Description
Technical characteristics

104

is designed for indoor air temperature measurement. 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 of PRTD (CRTD) 104-014… and PRTD (CRTD) 104-018… 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 Fieldbusprotocol, and also cable glands for additional cable fastening, and metal hose fastening, if required.
