34970A怎么获取压力数据

大家好，我是新来的，很高兴见到你们所有人:)我有一个关于用我的34970A用20通道多路复用器和工作台链接数据记录器来监控压力的问题。
我有一个组合压力头Penningvac PTR90（它是Pirani + penning）通过FCC电缆连接到turbolab80泵系统（非常经典）。
涡轮增压器在前面板上有一个RS232，但我没有线索可以发送输出信号。
然后，我想将FCC电缆直接连接到数据采集单元，记录信号（电压我想......）并通过工作台链路数据记录器将它们转换为压力。
问题是：是否可以使用我的数据采集单元监控压力？
我怎么能用我手工制作的组件进行良好的压力测量？
谢谢:)编辑：Seebeck于2014年6月25日上午7:02

  Hi all, I am new here so nice to meet you all :)

i have a question regarding the possibility to monitor a pressure with my 34970A with 20 channels multiplexer and bench link data logger.  

I have a combi pressure head Penningvac PTR90 (it's a Pirani + penning) connected to a turbolab80 pumping system via FCC cable (very classic). The turbolab have a RS232 in the front panel, but i have no clues it could send an output  a signal. Then, i thought to connect the FCC cable directly to the data acquisition unit, record the signals (voltage i suppose...) and convert them to pressure via bench link data logger.

The question is: is it possible to monitor a pressure with my data acquisition unit? How could i perform a good pressure measurement with the components i have by hand?

Thank you :)
