Product details about "Immersion temperature probe - Mini series"

DESCRIPTION AND APPLICATION

All of this resistance temperature sensors of the MINI series are designed for measuring the temperature of liquid or gaseous substances in the temperature range between -30 and 150°C. The plastic connection head is equipped with a cable outlet (the terminal block is placed in the connection head) or a connector.

la sensor-central support combination suitable for temperature measurements in air conditioning ducts. Lakesensor-thermowell combination suitable for temperature measurements in tubes. The sensor variant with welded thread is ideal for direct measurement of fluids in pipes.

By using a sensor with a longer rod, the upper limit of the allowable temperature can be extended up to 250°C. The sensors are designed to operate in a chemically non-aggressive environment.

ACCESSORIES

  • Central plastic support
  • JS 130 stainless steel thermowell
  • K 120 central metal support
  • CONEC 43-00092 input connector
  • Connection cable with straight connector RKt or rectangular connector RKWt
  • Screw with collar or cutting rings - if different immersion lengths of the temperature sensor are set

DECLARATION, CERTIFICATION, CALIBRATION

  • The manufacturer provides an EU declaration of conformity.
  • Calibration - The final metrological control - comparison with standards or working instruments - is carried out for all products. The continuity of standards and work measurement instruments is ensured within the meaning of article 5 of Law No. 505/1990 on metrology. The manufacturer offers the possibility of supplying the calibrated sensors (according to the requirements of EN ISO / IEC 17025) or in an accredited laboratory.
