 The Endevco Bridge Transducer Signal Conditioner Model
4430A can be used with any of the bridge-type transducers,
such as pressure gauges, strain gauge potentiometers and
ISOTRON® type accelerometers.
The Model 4430A Ultra Low Noise Programmable Bridge Signal
Conditioner provides: Amplifier gain (1 to 1,000 or 1
to 10,000 for 4430A-1); a low pass filter (selectable
from 10 Hz to 30 kHz); isolated, programmable voltage
excitation (.100 to 15.000 Vdc in 5 mV steps); programmable
current (0.5 mA to 100 mA in 0.1 mA steps); bridge balancing,
amplifier zeroing (to within less than 1 mV RTO); and
calibration modes. The unit can perform both automatic
and manual amplifier zeroing and bridge balancing.
All functions can be manually programmed from the front
panel by means of EDIT keys, two MENU SELECT keys, and
LED bar graph (MENU and LEVEL indicator), and an ENTER
key. All setups are verified on the five-character alpha
numeric LCD display.
Optional IEEE-488 programmability is provided by the Endevco
Model 4960A Rack, which can house up to ten Model 4430A
units. The optional power pack (P/N 4961) provides stand-alone,
single-channel, front panel operation of the 4430A.
Features:
• Manual or IEEE 488 computer controlled
• 100 KHz bandwidth
• 300 V common mode rejection
• Automatic and manual bridge balance and amplifier zero
• 0.1% gain accuracy
