3B18

GENERAL DESCRIPTION

both voltage and current outputs.

The 3B18 is a wideband (20kHz) single-channel signal

conditioning module which interfaces, amplifies, and filters

signals from balanced 4-arm full-bridge strain-gage bridges

with a resistance from 100Ω to 10 kΩ, providing simultaneous

precision voltage and current outputs. The module provides two

user-selectable (via front-panel switches) bridge excitation

voltages: +10 V for bridges with a load impedance down to

300W or +3.33V for 120W bridges or others below 300W.

Module bandwidth is also user-selectable between 20 kHz and

100 Hz, with user-supplied filter capacitors installed in the

optional AC1310 ranging card. The 3B18 protects the computer

side from damage due to field-side over-voltage faults up to

130V rms. In addition, the current output withstands 130V rms

without damage and interfaces user equipment through screw

terminals located on the 3B Series backplane. The 3B18 is a

plug-in, mix-and-match, hot-swappable module which is easily

field calibrated via front-panel zero and span adjustments for

3B Series Custom-Ranging Program – Externally-

programmable Model 3B18-00, enables the user to configure a

special input range by using the optional plug-on AC1310

ranging card, which houses user-supplied resistors to determine

zero and span. To facilitate selecting resistors, a Windows

program, 3B-CUSTOM, calculates resistor values based on the

user-desired input/output ranges.

A chopper-stabilized low-drift (+1uV/^oC) input amplifier

assures long-term stability. For user convenience, the zero and

span can be factory configured to meet custom range needs

(Model 3B18-CUSTOM) or can be externally programmed

(Model 3B18-00) via user supplied resistors inserted in the

optional AC1310 plug-on ranging card.
