Description
The 2200 Signal Conditioning System incorporates, as
standard, all the features necessary for precise
conditioning of strain gage and transducer inputs in
the most severe operating environments.

Features
- Plug-in amplifier design; amplifiers are
removable from the front panel without rear
access.
- Constant-voltage or constant-current
excitation; 0.5 to 15V or 0.5 to 30 mA;
selectable by single internal switch.
- Calibrated gain from 1 to 3300; adjustable
front-panel gain switch and calibrated
front-panel ten-turn potentiometer.
- Front-panel monitoring of:
+
10V output; excitation; automatic balance status;
and amplifier balance.
- Automatic wide-range bridge balance with
battery backup to retain balance in power-off
condition.
- Input coupling; selectable ac or dc by
internal jumpers.
- Fully guarded input amplifier;
+
350Vdc or peak ac common-mode operating voltage.
- Full-power bandwidth of 100 kHz at all gain
settings; slew rate of 6.3 V/microsec.
- Built-in four-pole Bessel low-pass filter
with cutoff frequencies of 1 Hz, 10 Hz, 100 Hz, 1
kHz and 10 kHz; front-panel frequency selection
switch.
- Two simultaneous buffered outputs;
+
10V and tape 1.0 Vrms; will drive up to 0.15
microfarad without instability.
- Stable, proprietary bridge completion module
for quarter- and half-bridge 120 and 350-ohm
strain gage and transducer circuits.
- 120-ohm dummy easily configured for 1000-ohm
completion.
- Built-in shunt calibration circuits; internal
user-selectable configurations to provide
two-point shunting of any bridge component or
two-point double shunt calibration of
transducers.
- Optically isolated shunt calibration relays
provided as standard; built-in power supply for
relay operation is provided in ten-channel rack
adapter and four-channel enclosure.
