Test- and measuring system

In Cactus measurement systems can all build their own measurement tasks. It is particularly appreciated during the audit where both electricians, operating and maintenance personnel can monitor components before and after an intervention.


The results appear in easily interpretable graphical images and graphics with high resolution. Cactus measuring system offers great flexibility for all types of measurement. The opportunities are exceptionally good for yourself to modify a lot of features so that they fit their own needs and desires.

Describe the measurement task

With the help of a form measurement tasks are descibed.
First you have to indicate which input signals to be included in the measurement.

In one single measurement several signals from various
measuring node can be combined. Signal names are shown in plain text - it's easy to choose the right ones. Hundreds of inputs can included in the measurement.

Then specify the frequency, duration of measurement and if

the measuring task should be started manually or via an external event such as a disturbance in the process. By setting a long-term-timing also available survey data, collected by the specified time before the measurement start time. Existing measurement tasks can be added or adjusted retrospectively.

Activate the measurement task

The measurement tasks are activated by a form.
After activation, the measurement task either starts
manually or automatically when a particular process event
occurs. The system can handle a wide range of measurement tasks in parallel and independently of each other.

For valves, a measurement will start automatically each
time the valve opens or closes.

Once the measurement is complete, the valve condition is checked by a large number of parameters calculated on the result. On a big discrepancy an alarm system is set. Examples of parameters calculated is the effect of pulling off and engine start, power walking and running time. The calculated values are stored in a database and can be on analysis presented such as trend curves.

Evaluate results

Once the measurement is completed, the result may be evaluated in an analysis tool based on MATLAB. The evaluation is made purely graphically in one or more graphs. The graphs can be zoomed, change scales and use lines to more easily read the values. On the measurement results you can perform many different operations: frequency and cross-spectrum, autocorrelation, or calculations based on totally own formulas.

The measurement results can be easily exported to other systems for analysis or archiving either in Excel or MATLAB format.
