TEMPERATURE SENSORS UP TO 400 °C WITH IP 68 WITH PROGRAMMABLE CONVERTER 4–20 mA

BBB

--%>

These resistance-type sensors are intended for contact measurements of temperatures up to 400 °C. Temperature sensors, in combination with a central holder or thermowell, can be used to measure the temperature in various applications of an industrial environment. The sensor variant with welded thread is ideal for direct measuring of mediums in ducts. The sensors meet the level of protection IP 68 in accordance with EN 60529. The standard operating temperature range is -50 to 400 °C. The sensors can be utilised for any control systems that are compatible with output signal 4 to 20 mA.

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.
