Signal Conditioners with Built in Data Logging

An application note from our supplier Acromag.

Defining the Problem:

A manufacturer of sensors and electrical controls does burn-in testing for troubleshooting purposes. A test system that can operate with either an Android® or iOS® mobile device is preferred.

System Requirements:

The application requires a product that can monitor a variety of signals, provide analogue or limit alarm outputs and have data logging capability. The test duration could be several minutes to a day and the results need to be saved in an Excel format

Implementing the Solution

1. Download the Acromag Agility™ mobile app from the Google Play™ store or Apple® App Store.

2. Open the Agility mobile app and go to the configuration screen. Enable the alarm output and enter the set point and deadband. When the set point is reached, this output will be 5V or 0V, normal or reverse acting. It can drive an external relay or feed a TTL input.

3. Navigate to the diagnostic screen where the trending feature is accessed. There are two types of indicators available, a digital display or graphical representation.

4. Enter a polling period from 0.5 sec to 60 sec. With a capacity of 5000 samples, the duration of saved data can be up to 83 hours. This is a moving average where sample # 5001 is added to the total and # 1 is dropped off.

5. Tap save data, then tap start polling. The Agility app automatically creates an Acromag folder in the mobile device and saves the input values to a spreadsheet in that folder. The data then can be emailed by tapping the share button.

Dewesoft - Motor and Inverter Testing Application

Combined motor and inverter testing is the Power Analysers king’s class and affords a high number of input channels for voltage and current measurement and completely synchronised data acquisition. The Dewesoft R8D power analyser makes it possible to measure 8x three phase systems within just one device. That unique feature allows to measure whole power systems (e.g. electric vehicle, aircraft, and ship) completely synchronous. It combines all functionalities of motor and inverter testing as described above and further allows to measure other parameters like speed, torque, temperature, video, GPS, CAN and a lot more as well.

Up to now typical test bed applications needs the usage a couple of instruments (Power Analyser, Scope, Data Logger, CAN reader etc.)  The Dewesoft Power Analyser makes it possible to do all these analysis within just one device. All data can be stored in the full-sampling rate and all analysis can be done already during measuring. The unique post-processing functionality allows also doing all analysis (mathematic, power analysis) after the measurement on the personal notebook. It’s even possible to change settings or correct for example phase voltages if they were connected wrong. In this case the measurement doesn’t have to be repeated. This is never experienced testing.

Highlights

• Efficiency, Power & Power Quality analysis
• Up to 8 three phase systems
• Different frequencies (DC, 16,7Hz/50Hz/ 60Hz/400Hz/800Hz/variable frequency)
• Raw data analysis, Transient recording, Data logging, Scope, Vector Scope
• Additional measurements like speed, torque, temperature, etc.

Typical configuration

• SIRIUS R8D
• 12x Voltage
• 12x Current
• 1x Torque
• 1x Speed
• Additional inputs (analogue, digital, counter, GPS, CAN, video, etc.)
