dian)子試(shi)(shi)(shi)驗(yan)機(ji)是(shi)您更(geng)好(hao)的選(xuan)擇(ze)。公司(si)  詳(xiang)細資料(liao)供參閱
