Our sensors are used worldwide in high-speed trains, cargo and regional trains, metros, trams and hybrid buses. They monitor the temperature of traction motors, gears and wheel-set bearings.

Temperature sensors for rail vehicles are produced according to customer requirements. Each sensor consists of the housing with measuring transducer, a cable connection, the cable screw connection and, if applicable, a plug connection. Solid and highly vibration-resistant brass housings in various versions are used for the housing. The cable connection port is available in any angle from 90 to 180 degrees. The stainless steel protective pipe designs have a diameter of Ø 5 mm to Ø 12 mm and a length of up to 250 mm. The size and position of the fastening holes are adjusted accordingly. Single or double Pt100/Pt1000 chip sensors in 2, 3 or 4 wire circuits are used as standard.

The cable connection is responsible for the transmission of the sensor signals and is the most important link between the sensors and plug connections. EPHYMESS therefore uses screened special hose lines that fully meet the requirements regarding mechanical, chemical and thermal stability. They usually consist of a silicone-free, halogen-free, 4 wire, screened hose line with an operating temperature range of -40°C ... +150°C. The cable connections are resistant to stone chipping, cleaning fluids, salt, alkali and other external influences.  Plastic, metal corrugated tube or rubber fabric hoses offer additional mechanical protection.

The plug connections form the sensor systems interface to further components and allow easy, problem-free connection of the sensor technology to the analysis units. Standard plug connections from various manufacturers are used (as requested by customers). Adapted to the specific requirements and the measuring signals to be transmitted, they are produced in a sealed design. Variants with isolating plugs enable short cable lengths with direct cable laying on and through the housing. When system plugs are used, the number of plug components and individual parts is reduced as the lines are guided together. This reduces the required assembly and maintenance work.

When selecting the right components, high standards are demanded for safe operation, low construction effort, low vulnerability to malfunction and high availability. EPHYMESS temperature sensors for rail vehicles combine all these criteria and can be put together in a large number of combinations.
