簡(jiǎn)單介紹：

5 到 6000 psi (0.35到 414 bar) 長(zhǎng)壽命的耐磨盤設(shè)計(jì) 有DPDT型可選側(cè)裝DIN連接頂裝電氣連接

詳情介紹：

PS75 系列壓力開關(guān)
堅(jiān)固的圓柱型壓力開關(guān)

概述/設(shè)計(jì)原理:

Gems PS75系列具有全金屬表面以限制過載，在高壓波動(dòng)的環(huán)境下仍能出色的工作。內(nèi)部設(shè)計(jì)耐磨盤和減震環(huán)以延長(zhǎng)壽命。還采用活塞/隔膜設(shè)計(jì)，集活塞技術(shù)的耐高壓特性和隔膜技術(shù)的高靈敏度于一身。現(xiàn)場(chǎng)可調(diào)或工廠設(shè)定.

* In certain applications, deadband can be tailored and controlled to customer specifications. Consult factory for details.
** Operation of both switches in most cases will not be simultaneously but will occur within the specifications listed. Deadband figures already reflect the improvement from the -RD option which is automatically included in the -AA, -BB, and -CC circuits.
