壓力表類型的確定
壓力表類型的選用必須本著“滿足工藝生產(chǎn)要求”的原則進行確定，下面小編具體來介紹如何確定壓力表的類型。
1.被測介質(zhì)的性質(zhì)，如介質(zhì)的溫度高低、是否帶黏度、是否帶腐蝕性、帶臟污程度及是否易燃易爆。如果帶有其中任何一項特殊性質(zhì)，都需要選用帶有對應(yīng)功能的壓力表。
2.自控要求，用戶是否需要遠傳、自動記錄或報警。
3.特殊要求，應(yīng)用現(xiàn)場是否對壓力表有著特殊的要求，如現(xiàn)場濕度、現(xiàn)場是否帶大型電機設(shè)備、是否有振動源存在等等。
因此根據(jù)實際工藝要求正確的選用壓力表是保證壓力表可以正常工作及安全生產(chǎn)的重要前提。
