TEMPERATURE SENSORS UP TO 600 °C WITH IP 68 WITH PROGRAMMABLE CONVERTER 4–20 mA

Description and application

TEMPERATURE SENSORS UP TO 600 °C WITH IP 68 WITH PROGRAMMABLE CONVERTER 4–20 mA

These resistance-type sensors are intended for contact measurements of temperatures up to 600 °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. Sensors meet the IP 68 degree of protection in accordance with EN 60 529. The standard operating temperature range is -50 to 600 °C. The sensors can be utilised for any control systems that are compatible with output signal 4–20 mA.

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

ACCESSORIES

DECLARATION, CERTIFICATION, CALIBRATION

  • EC Declaration of Conformity – in accordance with Act 22/1997 Coll. on technical requirements on products as amended.
  • 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.
