Rail Industry and Heavy Machinery

We have a wide range of Physical and Electrical Sensors, Electrical Circuit Interfaces, Instrumentation and Data Acquisition for the Rail Industry and Rotating Machinery.

  • Development & Certification Testing
  • Sensing Components; Speed, Pressure, Acceleration, Angle, Position, Vibration, Distance, Force, Torque, …
  • Test benches, Structural Testing Rigs & Railway Track Monitoring
  • Operation Monitoring & Maintenance Tools

Rail Vehicle Measurements


High Voltage Measurement – up to +/- 1000 V

 

Acoustic and Vibration Measurements
with Bandwidths from 1 Hz up to 48.6 kHz (-3 dB)

 


Aero-Dynamic Pressure Testing – individual
Pressure Sensors and multi-port Pressure Scanning

 


Telemetry for rotating shafts and machinery

 



Communication Bus interfaces to other devices for synchronized Data Collection:

  • CAN bus, IPT.COM, EtherCAT, MVB (Multi-Vehicle Bus) and Programmable module for customized interfaces

ECU protocols in available:

  • J1939, CCP, KWP 2000, XCP, Diag on CAN, GMLAN, OBD, UDS


Passenger Ride Comfort Testing according to industrial standards, UIC 513, EN 12299 and JIS E4023


Facility Testing that utilizes similar Hardware and Software to that of the vehicle Data Acquisition, providing Correlated Data between the Field Data collected and the Facility Data collected. The same input amplifiers, filters and sample rates on the Hardware and the same data processing and data analysis Software.

Examples of the Facility Testing:

  • Climatic Testing of HVAC in Climatic Chambers
  • Aero-Dynamics Wind Tunnels
  • Braking Systems Dynamometers
  • Tilt Systems Test Rigs
  • Engine Test Cells
  • System Endurance Test Rigs
  • Structural Strength Load Testing and Fatigue Life Testing
