These thermocouples are designed for temperature measurement of nonaggressive liquid and gas, and also of aggressive medium which does not destruct thermowell material, at elevated temperature or presence of protective (heat-insulating) shield at wire output from protective fitting.  Cable temperature-sensing element is outside of protective tube, extension length is equal to Ê.Sensor can not be dismantled. Fitting is made of commercial quality carbon steel with protective coating.
Sensors can be of explosion protection type 0ExiaIICT6 X  according to GOST 30852.10-2002. For further details see "Alternative designs & Ordering information" below.

If required, thermocouples with  4-20 mА DC signal and/or digital signal via HART, PROFIBUS-PA, FOUNDATION Fieldbus protocol, can be equipped with remote measuring transmitters.
