About Bridge Conditioners

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. 


Products & Services Related to Bridge Conditioners
Current Loop Converters
Current loop converters convert an analog or digital signal to a current loop output such as 4-20 mA or 0-20 mA.
Current-to-Voltage Converters
Current-to-voltage converters scale and convert current signal input to the desired output voltage range.
Data Acquisition Input Modules
Data acquisition input modules accept sensor and other signal output for data acquisition systems. They may include signal conditioning prior to the analog-to-digital conversion stage.
Data Acquisition Output Modules
Data acquisition output modules or cards transfer amplified, conditioned, or digitized signals.
LVDT and RVDT Signal Conditioners
Linear variable differential transformer (LVDT) and rotary variable differential transformer (RVDT) signal conditioners are devices that translate the linear or rotary movement of a ferromagnetic armature into an AC voltage that is proportional to the armature position.
Sensor Transmitters
Sensor transmitters are measurement or signal conditioning packages that provide a standard, calibrated output from a sensor or transducer in the form of a current loop output (e.g., 4-20 mA).
Voltage Converters and Voltage Inverters
Voltage converters and voltage inverters accept voltage input and provide a scaled voltage output. Conversion types include scaling up a low-level signal, voltage doubling, and inversion (converting a positive voltage to negative and vice versa).
