Monitoring of coolant flow is essential for a safe and reliable operation of the traction chain. In many applications differential pressure measurement on the inlet and outlet provides a dependable determination of the coolant flow. Using a flow sensors offers the advantage, that only one sensor is needed and the temperature measurement is already included, offering advantages in the cost of integration and system design​.

Pressure sensor

• Low temperature drift for precise measurement from ramp-up to full load operation
• Can be used up to 125°C process and ambient temperature for almost all liquid cooling circuits in rail vehicles

Flow sensor

• Reliable and robust, kaliometric measuring method
• Measurement independent of the installation position
• Integrated threshold value formation on the flow value
• Integrated temperature sensor

• Ultimate accuracy for maximum motor efficiency
• Low drift ensures high repeatability under any load condition
• Flexible mounting options to match every application

Axle encoder

•     High resolution for a dynamic and precise speed measurement on the wheelset
•     Bearingless design for direct speed feedback without play
•     Robust and railway-proof design made for applications on the axle end (category 3)

• Dynamic control of the contact pressure of pneumatic pantographs
• High insulation resistance
• Diverse redundant design possible through the use of two different sensor types (e.g. PP10R and PP20R)
