Condition monitoring is achieved by monitoring and logging the condition of rotating assets as well as recording and presenting the data acquired, in a way that engineers can easily understand what is happening. A typical condition monitoring system has the following components:

Condition Monitoring
Sensors convert the physical value to be measured into an electrical signal. Select the correct sensors for the signal type that you are measuring and a sensor with an output signal that can be read by a DAQ device.

A Data Acquisition (DAQ) device converts electrical signals into data that can be read by software. National Instruments provide a wide range of devices for Data Acquisition, the most flexible being compactDAQ devices. These are configurable for a wide range of signals and channel count.

Datalogging Software to log the data to disk and to display information on charts. When selecting data logging software for your application, it is worth considering how flexible it needs to be and the output that you need from your data logging system.


Our condition monitoring software template is a great starting point for your next condition monitoring application. It easily integrates with NI compactDAQ devices, and the NI Sound and Vibration Toolkit to process and analyse vibration signals from the NI 9230/2/4 modules.

Condition Monitoring

Key Features:
1. Switch between Live Values and Trend view. Trends can show logged data at a variable logging rate (you specify this in the settings) and show up to 12 hours of test data.
2. Simple toggle button to start and stop monitoring
3. Monitor alarm condition for inputs. This can be integrated to toggle a safety relay or other output relay for system control.
4. Adjust the display range during a test to zoom in on an area of interest or show the entire test
5. Optionally show all system inputs or hide some inputs to highlight just signals of interest.


When monitoring is started, the software will log all system inputs at the logging rate you have configured to a .csv text file.
Values are updated on all screens – live values and trend charts. This keeps operation of the system simple and ensures that all data is recorded during a test.
