About Signal Conditioners

Signal conditioning products provide amplification, filtering, converting, and other processes required to make sensor outputs suitable for reading by computer boards. Signal conditioning products are used primarily for data acquisition, in which sensor signals must be normalized and filtered to levels suitable for analog-to-digital conversion so they can be read by computerized devices. Signal conditioning type, form factor, device specifications, signal inputs, sensor inputs, specialized inputs, transducers and excitation, outputs and user interface are important parameters to consider when searching for signal conditioning products Other specifications to consider when selecting signal conditioning products include application, software, memory and storage, network specifications, filter specifications, amplifier specifications, and environmental parameters.

Products & Services Related to Signal 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).
