耐震壓力表的使用需要注意

發布日期:2022-10-09 點擊率:72

1.耐震壓力表使用環境溫度為-40~70℃,相對濕度不大于80%,如偏離正常使用溫度20±5℃時,須計入溫度附加誤差。 

2.耐震壓力表必須垂直安裝,力求與測定點保持同一水平,如相差過高計入液柱所引起的附加誤差,測量氣體時可不必考慮。安裝時將表殼后部防爆口阻塞,以免影響防爆性能。 

3.儀表正常使用的測量范圍:在靜壓下不超過測量上限的3/4,在波動下不應超過測量上限的2/3。在上述兩種壓力情況下大壓力表測量都不應低于下限的1/3,測量真空時真空部分全部使用。 

4.使用時如遇到儀表指針失靈或內部機件松動、不能正常工作等故障時應進行檢修,或聯系生產廠家維修。 

5.耐震壓力表應避免震動和碰撞,以免損壞。 

6.訂貨時請注明:儀表型號及名稱;儀表的測量范圍;儀表的精度等級偏離正包裝要求和其它。 

7.根據用戶使用要求進行特殊設計。
