Description The 2200 System incorporates all the features necessary for precise conditioning of strain gage (strain gauge) and transducer inputs in the most severe operating environments. Standard features include switch-selectable constant voltage/constant current excitation; + 350V common-mode capability; automatic electronic bridge balance; wide frequency response; switch selectable 4-pole Bessel low-pass filter.

Features

• Plug-in amplifier design
• Constant-voltage or constant current bridge excitation
• Calibrated gain of 1 to 3300
• Automatic wide-range bridge balance
• Selectable ac or dc input coupling
• Fully guarded input amplifier
• Full-power bandpass of 100 Khz at all gains
• Built-in Bessel low-pass filter with selectable cut-off frequencies
• Dual simultaneously buffered outputs
• Bridge completion for 120- and 350-ohm quarter-, half- and full-bridge circuits
