NEW DESIGN of the interior temperature sensor for Railway Vehicles

Dear business partners,

we would like to introduce you new modern design of an interior temperature sensor with a resistance, current and voltage output. Interior temperature sensors meet all requirements of railway standards: EN 50155, EN 61373, EN 50121-3-2 and EN 45545-2.



These interior temperature sensors are designed for temperature measurement in rooms, e.g. in schools, theatres, offices, interiors of residental houses and also production halls. In the application segment of Railway Vehicles, it is used to measure temperature in passanger compartments of train units and carriages and is a part of the temperature control system. Interior temperature sensors can be used also for measurement temperature in electrical cabinets. The high quality material and suitable design of the interior temperature sensor ensure that the sensor do not distrubning even interiors with high aesthetics requirements.

The design change of the casing of the interior temperature sensor provides: 
  • better air flow around the sensing element
  • significantly faster time response
  • compared to the original version, also convenient installation and removal of the sensor
  • material of the case meets standards of EN 45545-2

The type tests are carried out by a notified body according to EN 50155 Railway Applications - Electronic equipment used on rolling stock, Art. 12.2.7, 12.2.8, 12.2.9, 12.2.11
- Art. 12.2.7, 12.2.8 according to EN 50121-3-2 - Electromagnetic Compatibility
- Art. 12.2.9 according to EN 50155 - Insulation test
- Art. 12.2.11 according to EN 61373 - Shock and Vibration tests

The material of plastic box and PCB meet a set of requirements for the R 24 materials according to the Table 5 for the fire hazard level HL1-HL2-HL3 of the EN 45545-2:2014 standard.


The new design and construction of the interior temperature sensor reduces the effect of the temperature of the electronics on the measurement, mainly with current and voltage output. It ensures higher measurement accuracy. The plastic box is made of LEXAN, which meets parameters of EN 45545-2.
