Marsh Bellofram是一家專業(yè)生產(chǎn)的電氣轉換器、調壓閥、壓力表、橡膠膜片等氣動產(chǎn)品的美國公司，Marsh Bellofram所生產(chǎn)的產(chǎn)品的精度是世界上其他廠家無法相媲美。

   T-1000 961-112-000轉換器是一個電/氣轉換裝置――將模擬電信號轉換為按比例輸出的氣壓信號,進氣壓力范圍從1.27Bar到7Bar ，模擬電信號可以是mA電流信號，也可以是01VDC0EP/的電壓信號. 由于在設計上采用了氣動流量放大器,使的此產(chǎn)品的流量可達12 SCFM （20.16m3/hr）。允許的進氣壓力范圍從小的需求輸出壓力加0.21Bar 到大7Bar.

961-112-000電氣轉換器系列：

內置流量放大器,可作反向控制,氣耗量低,任意角度安裝,供壓范圍廣,低壓控制靈敏度高,外置調零及調幅裝置，使用方便,線路內有熱敏電阻提供溫度補償
