## Strain Gauge Basics – Part 2 – Shunt Calibration

As mentioned in the previous post, in order to relate the measured voltage difference across the bridge circuit to a strain measurement, we need a way of calibrating the system. In most systems, including the Prosig acquisition systems, this is done by including a high-precision shunt resistor across one of the legs in the bridge. For example, the following diagram shows a quarter-bridge circuit with a shunt calibration resistor, RS, across the bridge completion resistor R2.

## Strain Gauge Basics – Part 1

The use of strain gauges with Prosig’s data acquisition systems is well understood and has been used in many real-world applications over the years [see What Is A Strain Gauge?…

## Does Prosig hardware support strain gauges? And which types?

I’m often asked whether the Prosig systems support strain gauges. And what configuration of strain gauge bridges are supported? The answer is all types of all configurations. (more…)

## Example of performing a Moving Average

This tutorial guides a DATS user through the steps required to perform a moving average on a given signal. The tutorial explains the concept of the ‘Integration Length’ and the ‘Output Interval Step’.

Initially a signal is required to perform the moving average on. In this tutorial a sine wave will be generated. A sine wave is generated using the parameters shown in Figure 1.

## Enabling Audio Playback in P8000 Acquisition Software

It is possible to enable audio playback to listen to audible frequencies while recording or monitoring when using a P8000 and the V4 Acquisition software.

## What is the maximum analysis frequency for a waterfall in DATS?

The maximum analysis frequency is always half the sample rate of the input signal.

So if your data is captured at 50kHz the maximum analysis frequency will be 25kHz.

## Creating Order Plots Using The DATS Rotating Machinery Software

In this tutorial we will be creating order plots using waterfall and intensity displays using use the DATS.toolbox and Rotating Machinery Analysis option.

To begin, a noise, vibration or other signal of interest should be captured along with a tachometer signal.

In Figure 1 we have loaded a time series (in this case an acceleration signal) and a time series of a tachometer pulse train into the DATS software.

## What is waterfall frequency spacing? And how does the DATS parameter ‘Requested Frequency Spacing’ work?

Let us try to understand what waterfall frequency spacing is. Waterfall frequency spacing is the gap between spectral lines in an FFT plot.

For example, if you had an analysis frequency of 0Hz to 100Hz and 100 spectral lines, then Frequency Spacing is 1Hz.

So why is there a ‘Requested Frequency Spacing’ and an ‘Actual Frequency Spacing’? (more…)

## What is “waterfall smearing”?

When analysing a waterfall or performing order analysis it is important to consider the frequency resolution or the frequency spacing.

There is often a desire to increase the resolution to finer and finer detail. But that is a process of diminishing returns, and actually fraught with danger. And that danger is waterfall smearing. (more…)
