Marsh Bellofram是一家专业生产的电气转换器、调压阀、压力表、橡胶膜片等气动产品的美国公司，Marsh Bellofram所生产的产品的精度是世界上其他厂家无法相媲美。

   T-1000 961-112-000转换器是一个电/气转换装置――将模拟电信号转换为按比例输出的气压信号,进气压力范围从1.27Bar到7Bar ，模拟电信号可以是mA电流信号，也可以是01VDC0EP/的电压信号. 由于在设计上采用了气动流量放大器,使的此产品的流量可达12 SCFM （20.16m3/hr）。允许的进气压力范围从小的需求输出压力加0.21Bar 到大7Bar.

961-112-000电气转换器系列：

内置流量放大器,可作反向控制,气耗量低,任意角度安装,供压范围广,低压控制灵敏度高,外置调零及调幅装置，使用方便,线路内有热敏电阻提供温度补偿
