Temperature, Humidity and CO2 Sensors for Railway Vehicles

The company SENSIT s.r.o. has been in the Czech market since 1991. The company has been engaged in the development, production and supply of special temperature sensors for railway vehicles since 2004. Products for this segment must meet specific properties defined in the so-called railway standards (EN 50155, EN 61373, EN 50121-3-2, and EN 45545-2 or NFPA 130). These include; especially resistance to vibrations, electrical safety, meeting fire standards and electronic components that have to meet the conditions for electromagnetic compatibility (EMC). All these characteristics are taken into consideration during development – this is confirmed with a test report and a certificate issued by an independent accredited testing laboratory.

Standard products of the company SENSIT s.r.o. find their use in applications such as:

  • Measurements of temperature of axle bearings
  • Measurements of temperature of air for cooling of traction electric motors of shunting locomotives
  • Measurements of temperature of cooler, batteries or other components featuring flat surface
  • Secondary measurements of temperature of electrical resistors of electrodynamic brakes of electric and diesel-electric locomotives
  • Measurements of temperature, humidity and CO2 in passenger compartments of train sets and carriages, part of temperature control
  • Part of system of temperature, humidity and CO2 control in passenger compartments or temperature indication in machine compartment as part of a fire safety system
  • Measurements of temperature of outside air under the floors of railway vehicles
  • Temperature, humidity and CO2 sensors for general use, e.g., in air conditioning and temperature control systems
  • Measurement of temperature of Diesel oil – part of the system of measurement and indication of operating efficiency
  • Measurements of temperature on the surface of base boards of inverters and coolers of power components of electric locomotives
  • Indication of input and output temperature for control of hot-air heating units in passenger compartments
  • Measurements of water and sewage ducts of passenger carriages or ducts of cooling systems of Diesel engines in Diesel or Diesel-electric locomotives and train units
  • Temperatures sensor for control of heating of trolleybus trolleys
  • Measurements of temperature in motors, transmissions, machines and equipment featuring vibrations during operation
  • Sensor of temperature as part of a system for automatic heating of rail switches

At present, we can offer to our customers temperature sensors for railway vehicles, combined temperature and humidity sensors for Railway vehicles, combined temperature, humidity and CO2 sensors for Railway vehicles, converters for railway vehicles and temperature switches for railway vehicles.

Temperature Sensors for Railway Vehicles

Temperature sensors made by SENSIT s.r.o. meet all railway standards of EN 50155, EN 61373, EN 50121-3-2 and EN 45545-2 or NFPA 130. The basic outputs of these sensors include:

  • Resistance (all types)
  • Digital
  • Current 4 to 20 mA
  • Voltage 0 to 10 V

We are also preparing a version with an RS 485 output and CAN protocol.

Combined Temperature and Humidity Sensors for Railway Vehicles

Temperature and humidity sensors made by SENSIT s.r.o. meet all railway standards of EN 50155, EN 61373, EN 50121-3-2 and EN 45545-2 or NFPA 130. The basic outputs of these sensors include:

  • RS 485 (MODBUS RTU)
  • CAN / CANopen – CiA DS 301

Combined Temperature, Humidity and CO2 Sensors for Railway Vehicles

Temperature and humidity sensors made by SENSIT s.r.o. meet all railway standards of EN 50155, EN 61373, EN 50121-3-2 and EN 45545-2 or NFPA 130. The basic outputs of these sensors include:

  • RS 485 (MODBUS RTU)
  • CAN / CANopen – CiA DS 301

Temperature Converters for Railway Vehicles

Temperature/current and temperature/voltage converters made by SENSIT s.r.o. meet all railway standards of EN 50155, EN 61373, EN 50121-3-2 and EN 45545-2.

We are able to offer the converters for mounting on a DIN rail or wall-mounted.
Standard outputs include:

  • 4 to 20 mA
  • 0 to 10 V

We are also preparing a version with an RS 485 output and CAN protocol.
Inputs include: Pt 100, Pt 1000, Ni 1000.

Temperature Switches for Railway Vehicles

Temperature switches made by SENSIT s.r.o. meet all railway standards of EN 50155, EN 61373, EN 50121-3-2 and EN 45545-2.

  • Input: Pt 100, Pt 1000 or Ni 1000
  • Output: 2 relays

The temperature switch operates in 5 different modes adjustable by users. We can offer you version of temperature switches by bimetal technology.

Customized Temperature Sensors

The company SENSIT s.r.o. has its own design and production centres. We are able to produce a customized temperature or other sensors directly for a given application on the basis of customer’s requirements. Samples are usually produced within 3 weeks from project assignment. When the final design of a sensor has been approved, we proceed it to serial production. Our supplied sensors include all protocols according to railway standards.

In addition, we offer cooperation in the area of development of electronics for railway vehicles. On customer’s requirement, we are able to design and produce a product directly for your application.
