System 6000
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
