Chapter 1: Introduction

Features

The FBDA is a signal conditioning module that allows you to
measure voltages produced by full-bridge sensors using a data
acquisition module. This module can condition signals from Strain

Gauges, Load Cells, Pressure Sensors, and other Full-Bridge
Transducer Sensors. A number of different gain settings are

available on the FBDA to accommodate a wide variety of voltage
ranges. The FBDA also provides an adjustable excitation voltage for
the full-bridge circuitry. The sensor connections are made using
terminal blocks, and the A/D connections are made through a DB-25
connector. B&B Electronics’ SDAXX, and ADIO12 data acquisition
modules are pin compatible with the FBDA. This allows you to
simply plug one of the data acquisition modules mentioned above
into the FBDA, and the A/D connections are complete. The SPDA
data acquisition modules can also be used with the FBDA.
