2200 System Signal Conditioning Amplifier

Request Info

The 2200 Signal Conditioning System incorporates, as standard, all the features necessary for precise conditioning of strain gauge and transducer inputs in the most severe operating environments.
The 2210A Amplifiers plug in from the front of the ten-channel 2250A Rack Adapter or four-channel 2260A Portable Enclosure without removing the rear-panel input connections. A single-channel adapter is also available.

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 gauge 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.

Configuration
The 2200 Signal Conditioning Amplifier Modules can be used as stand-alone single-channel units or can be plugged into racks for multi-channel testing.
