Is it important to consider the cable resistance when using strain gauges?
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…
How should the bridge factor be selected when using strain gauges?
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…)
When should I use the ground connection on my P8000 data acquisition system?
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…

Creating calculated signals with DATS Acquisition
Case Study: What can I do if the transducer I am using has a non-linear sensitivity over its measuring range?
Abstract
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…)
How Many Samples Per Revolution Are Required To Study A Particular Order
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 [latex]2*n[/latex] samples per revolution. (more…)

New Hammer Impact Software – Preview coming soon
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…)
Why does Auto-Zero have no effect for IEPE sensors?
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.
Should I use 50 Ohm or 75 Ohm cables with a Prosig P8000 system?
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…)
There are tachometer signals available on the vehicle CAN-bus. Can I use these signals instead of connecting my own tachometer signal?
A simple question should have a simple answer and that answer is “No”.
As usual, however, life is never that simple. (more…)
Automatic Tacho Processing Using A Prosig P8000
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…)
