Barksdale的CDPD1H和CDPD2H內(nèi)置隔膜差壓開關(guān)是壓力控制應(yīng)用的答案,這些應(yīng)用需要防篡改的外部調(diào)節(jié),以及需要水密NEMA 4外殼的環(huán)境。這些壓力開關(guān)在正壓和真空模式下均可提供單或雙控制設(shè)置,壓力可達150 psi。這些開關(guān)可以通過常開或通過3/4“ -14 NPT導(dǎo)管連接到自由引線的方式進行有線連接。所有型號均具有標定刻度盤,用于調(diào)節(jié)單位的設(shè)定點,可以根據(jù)要求在工廠進行設(shè)置。對于需要高度可靠,準確的應(yīng)用Barksdale的CDPD1H和CDPD2H內(nèi)置隔膜差壓開關(guān)采用耐用的包裝,是選擇。
Barksdale's CDPD1H and CDPD2H Housed Diaphragm Differential Pressure Switches are the answer for pressure control applications requiring tamper proof external adjustment and environments which require water-tight NEMA 4 housings. These pressure switches are available in single or dual control settings for both positive pressure and vacuum models, to 150 psi. The switches may be wired normally open or normally closed through a 3/4"-14 NPT conduit connection to free leads. All models feature calibrated dials for adjusting setpoints in units can be factory set upon request. For applications requiring a highly reliable, accurate switch in a durable package, Barksdale's CDPD1H and CDPD2H Housed Diaphragm Differential Pressure Switches are the ideal choice.
