Signal Conditioner 101

In order to carry out this process, signal conditioning is a data acquisition process that is used by an instrument known as signal conditioner. This tool converts one type of electrical or mechanical signal into another (output signal). Input-signal. It is intended that this signal be amplified and converted into a readable and compatible form for data collection or machine monitoring. An accurate data acquisition and machine control measurements can be carried through by the signal conditioner. These devices can perform a number of additional functions. This might be a bit different from an Omron signal converter.

Signal Conditioning Functions

Amplifying

The next step is to amplify the signal and increase the signal for processing and digitalization. There are two ways to amplify the signal: by increasing the input signal resolution or the signal-to – noise ratio. Signal Conditioning uses a number of amplifiers that are optimised for use with DC signals to suit a variety of different purposes including instrument amplifiers with a high input impedance, a high common CMRR and a high gain. The isolation amplifier, which can isolate high DC levels from the equipment during the passage of little AC or differential signal, could also be an example of a signal conditioner for amplification.

Signal Conversion

A signal conditioner ‘s main function is to collect and convert the signal into a higher electrical signal level. Signal conversion is frequently used in industrial applications with a wide range of sensors. Due to the various sensors used, it may be necessary to convert the generated signals to be used for connected instruments. Every sensor signal can be converted to a standard process signal.

Linearization

Some signal conditioners can linearise if the sensors do not directly link the signal to the physical measurement. This means the software signal, which is often used for thermocouples, is being interpreted. This method is used to improve accuracy, as not all sensors are completely linear. The parameters for linearization are evaluated and specified by the sensor calibration protocol during the sensor calibration
