Bridge conditioners are instruments that provide excitation and support for strain gages, Wheatstone bridges, load cells and sensors. They also include circuitry for signal conditioning, amplification, and processing. Bridge conditioners provide four-way galvanic isolation between their input, output, excitation, and power supply circuits. Electrical isolation breaks the galvanic path between the input and output signals. Physical wiring between the input and output is not required. Normally, the input is transferred to the output by converting it to an optical or magnetic signal that is reconstructed on the output. In this way, bridge conditioners prevent unwanted signals from traveling along the input line.
