I’m often asked whether the Prosig P8000 systems support strain gauges. And what configuration of strain gauge bridges are supported? The answer is all types of all the different configurations. (more…)
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.
A question was recently posed regarding the grounding conditions of a BNC type input. The shield or outer of a BNC cable or connector is not connected to the chassis or ground. What would happen if it was connected to ground?
When using an analogue channel input channel of a P8000, with a tachometer sensor, is it possible to utilise the tachometer processing functions as you would if you were using…
The cable resistance can be a significant factor in the accuracy of the overall measurement. It is very important indeed to consider this point. Prosig software allows the cable resistance…
The number of active arms in a strain gauge Wheatstone bridge is known as the bridge factor.
As a simple guide when selecting bridge factors the following rules apply; (more…)
The ground connection should be used if an issue has been observed in measured data, such as significant electricity supply (50Hz or 60Hz) distortion or significant noise. It must be attached…

Case Study: What can I do if the transducer I am using has a non-linear sensitivity over its measuring range?
Recently a PROSIG user wanted to measure a specific temperature parameter on a running engine. The transducer being used was one of the engine sensors built into the engine operating system to minimize engine emissions and maximize fuel economy. Unfortunately, the sensitivity of this transducer was not constant over the desired temperature range. The question then became, how can the output from this non-linear transducer be used to accurately measure the desired temperature parameter? (more…)
When working in the synchronous/angle domain, how many samples per revolution are required to study a particular order.
To study the nth order we need 
The DATS Rotor Runout Measurement package can be used on any shaft where the following probes are available... A LVDT (Linear Variable Differential Transformer) probe. This is basically a contact…
We were asked the following question…
I want to perform some cylinder head and inlet manifold vibration analysis, what should I do?
First we need to consider sensor selection (more…)
The relationship between sample rate and maximum frequency that can be analysed (called bandwidth) is a factor of 0.4. Or to look at it another way the sampling rate is…
Justin Foster (Prosig UK) explains how to set up the DATS software to switch off the P8000's cooling fans during data capture. This can be important to reduce noise during…
James Wren (Prosig UK) provides a step-by-step guide to performing a Hammer Impact Test on a structure using Prosig's DATS software and P8000 data acquisition hardware. http://www.youtube.com/watch?v=YrCM3H0_NpE
James Wren (Prosig UK) steps through how to calibrate a strain gauge for use with a Prosig P8000 system. http://www.youtube.com/watch?v=BAh9PS632Tk
A simple tutorial that explains how to use the DATS Acquisition software to set up a Prosig P8000 to capture data from a CAN-bus. http://www.youtube.com/watch?v=XeAuntGW-O4
Using a Prosig P8000 system with a 8424 DAC (digital-to-analogue) card fitted, it is possible to generate signals of any type. Typically, these might be sinewaves, chirps, random, bursts, sweeps…
For anyone curious about Prosig's DATS software & P8000 hardware running under the newly released Microsoft Windows 8 we can report that everything works as smoothly as ever. Here at…
After listening to customer feedback, we have completely re-engineered the DATS Hammer Impact software. The new version will ship with the next DATS update (not the soon-to-be-released V7.0.23). In the meantime you will be able to download and preview the new package. You will of course need a P8000 system and a DATS licence with the Hammer Impact option enabled. (more…)
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.
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…)
A simple question should have a simple answer and that answer is “No”.
As usual, however, life is never that simple. (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 P8012, P8020 & P8048 can all be fitted with the 8440 CAN-bus/GPS card. Setting up the P8000 to capture CAN-bus data is extremely simple. In the following video, James…
