TEMPERATURE SENSORS WITH A STEM AND PLASTIC CONNECTION HEAD

Description and application

TEMPERATURE SENSORS WITH A STEM AND PLASTIC CONNECTION HEAD

These resistance-type temperature sensors are intended for contact temperature measurements of liquid or gaseous substances. The plastic connection head is provided with a cable outlet ending (the terminal board is placed in the connection head) or a connector. The temperature sensor-central holder combination is suitable for temperature measurements in air condition ducts. The temperature sensor-thermowell combination is suitable for temperature measurements in tubing. The temperature sensor variant with welded thread is ideal for direct measuring of mediums in ducts. The standard operating temperature range is -30 °C to 150 °C. By using a sensor with a longer stem the upper limit of allowable temperature can be extended up to 250 °C. The temperature sensors can be utilised for any control systems that are compatible with sensing element output signals or output signals quoted in the table of sensing element types. Easy mounting of the temperature sensor is ensured by the unique “S head” design invented by SENSIT s.r.o.

The sensors are designed to be operated in a chemically non-aggressive environment.

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) or in an Accredited laboratory.
