Abstract

The design and operation of a strain gage signal conditioning amplifier is described. The complete amplifier is based on the Analog Devices 2B30 module and features adjustable gain, bridge excitation voltage, bridge balance, d.c. offset and low-pass filtering. The ease of construction and low cost of this amplifier make it ideal for applications requiring a large number of signal channels.

摘要

本文描述了一种应变片信号调节放大器的设计与操作。完整的放大器基于模拟器件公司的2B30模块，具有增益可调、电桥激励电压可调、电桥平衡、直流偏移和低通滤波等功能。这种放大器易于构建且成本低廉，使其成为需要大量信号通道的应用的理想选择。
