Model 6010 Strain Gage Card
Features :
  • Complete strain gage signal conditioner with 16-bit analog-to-digital converter.
     
  • Programmable digital filter
     
  • Programmable excitation supply per channel. The supply is settable to 0, 0.5, 1, 2, 5, and 10V. Up to 50 mA of excitation current is available on each channel. Remote sense is provided for full-bridge transducers.
     
  • Programmable gain to complement the excitation steps of 1, 2, 5, and 10V. Full-scale input range will be ±16 383 . An excitation setting of 0.5V will use the 1V gain range, but with one-half the resolution. Gain settings are independent per channel.
     
  • Internal bridge completion resistors: 120 , 350 , and 1000 dummy resistors (jumper selectable); 1000 internal half bridge
     
  • Programmable coarse balance range of ±16 300 (4096 steps)
     
  • Fixed low-pass anti-aliasing filter (six-pole)
     
  • Two programmable shunt calibration circuits
     
  • Input connections to user's strain gage via nine-pin D-sub connector
