About Us

Tradition since 1991

History and the present days

Profile of SENSIT s.r.o.

The SENSIT s.r.o. Company from Roznov pod Radhostem, is known in the Czech market since 1991. SENSIT s.r.o. has begun the development, manufacture and supply of special temperature, humidity, CO2, atmospheric pressure and VOC sensors for railway vehicles since 2004. Products for this segment must have specific properties defined in the so-called railway standards (EN 50155, EN 61373, EN 50121-3-2, EN 45545-2 or NFPA 130 as amended). They include especially resistance to vibration, electrical safety, they have to meet fire standards, and electronic components 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 independent technical and properly accredited testing laboratory.

As the development has shown, the term "temperature, humidity, CO2, atmospheric pressure and VOC sensors for railway vehicles" means:

  • The temperature sensors for electric locomotives, measuring the temperature of axle bearings, air in the cab driver, driver's seat, auxiliary power unit, transducer baseboards, outdoor air, cooling air of traction motors, chokes, etc.
  • The temperature sensors for electric locomotives, measuring the temperature of intake air, air in the cab driver, temperature in the engine compartment, temperature of oil, diesel fuel, coolant, auxiliary power units, axle bearings, etc.
  • The temperature sensors for compartment coaches, passenger compartments of motor and electric units, where they measure the temperature of outside air, piping and tanks with service and waste water, axle bearings, spaces with auxiliary power units, temperature, humidity, CO2, atmospheric pressure and VOC sensors are a part of the air conditioning units and fire protection systems.
  • The temperature sensors for trams, measuring the temperature of transducer baseboards, heat exchangers; temperature, humidity, CO2, atmospheric pressure and VOC sensors are a part the air conditioning units and seat heating control.
  • The temperature sensors for underground trains, measuring the temperature of transducer baseboards, axle bearings, spaces with auxiliary power units; temperature, humidity, CO2, atmospheric pressure and VOC sensors are part of the air conditioning units and fire protection systems.
  • The temperature sensors for trolleybuses, measuring the temperature of transducer baseboards, current-collection pulleys, etc.
  •  The temperature sensors measuring the temperature of rails and railroad switches and the temperature sensors for the interior of electrical switchboards and other railway equipment used in security systems of railway infrastructure are included in the category of "temperature sensors for railway vehicles".

SENSIT, s.r.o., is also engaged in the manufacture of temperature sensors in various industries. The standard temperature range of the sensors is from -200 °C to 1 100 °C and the diameter of the resistance temperature sensors is from 1.0 mm. In recent years, company's product range has expanded with humidity sensors, CO2 sensors, level sensors, flow sensors, atnospheric pressure sensors, VOC sensors and inductive sensors.

Competitiveness of Company's products is constantly checked out on the Czech market and abroad. With regard to long-term supply for major manufacturers of technological units and components in the fields of:

Custom and small series production 

As a significant competitive advantage, SENSIT s.r.o. maintains the capability of small series or piece production. High flexibility in relation to the special requirements of customers enables the company to react flexibly to their needs in terms of composition of the custom range, as well as in time performance. 

Production quality and customer care 

SENSIT s.r.o. is aware of the fact that the quality of all work and the associated technical level and quality of production are critical for the existence of the company. Therefore, the company has been committed in the long-term and systematically to creating open and ethical relationships with customers, suppliers, its own employees as well as other interested parties.

The high level of quality of its products is ensured, among other ways, through the performance of regular and repeat type tests of the properties of products or through the sophisticated operation of cycling 7 to 10 cycles in temperature intervals from -10 to 80 °C with the objective of detecting critical manufacturing defects. A standard part of production processes is initial calibration and output inspection. The final products are thus supplied in the guaranteed quality, which is reflected in the low percentage of justified complaints.

SENSIT s.r.o. meets the requirements of standards EN ISO 9001, EN ISO 14001 and OHSAS 45001 for all areas of its activities, as evidenced by valid certificates.

In relation to specific products, the company complies with the specified requirements of Act No. 22/1997 Coll., as amended. In the case of specific parameters and properties of products, corresponding certificates and test reports (e.g. coverage, mechanical resistance, vibration, electric strength, etc.) are issued on the basis of type tests in accordance with specific technical standards.

Snímače teploty Pt 100 a Pt 1000

Snímače pt100 a pt100


Snímače teploty společnosti SENSIT s.r.o. nacházejí uplatnění v oboru měření a regulace jako zdroje primární informace o teplotě pro řídící a regulační systémy tuzemských i zahraničních výrobců. V posledních letech firma dodává i snímače vlhkosti a snímače proudění. Jednou z vlastností těchto teploměrů je jejich rychlá časová odezva na změnu teploty , která je závislá na konstrukci snímačů teploty. Konstrukce a provedení určitých snímačů teploty umožňují přímou montáž teplotních čidel do potrubí bez použití jímek.


SENSIT má ve výrobě různých typů senzorů teploty dlouholetou tradici. K moderním snímačům teploty nabízí společnost SENSIT i podpůrnou elektroniku, například digitální teploměry, převodníky a nebo teplotní spínače. Snímače průtoku (snímače proudění) jsou určeny pro kontaktní měření rychlosti plynných látek. Kombinací snímače průtoku (snímače proudění) a středového držáku je možné použít snímače proudění v klimatizačních kanálech nebo potrubích.


Společnost SENSIT s.r.o. provádí záruční i pozáruční opravy vlastních výrobků - snímačů teploty (teplotních čidel), snímačů proudění, snímačů vlhkosti, převodníků, spínačů teploty, termostatů a digitálních teploměrů.

Indukční snímače

indukční snímače


Vývojem, výrobou a prodejem odporových snímačů teploty se společnost SENSIT zabývá již od roku 1991. Odporové teploměry jsou součástí měřidel spotřeby tepla. Většina typů snímačů jsou určeny pro provoz v chemicky neagresivním prostředí. Na zakázku je ale SENSIT schopen vyrobit a dodat snímače teploty pro chemicky agresivní prostředí. Je vždy ale nutné specifikovat jaké. SENSIT nabízí také indukční snímače polohy různých typů a indukční snímače otáček.


V portfoliu SENSITU má své místo i školení o vlastnostech odporových čidel, o sortimentu snímačů teploty, o kalibraci měřidel teploty. SENSIT s.r.o. dále provádí kalibrace odporových snímačů teploty (čidla Pt 100, Pt 1000, Ni 1000, NTC termistory), termočlánků a snímačů teploty s aktivním výstupem (proudovým, napěťovým a nebo RS 485). Pro zvýšení spolehlivosti a nebo tam, kde je snímač teploty nepřístupný pro případnou výměnu, SENSIT nabízí možnost zapouzdření dvou a více teplotních čidel do jednoho pouzdra snímače teploty. Jedná se obvykle o snímací prvky Pt 100, Pt 500, Pt 1000, Ni1000, Ni 10 000, Ni 2226 = T1 popřípadě i NTC termistory.


Řádově tisíce odběratelů snímačů teploty SENSIT lze rozdělit do zhruba deseti skupin podle aplikace: Bílá technika, teplárenství, lékařská elektronika, potravinářství a gastronomie, gumárenský průmysl, stavebnictví a zajištění provozů budov, kolejová vozidla, vytápění a obnovitelné zdroje energie, laboratoře a strojírenství. Nepatrnou část z posledního masivního nasazení snímačů teploty SENSIT může laická veřejnost spatřit na stěnách nákupního centra Nová Karolína v Ostravě, kde jsou viditelnou součástí regulace vnitřní teploty.
