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”檢定規程(JJG59-2007)要求新研發設計制造。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)，性能極其穩定。活塞的工作介質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、和低溫度線脹系數的硬質合金碳化鎢材料經過精心研磨制成，工作環境溫度寬，性能穩定 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，壓力波動極小，示值準確。3.?25MPa以上傳壓介質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測，活塞上下行程為±1.5mm，儀表顯示具有靈敏、醒目、準確等優點。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，可抵目前國產測量上限 6、60、100MPa 三臺壓力計使用。?7. ?加壓調節輕便省力，即使在100MPa壓力時也能輕松自如。
