Whether you call them spikes, glitches, anomalies or data dropouts, these phenomena have been a problem to engineers ever since they started recording data. There are any number of reasons…
Prosig will be at Automotive Testing Expo North America from today, October 23rd, until October 25th 2012. Among the hardware and software on display will be some of the latest developments to…
There are many reasons to measure and analyze noise. It may relate to legislation or regulations that limit noise in certain environments, we could be using the noise to investigate…
The Prosig P8000 Auto-Zero function is used to remove the DC content of a signal.
For example, if you have a sine wave that is ±5 volts about 0 volts it has no DC offset. But if you have a sine wave with ±5 volt amplitude about 3 volts, then it has a 3 volt DC offset. Below is an example of these two sinewaves.
Thank you to everyone who completed our 2012 User Survey. The results were, as always, fascinating and will be used to improve our future hardware & software products. We are…
The 2nd Annual Prosig Prize for Engineering at Portsmouth University has been awarded to Ashley Stehr for his project “Developing an engineering mechanism to reduce the effects of rapid rotational motion caused by the shocks inherent with high speed craft”. Ashley is in his third year studying for an MSc in Mechanical Engineering. His project was supervised by Dr Ya Huang. Ashley’s project poster is shown below (click for a larger view).
Using 50? or 75? cable will not have any negative effects on the P8000 at all. (Generally speaking, only large voltages will damage the P8000). The impedance of the cable can only ever effect the signal the cable is carrying. (more…)
Have you ever wondered if there is a vibration condition monitoring system that can be installed anywhere and then monitored from anywhere else? Even on your smartphone? Well, there is. The following…
ODS = Motion of structure vibrating naturally (for example bridge vibration) or when excited by an unknown force (for example generator vibration). Prosig’s Structural Animation software performs ODS analysis.
OMA = Modal Analysis
Prosig’s Modal Analysis software performs OMA. (more…)
One of Prosig’s engineers was recently creating a complex worksheet application that required some complicated arithmetic to be performed on values calculated in the worksheet. Worksheet (or global) variables are ideal for this. The Variable Mods DPU also has an expression evaluator built in. Consider the following worksheet that takes a Named Element from two signals and sums them. (more…)
The digital tacho channel in a P8000 system offers better time resolution by dividing the main sample period by 16. However it is sometimes difficult to know what level the threshold should be set to so a facility to help you find the optimum level has now been added to the acquisition software. (more…)
The latest version of Prosig’s DATS software was released today and is available to download from the Prosig Support web pages. Read on to find out about some the new features… (more…)
When monitoring vibration on large gas or steam turbines and generators with fluid-film bearings, the relative movement of the shaft within the bearing is typically measured by a pair of…
