一、用途???? XY系列寬量程活塞式壓力計(jì)是我廠按照國家新“活塞式壓力計(jì)”檢定規(guī)程(JJG59-2007)要求新研發(fā)設(shè)計(jì)制造。由于活塞式壓力計(jì)的關(guān)鍵部件使用了高硬度和低溫度線膨脹系數(shù)的碳化鎢材料,?從而提高了活塞的耐磨性 ,因此受壓力后形變極小(可忽略不計(jì))，性能極其穩(wěn)定?；钊墓ぷ鹘橘|(zhì)采用了癸二酸二異辛酯，從而使壓力計(jì)具有極高的靈敏度。???? 由于采用了新材料、新技術(shù)、新工藝，所以新的活塞式壓力計(jì)的各項(xiàng)技術(shù)指標(biāo)有了很大提高。從而廣泛用來檢定數(shù)字壓力計(jì)、精密壓力表、壓力變送器、壓力傳感器等壓力儀器儀表。

二、性能特點(diǎn)：

1.?活塞和活塞缸均采用高強(qiáng)度、高硬度、和低溫度線脹系數(shù)的硬質(zhì)合金碳化鎢材料經(jīng)過精心研磨制成，工作環(huán)境溫度寬，性能穩(wěn)定 20±5℃。2.?負(fù)荷重心低，砝碼通過掛籃直接加在活塞上，活塞運(yùn)轉(zhuǎn)平穩(wěn)，壓力波動(dòng)極小，示值準(zhǔn)確。3.?25MPa以上傳壓介質(zhì)采用粘度很小的癸二酸二異辛酯，從而保證壓力計(jì)有極高的靈敏度。4.?壓力計(jì)所用砝碼全部采用無磁不銹鋼材料制做。5.?活塞工作位置用位移傳感器監(jiān)測，活塞上下行程為±1.5mm，儀表顯示具有靈敏、醒目、準(zhǔn)確等優(yōu)點(diǎn)。6.?量程寬，在下限1MPa時(shí)，基本誤差為±0.02%或±0.05%?，一臺XY1000型壓力計(jì)，可抵目前國產(chǎn)測量上限 6、60、100MPa 三臺壓力計(jì)使用。?7. ?加壓調(diào)節(jié)輕便省力，即使在100MPa壓力時(shí)也能輕松自如。
