and

> 0-70, 100, or 200 bar, and are linear for a 50kHz response with a 0.5 to
5V

like

> the conditioning module/fiber/sensor. I'd like to get a PCMCIA data
> acquisition card for some testing (basic pressures and temperatures, I
> figure an 8 channel 12 bit 100k would fit the bill). Are there any

> generic setups in the school control systems lab a few years ago.
