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.
Bridge conditioners receive three types of inputs: signal inputs, sensor inputs, and inputs from special devices. Signal inputs include DC voltage, DC current, AC voltage, and AC current. They also include frequency and charge, signals that often require filtering and amplification. In terms of sensors, current loop converters receive inputs from accelerometers, thermocouples, thermistors, and resistance temperature detectors (RTDs). They also receive inputs from strain gauges, many of which use a Wheatstone bridge, and from both linear and rotary variable differential transformers (LVDTs and RVDTs). Inputs from special devices include not only signals from encoders, but also signal per cycle counts from counters or tachometers. Timers, clocks, relays, and switches can also provided special inputs to bridge conditioners.
