These resistance temperature sensors TR 021A with a connector are designed for temperature measurements of gaseous or liquid substances. The temperature range is -50 to 150 °C and these limits must not be exceeded even for a brief period. The temperature sensors with a connector consist of a metal case, in which the temperature sensing element is placed, and Lumberg M12 connector, which is an integral part of the case. The temperature sensors with a connector meet ingress protection IP 67 according EN 60529, as amended and they are designed for temperature measurent in pipelines. Their desing allows faster response to changes in temperature compared to sensors with a thermowell. They can be used as pressure accesories within the meaning of the government regulation No. 26/2003 Coll., as amanded.

The temperature sensors are designed to be operated in a chemically non-aggressive environment. The use must be chosen with regard to temperature chemical resistance of the case and the connector.

ACCESSORIES

DECLARATION, CERTIFICATION, CALIBRATION

  • 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.
