A bridge circuit is a common arrangement in a variety of different measurement applications, but particularly in force and pressure transducers. The output of these sensor types is proportional to the excitation voltage applied, and is measured in millivolts. Signal conditioning and interfacing these sensors with a microcontroller or a data acquisition system requires a precision voltage source and a precision high gain amplifier stage. This board provides both in a convenient package. Gain is programmed with a single resistor. Excitation is jumper selectable from 1.27V to 10V.
This current voltage monitor is designed to be installed in-line in your AC or DC power circuits to give a continuous analog readings of both current and voltage.
