title: An inexpensive strain gage amplifier and signal conditioner for biological applications.
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.
