Combined Sensors for Effective Ventilation in Rail Vehicles

With increasing demands for effective regulations in homebuilding, this trend shifts also to transport means. Railway vehicles are no exception.

According to requirements from this sector, SENSIT s.r.o. have developed Combined temperature and relative humidity sensors and Combined temperature, relative humidity and CO2 sensors with RS 485 (MODBUS) output and CAN (CANopen) protocol.

Effective Ventilation in Rail Vehicles

These combined sensors are used to measure two or all of the three variables in passenger compartments of train units and carriages and are a part of the temperature, relative humidity and CO2 concentration control systems.

With the use of the Combined temperature and relative humidity sensors and Combined temperature, relative humidity and CO2 sensors, SENSIT s.r.o. ensure:

• Creation and preservation of comfortable climate for passengers in railway vehicles
• Removal of mists on windows and walls of train units
• Energy savings based on the CO2 value evaluation by the air conditioning unit
• Increase in efficiency of the whole control system
• Costs savings

The sensors meet requirements of railway standards and type tests are carried out by the notified body:

• Insulation test in accordance with EN 50155
• Shock and vibration test in accordance with EN 61373
• Electromagnetic compatibility in accordance with EN 50121-3-2
• The plastic box and PCB materials meet a set of requirements for the R 24 materials according to the table 5 for the fire hazard level HL1-HL2-HL3 of EN 45545-2:2014

Temperature, Relative Humidity and CO2 Sensors

The design of Combined temperature and relative humidity sensor and Combined temperature, relative humidity and CO2 sensors enable:

• Temperature, relative humidity and CO2 measurement in small aesthetic design
• Better air flow around the temperature and humidity sensing element
• Significantly faster time response of temperature and relative humidity
• Convenient installation and removal of the sensor
