Reliable pressure measurement is essential in railway vehicles – especially in the various brake systems. However, the monitoring of pressure is also relevant for other transportation applications such as pantographs, cooling systems of power units, air conditions or dampers. Due to the vibrations during the operation, the pressure measuring devices have to be extremely robust. […]
