Sensor data acquisition and data processing

For example, if you were measuring a voltage signal smaller than a few millivolts, you might need to amplify it. If you had a signal contaminated with noise you could filter it. Proper signal conditioning is essential in getting an accurate measurement of your signal.

Sensor data acquisition and data processing

Different stimuli can be generated and the response can be analyzed in different ways.

Device Test Plan supports connection with external systems through serial communication. Up to 16 DDP viewers can be opened. General Functions Sensor Sensitivity The acquired data can be rescaled according to the sensor sensitivity configured by the user so that the displayed data are expressed in engineering unit corresponding to the physical quantity sensed by the sensors.

This is very different from a conventional oscilloscope whereby only voltage can be displayed. Graph Operation Zooming and Scrolling is supported in all graphs, allowing you to investigate the fine details of the data. This is very important when a large amount of data are displayed in one screen.

A cursor reader is provided in each graph to show the x and y readings of the actual measurement point. For Spectrum 3D Plot, the cursor reader supports the readout of x, y, t values of the actual measurement point.

Two markers are provided in each graph to get the x and y readings of the actual measurement points nearest in horizontal direction to the points of the mouse clicks. Five chart types are supported: Line, Scatter, Column, Bar, Step.

Line width and colors of the graph are configurable. Options are provided to either display all data points slow or only display one data points per vertical raster line fast. The data in any graph can be copied into the clipboard as text and later paste into other software such as Microsoft Excel for further analysis.

The image of the graph can be copied into the clipboard as Bitmap image and later paste into other software such as Microsoft Word. Reference Curves Up to five reference curves can be set for each channel in each graph.

The reference curve can be configured by either copying the current curve, or loading a properly formatted text file or a previously saved reference file from the hard disk.

A long wave file can be imported frame by frame either manually or automatically.

THE ULTRASONIC TRANSDUCER

Wave files with PCM format or properly formatted text file can be imported for analysis. The signal generated by the signal generator can be saved as a wave file or a text file for a given duration of up to seconds. Data Merging and Extraction Combining data from individual channels of different wave files, and extracting part of data from a wave file are supported.

Save and Load Panel Setting You can save your preferred instrument panel setting either as default or as a customized panel setting for later use. Software Customization Multi-Instrument provides the following user customizable features: Multi-Instrument can work as an ActiveX automation server so that an external program can access the data and functions that Multi-Instrument exposes.

You can integrate Multi-Instrument into your own software seamlessly via the ActiveX automation server interfaces exposed by Mutil-Instrument. Multi-Instrument Automation Server Interfaces. As all these devices conform to the same vtDAQ and vtDAO interface standard, you only need to write the interface codes in your program once and your program will support all these devices.

When used in conjunction with Multi-Instrument software, these VT DSOs convert any desktop, laptop, or tablet PC into a powerful oscilloscope, spectrum analyzer, multimeter, data logger, signal generator and so forth, all of which work simultaneously.

Compared with the first-generation VT DSOs and those USB oscilloscopes from other manufacturers, this new generation has the following major advantages: They are used to measure in real time the frequency response of an audio system within the confinement of the environment, taking into account the frequency response of the audio system itself as well as all the environmental effects such as resonance and constructive and destructive interference.

One can then adjust the equalizer to make an inversed frequency response such that the combined frequency response is flat or aligned to the preference of the audiences. Normally pink noise is used as the test tone and octave analysis is set in the spectrum analyzer.

It is able to perform all the functionality of a conventional RTA such as the measurements of frequency response and sound level, with finer resolution and higher accuracy thanks to the computing power of a modern computer.

In addition, it can measure various types of distortion and perform a comprehensive set of functionality that is usually not found in a conventional RTA.Electromagnetic Wire Rope Inspection System LMA-TEST (USB)™ Specification Sheets.

Data (ISSN ) is a peer-reviewed open access journal on data in science, with the aim of enhancing data transparency and reusability. The journal publishes in two sections: a section on the collection, treatment and analysis methods of data in science; a section publishing descriptions of scientific and scholarly datasets (one dataset per paper).

Signal Conditioning - making a signal from a sensor suitable for processing by data acquisition equipment - amplification, filtering, linearisation, high impedance, isolation, rms.

Supervisory control and data acquisition – SCADA refers to ICS (industrial control systems) used to control infrastructure processes (water treatment, wastewater treatment, gas pipelines, wind farms, etc), facility-based processes (airports, space stations, ships, etc,) or industrial processes (production, manufacturing, refining, power generation, etc).

Sensoray designs and manufactures embedded electronics for video capture and processing, industrial controls, and data acquisition for OEMs.
