SERIE OF RESISTANCE TEMPERATURE SENSOR FOR INTERIOR

Description and application

KNS 100
SERIE OF RESISTANCE TEMPERATURE SENSOR FOR INTERIOR

The series of KNS 100 temperature sensors is designed to measure temperature of gaseous substances in spaces protected against water. In the application segment of Railway Vehicles, the sensors are used to measure temperature in passenger compartments of train units and carriages and is a part of the temperature control system.

The sensors consist of the plastic ribbing head, where the sensing element is placed. Maximum temperature range of sensor use is -40 °C to 100 °C. The sensors can be used for any control systems compatible with types of sensing elements listed in the table of technical parameters. The sensor meets ingress protection IP 30 according to EN 60529 standard, as amended.

The sensors are intended for operation in chemically non-aggressive environment.

TESTS, DECLARATION, CALIBRATIONS

  • The type tests are carried out by a notified body according to EN 50155 standard, as amended, Railway applications – Electronic equipment used on rolling stock, Art. 12.2.9, 12.2.11

- Insulation test in accordance with EN 50155, as amended

- Shock and vibration tests in accordance with EN 61373, as amended

The material of the plastic box and PCB meets 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 standard, as amended. Can be supplied with materials complying with fire safety standard NFPA 130, as amended.

  • Manufacturer provides EU Declaration of Conformity.
  • Calibration – The final metrological inspection – comparison with standards or working instruments – is carried out for all the products. Continuity of the standards and working measuring instruments is ensured within the meaning of the Section 5 of Act no.505/1990 on metrology. The manufacturer offers a possibility to supply the sensors calibrated in SENSIT s.r.o.’s laboratory (according to requirements of the EN ISO/IEC 17025 standard, as amended) or in an Accredited laboratory.
