CONVERTOR KSTID
CONVERTOR TEMPERATURE - 4 to 20 mA

Description and application

CONVERTOR KSTID
CONVERTOR TEMPERATURE - 4 to 20 mA

KSTID converters are intended for converting the signal of Ni 1000/6180, Pt 100/3850 or Pt 1000/3850 resistance-type temperature sensing elements to the unified signal 4 to 20 mA. These converters can be utilised in any control system compatible with 4 to 20 mA current output. Standard Measuring ranges of the converter are listed in the specifications table. Operating temperature range is -40 °C to 80 °C. These limits must not be exceeded even for a short time.

The sensors are designed to be operated in a 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

- Electromagnetic Compatibility in accordance with EN 50121-3-2, as amended

- 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.

  • 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.
