簡(jiǎn)單介紹：

電壓和電流輸出模塊量表、真空及復(fù)合壓力模塊通用型可沖洗外殼厚隔膜結(jié)構(gòu)保證高耐壓性

詳情介紹：

12ET系列壓力傳感器

本安型傳感器，OEM壓力傳感器具有獨(dú)特的耐壓和穩(wěn)定特性----真空至6000 psi (400 bar)

特性...

電壓和電流輸出模塊
量表、真空及復(fù)合壓力模塊
通用型可沖洗外殼
厚隔膜結(jié)構(gòu)保證高耐壓性

概述/設(shè)計(jì)原理:

本安型12ET系列壓力傳感器采用CVD和ASIC設(shè)計(jì)技術(shù)，以及獨(dú)特的厚隔膜使其穩(wěn)定堅(jiān)固。厚隔膜使傳感器承受泵震動(dòng)，電磁閥等引起絕大多數(shù)壓力尖峰。16ET系列也屬于本安型，具有滿足苛刻的工業(yè)要求全焊接不銹鋼后端，擴(kuò)寬了客戶外殼材料的選項(xiàng)范圍。模塊化設(shè)計(jì)可使用戶尤其是OEM客戶專門定制其中的配件、電纜等。ASIC和CVD技術(shù)也使Gerns公司提供所有壓力范圍的幾乎所有輸出.

Applications:

非公路用車（OHV）
天然氣設(shè)備
半導(dǎo)體加工
電站
制冷
機(jī)器人技術(shù)
暖通空調(diào)（HVAC）
