Thanks to a forty-year track record of pioneering achievements in piezoelectric measuring technology, Kistler has built up the specific application expertise that is essential for capturing highly dynamic events in harsh environments.

Kistler can implement complete measuring systems to characterize high-energy materials. Our portfolio includes piezoelectric pressure sensors for the highest pressures (up to 10 000 bar), high-end data acquisition systems with maximum bandwidths, and flexible analysis software.

Pyrotechnics, vehicle technology as well as security and safety engineering: in all these fields and more, Kistler's long-lasting high pressure sensors complemented by our DAQ systems deliver precise measurements for high-pressure applications (up to 10 000 bar) in very dynamic processes.

Reliable measurement of dynamic high pressure applications

Characterization of high-energy materials using pressure measurements sets demanding requirements for various aspects of sensor technology – such as mechanical stability, dynamics, thermal shock and the installation location. Kistler's product portfolio reflects our application-specific expertise, gained over many years of working with pyrotechnic applications, such as airbag and closed vessel testing.

Thanks to scientific field research and physical modeling, the new system makes use of an optimized sensor layout that combines high precision with easy installation – only minimal track closures are required, or none at all. As well as measuring weight-related parameters, Rail WIM from Kistler collects and calculates data about rail vehicle safety and track usage. 

Multi-purpose comprehensive WIM solution

Applications include Safety in Operation (derailment prevention, verification of train weight, spacing between trains, speed monitoring and bridge protection, etc.), Preventive Maintenance (infrastructure wear and tear, rolling stock condition monitoring) and Compliance (overload, wheel defects, incorrect weight declaration and incorrect train length).

Rail Weigh In Motion from Kistler includes these functions:

  • Measurement of vehicle and train weight
  • Vehicle identification, classification and statistics
  • Accurate speed measurement
  • Detection of unbalanced vehicle loading
  • Detection of axle parallelism
  • Condition monitoring of wheels and bogies (flat spots, spring defects, axle/wheel distance)
  • Self-monitoring with frequently used and known vehicles
