These sensors are designed for temperature measurement in liquid and gaseous non-corrosive media, and also corrosive media that do not damage protective cover material. Sensors are recommended to be used together with UNKJ thermowell.
PRTD 101K and 102K thermometers are designed for cryogenic temperature measurement. PRTD 101H and 102H is an alternative to copper thermocouple for temperature measurement up to 200°С.
To provide guaranteed sensor-connector contact we recommend to install
CRTD (PRTD) 102 sensors without mounting elements, by means of mounting fitting UNKJ 038 or movable fitting UNKJ 031 (see "UNKJ units and components" section).
Sensors can be of explosion protection type 0ExiaIICT6 X or 1ExdIICT6 according to GOST 30852.10-2002. For further details see "Alternative designs & Ordering information" below.
Terminal heads can be equipped with measuring transmitters with  4-20 mА DC output signal according to GOST 26.011 and/or digital signal via HART, PROFIBUS-PA, FOUNDATION Fieldbus protocol, and also cable glands for additional cable fastening, and metal hose fastening, if required.
