Signal conditioners are designed for processing analog signal of transducers in order to meet the requirements of a data acquisition device so that the computer-based measurement systems can effectively and accurately recognize the signals.Signal conditioning may include amplification, filtering, converting, range matching, isolation and any other processes required to make sensor output suitable for processing for the next stage.Signal amplifier can bring up the millivolt output of a sensor where the signal resolution and signal-to-noise ratio have been increased for an analog-digital converter (ADC) to recognize and process.Signal conditioners normalize the sensor outputs and filter those signals to certain levels that can be read by computerized devices, e.g. Data Acquisition (DAQ) Systems.Compare to analog signals, digital signals can provide a high degree of immunity from electrical noise and support extended transmission distances and are easily connected to a computer. Therefore, digital USB sensor interface or Digital Conditioners are developed to enable analoginputs to be converted into a digital format such as RS232, RS485 or even Ethernet and with an Ethernet output, the input signal can be read across the entire network or internet based on the configuration setup.Lorenz Signal Conditioning product and system are ideal solutions for all process and testing applications, and USB interfaces are available to transfer digitizedanalog sensor signals to the PC and signals can be visualized by the Configuration and Evaluation Software VS2.
Strain gauge signal conditioner receives an electrical input from full Wheatstone strain gauge based transducers and provides signal amplification, filtering, linearization or more beforeit can be read accurately by an ADC on the DSP (Digital Signal Processer). It converts the low millivolt input into the selected DC voltage or current output signal which is linear to the input. Furthermore, signal conditioners are also used when a transducer requires excitation source to complete the measurement of a physical phenomena. The similar concept applies on LVDT signal conditioners except they receive input signals from full or half- bridge LVDT sensors.
