EMC measurements in rail transport
To ensure safe rail operations at all times, it must be guaranteed that only one train or rail vehicle occupies a given track section. Axle counters, wheel sensors, and inductive rail contacts play a crucial role in detecting vehicle movements — and they must operate flawlessly under all conditions.
This is why EMC investigations of these systems are essential. They ensure that neither the sensors nor passing vehicles generate electromagnetic interference that could lead to miscounts or service disruptions.
EMC measurements in the railway sector are among the most demanding tasks in measurement technology. Reliable, high‑resolution, and perfectly synchronized measurement systems like the LTT24 play a vital role in ensuring safe and interruption‑free rail operations.
Here’s why the LTT24from Labortechnik Tasler is the best option:
- Up to 16 channels with 4 MHz sampling rate per channel
- 24‑bit resolution, enabling the entire operating frequency range to be captured in a single measurement
- Highly synchronous sampling across all channels — essential for accurate field analysis
- Mobile operation anywhere in the rail network, even without installed track‑switching equipment
The complete mathematical analysis — including FFT and evaluations according to relevant standards — was implemented directly in the measuring software LTTpro.
