Long-term measurement
Test the long-term and temperature stability of your sensors. Seskion supports climate chamber measurements with configurable data reduction, limit monitoring and targeted error recording.
- Measurements lasting days or weeks
- Statistics to reduce data volume
- Snapshots before and after an error
Challenge and solution
Long-term measurement in practice
Sensors in a climate chamber
Multiple sensors operate over days or weeks while undergoing temperature cycles. Their data must remain plausible throughout the measurement.
The appropriate measurement system
The PSI5-Simulyzer can serve smaller setups. For high sensor counts, the modular Simulyzer-RT offers more sensor interface slots and allows different interfaces to be tested simultaneously.
Record operating conditions
Sensor supply voltages and currents, analogue reference signals and the climate chamber temperature can be recorded alongside sensor signals.
Data reduction
Continuous statistics. Detail when an event occurs.
Statistics intervals can be configured from seconds to hours. Sensor signals can also be monitored against upper and lower limits.
| Evaluation | Content |
|---|---|
| Number of measurement samples | Number of acquired values per statistics interval. |
| Mean and standard deviation | Central value and spread of the acquired readings. |
| Minimum and maximum | Lowest and highest reading in the interval. |
| Bit mask and bit setpoint | Targeted monitoring of individual bit signals. |
Capture errors in context
A limit violation triggers a real-time snapshot. The recording intervals before and after the trigger are configurable.
Software and integration
Integrate into your application
Application software
API library and a complete Windows application. The Windows application supports configurable power-on and power-off cycles.
API and programming languages
ANSI C/C++, .NET (for example C#) and LabVIEW. Adaptations for MATLAB and Python are possible.
Supported sensor interfaces depend on the measurement setup and selected hardware.
Products and development
Building blocks for your solution
The specific selection depends on interfaces, channel count and test requirements.
