一、用途???? XY系列寬量程活塞式壓力計是我廠按照國家新“活塞式壓力計”檢定規(guī)程(JJG59-2007)要求新研發(fā)設計制造。由于活塞式壓力計的關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)，性能極其穩(wěn)定。活塞的工作介質(zhì)采用了癸二酸二異辛酯，從而使壓力計具有極高的靈敏度。???? 由于采用了新材料、新技術、新工藝，所以新的活塞式壓力計的各項技術指標有了很大提高。從而廣泛用來檢定數(shù)字壓力計、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：

1.?活塞和活塞缸均采用高強度、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.?負荷重心低，砝碼通過掛籃直接加在活塞上，活塞運轉平穩(wěn)，壓力波動極小，示值準確。3.?25MPa以上傳壓介質(zhì)采用粘度很小的癸二酸二異辛酯，從而保證壓力計有極高的靈敏度。4.?壓力計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、準確等優(yōu)點。6.?量程寬，在下限1MPa時，基本誤差為±0.02%或±0.05%?，一臺XY1000型壓力計，可抵目前國產(chǎn)測量上限 6、60、100MPa 三臺壓力計使用。?7. ?加壓調(diào)節(jié)輕便省力，即使在100MPa壓力時也能輕松自如。
