The signal conditioner's main task is to convert the picked-up signal into a higher-level electric one. The signal from the sensor that is generated might need to be converted to be usable and to suit the different instruments it is connected to. Any standard process signal can be achieved by converting any sensor signal.
Besides needing to cover the measurement's frequency range, the analog filter of a signal conditioner can remove portions of the signal outside the range of interest.
For example, in-vehicle measurements of sound often have very strong low-frequency content below 20 Hz. A 20 Hz high-pass filter will attenuate the signal below the audio range which may improve the measurement system's noise floor at mid to high frequencies.
In addition to adjustable filters, signal conditioning offers gain control and other benefits:
Minimum and Maximum Gain: When using data acquisition system with adjustable input signal ranges, the noise floor of the complete measurement system (from transducer through conditioning to data acquisition) can be improved by adding gain in the conditioner.
Uni (Fine) Gain Adjustment: The sensitivity of a transducer in engineering units or volts typically varies significantly between individual transducers. Compensating for the individual sensitivities using fine gain control in the conditioner removes this error.
Transducer Electronic Data Sheet (TEDS): Significant measurement errors can be automatically avoided when the fine gain adjustment of the conditioner is read from the transducer's built-in TEDS support.
Multi-unit Rack: Assembling a rack for mounting is a convenient way of organising laboratory- based measurement systems where all the conditioning and data acquisition are combined. For most signal conditioners, you can order an optional 19-inch rack and/or a multi-unit frame, with which a single or more conditioner can be mounted together.
Signal Amplification:Increasing the signal (signal amplification) is a two-way process that is needed for digitalization or processing. The signal amplification can be carried out by either increasing the resolution of the input signal or by increasing the signal to noise ratio.
