The particular use conditions of these sensors required reliability studies and type testing, to allow the sensor to work in extreme conditions, overcoming tests such as vibrations, knocks, traction and saline fog. The reference, international railway standards are: IEC349-2, IEC34-1, CEI 2-3, CEI EN 50125, IEC 61373.

Monitoring of the temperature of the rolling stock imposes high mechanical stability of the sensors. The sensors are exposed to greater vibrations and knocks caused by the speed of the air, which is extremely high and by environmental influences, especially the pressure differences on entrance to tunnels and on exiting which generate enormous mechanical loads on the sensors in use.

Temperature sensors developed specifically for high speed trains work reliably at speeds over 350 Km/h. The temperature sensors are used all over the world in high speed trains, cargo trains, regional trains and the metro.

The sensors control the temperature of the engines, gears and bearings on the carriage.

The temperature sensors are already assembled with specific cabling, based on the application as further protection for the temperature sensor cable. Guards can be used in undulated, rubber or steel tubing.

Pt100 single or double measurement resistors are used to measure the temperature of rail vehicles. The connection line can be installed with a 2, 3 or 4 wire connection. Cable output can be constructed at any angle.
